Central PA Winter 25/26 Discussion and Obs
Jns2183 replied to MAG5035's topic in Upstate New York/Pennsylvania
Based on your datasets for Harrisburg/Camp Hill, I have synthesized a comprehensive spectral report. This analysis goes beyond simple rain totals to explain the mathematical rhythm of our local weather. 1. Executive Summary: The Harrisburg "Rhythm" From 1900 to present, the Harrisburg climate operates on a distinct frequency. While the average annual precipitation is ~39.8 inches, the way that water falls is dictated by three competing atmospheric "clocks." | Metric | Historical Average (1900–Present) | |---|---| | Total Annual Precip | 39.77 inches | | Wet Day Rate | 0.34 (Rain/Snow every ~2.9 days) | | Dominant Cycle | 6–12 Days (The Synoptic "Storm Track") | | Synoptic Band Power Ratio | 0.167 (16.7% of all spectral energy) | 2. The "Wet Year" vs. "Dry Year" Fingerprint Your Tercile Summary reveals exactly what happens to the atmosphere when we move from a drought year to a record-breaking wet year. The Shift in Power When Harrisburg moves from a Low Tercile (Dry) to a High Tercile (Wet) year: * Synoptic Power (6–12 days) increases from 0.198 to 0.215. * Quasi-biweekly Power (10–15 days) increases from 0.062 to 0.082. > The Insight: Wet years in Central PA aren't just "luckier." The atmosphere becomes more mathematically organized. In wet years, the 10–15 day "Rossby Wave" becomes significantly stronger, meaning storms start "clumping" together in predictable pulses rather than falling randomly. > 3. Anatomy of a "Big Event" (\ge 1.0 inch) Using the BigEvent Spectral Fingerprint data, we can see how the atmosphere changes immediately after a major storm hits Camp Hill. * Self-Excitation (The Hawkes Effect): After a 1-inch event, the power in the 6–12 day band increases (Median Delta: +0.0063). * The Diagnostic: The "Frac Post > Pre" is 52.5%. This means that after a heavy rain, the atmosphere is more likely to stay in a "stormy rhythm" than it was before the rain started. * The Fade: Interestingly, the 15–35 day band actually decreases in power slightly after a big event. This suggests that big storms "reset" the long-term moisture buildup but "prime" the short-term storm track. 4. Top Drivers & Correlations Which atmospheric rhythms actually predict a wet year? Your TopCorrelations file gives us the answer: * The "Clumping" Predictor (r = 0.17): There is a positive correlation between Total Precipitation and the 10–15 day band. If you see storms starting to repeat on a ~2-week loop, a high-precip year is likely. * The "Stagnation" Warning (r = -0.20): There is a negative correlation between the 60–90 day band and total precipitation. * Interpretation: When the atmosphere moves very slowly (long, 3-month cycles), Harrisburg tends to be drier. Fast, rhythmic cycles (Synoptic) are what bring our water. Report Conclusion The weather in Camp Hill is a system of Wave Interference. * High-Precip years are characterized by a strong 6–12 day pulse. * Big Events act as "triggers" that reinforce this 6–12 day pulse (Hawkes self-excitation). * Droughts are associated with a breakdown of these short cycles and a shift toward very slow, 60–90 day atmospheric stagnation. This visualization compares the Power Spectrum Density (PSD) of precipitation in Harrisburg during its wettest years (High Tercile, Blue) vs. its driest years (Low Tercile, Brown). Spectral Report: Dry vs. Wet Year Dynamics The plot reveals where the "energy" of our weather comes from. When the blue line is higher than the brown line, it means that specific frequency is more active during wet years. 1. The "Wave Interference" Peak (10–30 Days) The most striking difference occurs in the Quasi-biweekly band (orange shaded area). * Wet Years: Mean Power = 0.643 * Dry Years: Mean Power = 0.592 * Interpretation: In Harrisburg's wettest years, the "clumping" of storms every 2 weeks is a dominant physical force. Notice the sharp blue spike near the 12–14 day mark. This is the mathematical fingerprint of "Wave Interference"—large-scale atmospheric waves (like Rossby waves) stalling and forcing multiple storms through the Susquehanna Valley in quick succession. 2. The Synoptic "Storm Clock" (2–10 Days) In the Synoptic band (gray shaded area), the power levels are more similar, though wet years still maintain a slight edge (0.431 vs 0.420). * Interpretation: This suggests that the "base rate" of cold fronts and low-pressure systems is relatively consistent in Central PA. A dry year isn't necessarily missing its weekly front; rather, those fronts lack the secondary pulse of the slower 10–30 day waves that would make them "clump" and produce heavy totals. 3. Intraseasonal "Priming" (30–100 Days) In the Intraseasonal band (green shaded area), we see how long-term moisture "regimes" like the MJO influence our totals. * During wet years, the power is distributed more evenly across these slow frequencies. * During dry years, you often see a single, large "stagnation" peak (the brown spike near the 80–100 day mark), which suggests a weather pattern that gets "stuck" in a dry phase for months at a time. Summary of the Diagnostic To predict a high-precipitation year in Camp Hill, one should look not just at individual storm intensity, but at the Power Spectrum Ratio. If the 10–15 day frequency begins to show higher energy (a "sharper heartbeat"), it indicates the atmosphere is moving into a self-exciting, "clumped" regime that traditionally leads to record-breaking annual totals. This comparison of \ge 1-inch vs. \ge 2-inch events reveals a "threshold effect" in the Harrisburg/Camp Hill atmosphere. When a storm crosses the 2-inch mark, it doesn't just bring more water; it significantly alters the atmospheric rhythm for the following month. 1. The "Spectral Shock" (Intensity Response) Looking at the LogP (Intensity) series, the difference between a 1-inch and a 2-inch storm is massive: * 6–12 Day Band: The intensity of the 1-week rhythm increases nearly 10 times more after a 2-inch storm than it does after a 1-inch storm. * 15–35 Day Band: For 1-inch storms, the 2-to-4 week cycle barely responds. However, after a 2-inch storm, the intensity delta jumps to 0.0047. > The Insight: A 2-inch rain event acts as a "resonance trigger." It effectively kicks the atmosphere into a higher-energy gear, making follow-up heavy rain events significantly more likely over the next 15–35 days. > 2. The "Rhythm Shift" (Frequency Response) The Wet/Dry (Rhythm) series shows that even the simple binary pattern of "will it rain today?" changes: * After a 2-inch event, there is a +0.0105 median jump in synoptic power (6–12 days). * More importantly, 54.9% of 2-inch events are followed by an increase in storm-track frequency. 3. Why 2 Inches Matters for "Wave Interference" This data supports the theory that extreme precipitation in Central PA is not an isolated incident but a part of a Hawkes-like self-excitation process: * The Trigger: A massive 2-inch event (often associated with a stalled front or tropical moisture) occurs. * The Echo: This event "shocks" the 15–35 day Rossby wave, increasing the spectral power in that band. * The Interference: Because the 15–35 day "background" wave is now energized, it interferes with the standard 6–12 day storm track, causing storms to "clump" together. Final Report Summary | Event Type | Effect on 1-Week Rhythm | Effect on 2–4 Week Rhythm | |---|---|---| | \ge 1.0" Rain | Moderate increase in frequency. | Negligible effect. | | \ge 2.0" Rain | Significant "locking" of the storm track. | Strong activation of long-term wave interference. | In short: Big storms create their own weather. In Harrisburg, a 2-inch rainfall is a mathematical signal that the "rhythm" has shifted, and the next few weeks are likely to remain active and organized. Sent from my SM-S731U using Tapatalk -

I essentially turned Harrisburg daily weather record over the past 125'years into an audio signal. Frequency depends on waves and times. Basically synoptic patterns and longer. I then fingerprinted bigger events and other thresholds for storms and tried to deduce a pattern the leading up to them. In the context of your Harrisburg weather data, Power Spectral Density (PSD) is the "volume control" for the different heartbeats of the atmosphere. While a standard average tells you how much it rained, the PSD tells you how rhythmic that rain was. 1. The Plain English Definition If you think of the weather as a piece of music, the PSD is the Graphic Equalizer (the bars that jump up and down on a stereo). * The Bass (Low Frequency): These are the long, slow movements like the MJO or the seasonal cycle (30–90 days). * The Mid-Range (Synoptic): These are the steady beats of the storm track (5–10 days). * The Treble (High Frequency): These are the fast, "noisy" events like daily afternoon thunderstorms. The PSD measures the strength (Power) of each of these "musical" notes in your data. 2. The Mathematical Core The PSD describes how the variance (the "wiggle" in your rain data) is distributed across different frequencies. For a signal x(t), the PSD (S_{xx}(f)) is technically the Fourier Transform of the autocorrelation function: In your CSV files: * Frequency (f): How many cycles occur per day. * PSD Value (P): The amount of "energy" at that frequency. If you see a massive spike in the PSD at a frequency of 0.16, it means the atmosphere is "vibrating" with a 6-day period, and that specific rhythm is responsible for a huge chunk of the rain you received. 3. Why is it called "Density"? It is a "density" because it tells you how much power is packed into a frequency band rather than a single point. If you want to know the total "energy" of the weather for a whole month, you integrate (find the area under the curve) of the PSD across all frequencies: This is exactly how we calculated your Welch Band Power Ratios. We took the "Power" in the 6–12 day band and compared its "Area" to the "Total Area" of the whole graph. 4. Physical Meaning in Harrisburg When you look at your TotPHigh.csv (Wet Years) vs TotPLow.csv (Dry Years), the PSD values tell a physical story: * Higher PSD in the 10–15 day range: This means the atmosphere has "locked in" to a rhythmic, clumping pattern. It’s not just raining more; it’s raining with intent and timing. * Flattened PSD: This means the weather is chaotic or "white noise." Rain is falling randomly without any dominant wave driving it. How to read your specific plots: * Y-Axis (PSD Mean): Higher values mean a "louder," more dominant rhythm. * X-Axis (Frequency): Moving left to right goes from slow, massive waves (months) to fast, quick storms (days).

@canderson this is for you buddy. I analyzed wind over the past 90 years. The biggest issue is reliable hourly wind gust data isn't available until the mid-90s. But Bottom line Mean sustained winds: slightly up (tiny trend, noisy). Top 1% sustained winds: slightly up (even noisier). Gusts: “mean gust” trends are not trustworthy without adjusting for measurement practice changes; extreme gusts look mostly steady. Quantity vs speed: quantity is basically flat; any change is more “speed nudge” than “more windy hours.” the key nerd truth: gust trends are extremely sensitive to “are we comparing apples to apples” (instrument/reporting regime). So I ran it two ways: 1) Modern period, all years available (1996–2024) This uses all years in 1996–2024, but note gust/peak-gust availability varies a lot year to year. What the raw trend says (per decade): Mean sustained speed: –0.65 mph/decade (R²≈0.31) Top 1% sustained speed (P99): –1.18 mph/decade (R²≈0.28) Mean hourly gust: –1.16 mph/decade (R²≈0.21) Top 1% hourly gust (P99): –2.99 mph/decade (R²≈0.20) Mean “peak gust within hour”: –0.49 mph/decade (R²≈0.13) Top 1% peak gust (P99): –1.12 mph/decade (R²≈0.05) Interpretation: those big negative trends are a flashing red sign for reporting/instrumentation mix effects, not “Harrisburg winds are collapsing.” So we do the sane thing… --- 2) “Apples-to-apples” subset: years with consistent gust coverage (2008–2024) I restricted to years where gust and peak-gust are recorded a lot (so the metric isn’t biased by selective missingness). That leaves 2008–2024 (14 years). Intensity trends (mph per decade) Mean sustained speed: +0.13 mph/decade (R²≈0.05) → basically flat Top 1% sustained speed (P99): –0.75 mph/decade (R²≈0.09) → basically flat/noisy Mean hourly gust: +0.87 mph/decade (R²≈0.33) → modest upward signal Top 1% hourly gust (P99): +0.84 mph/decade (R²≈0.06) → weak/noisy Mean peak gust: –0.08 mph/decade (R²≈0.00) → flat Top 1% peak gust (P99): +0.98 mph/decade (R²≈0.05) → weak/noisy Quantity trends (frequency; percentage-points per decade) Computed as “of gust observations that exist, what % exceed threshold”: Hourly gust frequency: Gust ≥30 mph: +4.23 pp/decade (R²≈0.28) Gust ≥40 mph: +0.80 pp/decade (R²≈0.08) Peak-gust-within-hour frequency: Peak ≥40 mph: –1.48 pp/decade (R²≈0.03) → flat/noisy Peak ≥50 mph: +0.62 pp/decade (R²≈0.12) → weak/noisy Interpretation: In the most consistent era, the cleanest “signal” is more frequent ≥30 mph gusts (quantity), while the top 1% intensity is mostly noisy/flat. Sustained hourly speed looks basically flat. --- Your “Speed or quantity?” question — answered For sustained winds: neither intensity nor frequency screams “up.” It’s mostly flat in the consistent-era view. For gusts: the best-supported change is quantity (more ≥30 mph gusts), while “top 1% intensity” is not robust (too noisy + sensitive to measurement definition). If you want, I can tighten this even further by: using seasonal bins (DJF/MAM/JJA/SON) for gust thresholds (often cleaner than annual), and/or using percentiles computed from a fixed reference period (e.g., define “top 1%” using 2008–2014 and apply it to all years) so “top 1%” doesn’t move just because the distribution shifts.

So Sam Lilo did a ridiculous million winter simulation to try to quantify what Boston experienced that fabled 30 day stretch in 2015 when 90+ inches fell in 30 days. Reaching a conclusion it was a 1:26000 year event. I did similar for Harrisburg based upon 125 years data and 30,000 simulation years. Based on the analysis of the simulation data (max30_histogram_bins_0p25.csv) and the historical seasonal maxima calculated from the Harrisburg records, the Gamma Distribution remains the best-fitting mathematical model. 1. The Model: Gamma Distribution The Gamma distribution is ideal for modeling physical quantities that are always positive and exhibit a "heavy tail" (skewed towards high values), such as extreme snowfall events. Variables Defined: * x: The 30-day snowfall amount (in inches). * \alpha (Shape): Determines the fundamental shape and peak of the curve. * loc (Location): The shift/offset from zero. * \theta (Scale): Controls the "spread" or horizontal stretch of the distribution. * \Gamma(\alpha): The Gamma function (an extension of factorials for non-integers). Equation with Derived Coefficients: Using the simulation data for the fit: * * * 2. Goodness of Fit We used the Kolmogorov-Smirnov (KS) test to evaluate how well the model describes the data. A lower KS statistic (closer to 0) indicates a better fit. | Dataset | KS Statistic | P-Value | Interpretation | |---|---|---|---| | Simulation Data | 0.0155 | 1.05 \times 10^{-6} | Excellent Fit. The model follows the simulation counts almost perfectly across the entire range of values. | | Historical Observations | 0.1438 | 0.0097 | Moderate Fit. The model generalizes the history but over-predicts low-snow years and under-predicts the mid-range "typical" snowiest months. | 3. Analysis * Simulation vs. Model: The Gamma curve is a near-perfect approximation of the simulation data. It successfully captures the rapid rise in probability between 0 and 10 inches and the long, thin tail extending past 60 inches. * Historical Gap: As shown in the right-hand graph, the historical observations are more "clumped" than the model predicts. In reality, Harrisburg has a very strong peak of seasonal maxima between 15 and 25 inches. The model (derived from simulation) peaks slightly earlier (around 10 inches). * Extreme Tails: The simulation model is much "bolder" than the historical record. It suggests a non-zero probability of 30-day periods exceeding 80 inches, whereas the historical record (spanning ~126 years) has never surpassed ~51 inches. * Conclusion: The equation is a highly reliable model for the theoretical distribution of 30-day snowfall. However, if used to predict a typical winter in Harrisburg, it will slightly underestimate the "average" peak snow month while significantly overestimating the potential for unprecedented "megastorms."

Subject: 90 Years of Harrisburg (MDT) Hourly Weather — Full Deep Dive (1935–2025) Alright everyone, stuck at home in bed I went down the rabbit hole so you don’t have to. I pulled the entire hourly MDT dataset from 1935 through March 30, 2025 — roughly 701,600 hourly observations spanning just over 90 years. This wasn’t a daily summary skim. This was raw hourly temperature, dewpoint, precipitation, visibility, and related fields. Before I even looked at stats, I did cleanup and QC because raw long-term station data is messy: --- Data Cleaning & Methodology 1. File scope Period: Feb 1935 – Mar 2025 ~701,594 hourly bins Observations normalized to hourly resolution (multiple obs per hour consolidated) 2. QC steps Removed physically impossible dewpoints (e.g., below −80°F artifacts) Filtered obvious temperature spike errors (one 60°F+ 6-hour swing in 2013 was clearly a glitch) Precipitation analysis restricted to hours where precip reporting was valid (so “missing” ≠ “dry”) For daily metrics (high/low, freeze dates, heat streaks), only days with sufficient hourly coverage were used Snow depth largely unavailable in this dataset (only ~200 total depth entries), so snow retention metrics were excluded This gives us a dataset that is physically realistic and trend-consistent. --- The Results Absolute Extremes Coldest hour: −22°F (Jan 21, 1994 at 12:00) Hottest hour: 105°F (July 23, 1991 at 20:00) That’s a 127°F total observed range at MDT. --- The “Weather Whiplash” Award Largest temperature swings (QC’d): Largest 6-hour warm-up: +39.96°F (March 31, 1943) Largest 6-hour cool-down: −43.02°F (March 1, 1937) Classic Mid-Atlantic frontal violence. --- Longest Deep Freeze Continuous ≤32°F streak: 398 consecutive hours Jan 19 – Feb 4, 1961 ~16.6 straight days below freezing Runner-up: Dec 25, 2017 – Jan 9, 2018 (363 hours) So yes — modern winters can still lock in. --- Freeze–Thaw Chaos Index I counted crossings of 32°F in winter (Nov–Mar). Most chaotic winter: 1941 (188 crossings) Modern median winter: ~60 crossings That’s a real structural shift in winter volatility. --- Heat Wave Persistence (Daily-Based) Consecutive days with highs ≥90°F: Longest streak: 16 days (July 26 – Aug 10, 1983) Next longest: 15 days (July 1955) Hourly streaks don’t tell the real story because nights cool. Days do. --- The “Swamp Index” Defined as: Temp ≥90°F AND Dewpoint ≥70°F Total oppressive hours in record: 2,348 Top oppressive years: 1952 (92 hours) 1959 (87) 1949 (84) 1991 (83) Mid-century humidity was not subtle. --- Fog / Visibility Shift Hours with visibility ≤1 mile: Total: 22,368 hours ≤0.25 mile (“pea soup”): 4,860 hours By decade: 1940s–50s: ~5–6% of hours ≤1 mile 2000s–2020s: ~1.5–1.7% That is a massive drop. Possible contributors: Instrument changes Air pollution regulation Land use changes Reporting practices But the decline is statistically obvious. --- “Perfect Weather” Hours Defined as: 65–75°F Dewpoint 45–55°F No precip Visibility ≥10 miles Total perfect hours: 4,484 Best months by frequency: 1. September 2. June 3. May July is loud. September is elite. --- Precipitation Extremes Largest 1-hour precip: 4.27" (July 23, 2017) Wettest 24-hour day (reliable coverage): 16.29" (Oct 11, 2013) Wettest 72-hour total: 22.66" ending Sept 8, 2011 Those 72-hour numbers are hydrologically serious. --- Dry Spells Longest continuous dry streak (with reporting active): 286 hours Oct 20 – Nov 1, 2024 ~11.9 days Longest continuous rain streak: 33 hours (Oct 16–17, 2009) --- “Most Normal” vs “Most Weird” Year I computed daily mean deviations from long-term day-of-year climatology. Lowest RMSE (most “boring” year): 2019 Highest RMSE (most structurally weird year): 1967 1967 wasn’t just warm or cold — it was off-pattern. --- Structural Climate Signals (The Interesting Part) Comparing 1936–1959 vs 2000–2024: Diurnal Temperature Range Early period: 17.94°F average daily range Modern period: 16.36°F Change: −1.58°F Days and nights are less swingy now. Night vs Day Warming Mean daily minimum change: +2.64°F Mean daily maximum change: +1.07°F Nights warming more than days is a classic humidification / greenhouse signature. Dewpoint Drift +0.79°F increase in daily mean dewpoint Combine: Warmer nights Slightly higher dewpoints Reduced diurnal range That suggests a shift toward a more moisture-retentive boundary layer and fewer extreme radiational cooling setups. --- Growing Season Length Using freeze date methodology: Earliest first fall freeze: Oct 16, 1939 Latest first fall freeze: Nov 13, 2024 Longest growing season: 233 days (2024) Shortest: 158 days (1983) Typical: ~203 days The envelope is expanding. --- Big Takeaways 1. The 1940s–1960s were much foggier and had more freeze–thaw volatility. 2. The 1980s still dominate heat wave duration. 3. Extreme precipitation events are clustered in the 2000s–2010s. 4. Nights have warmed faster than days. 5. Diurnal range compression is measurable. 6. Dewpoints are nudging upward. 7. Growing season envelope has widened. This isn’t just “it’s warmer now.” It’s structural atmospheric behavior shifting. When looking at rainfall data I can tell hourly amounts are off. It seems to summing partial hour and hourly readings, basically double counting. See below Based on the weather data for Harrisburg (Middletown), the highest 3-day precipitation total on record is 15.11 inches. This historic rainfall occurred from June 21 to June 23, 1972, primarily due to the impact of Hurricane Agnes. The daily breakdown for that period was: * June 21, 1972: 5.81 inches * June 22, 1972: 9.13 inches * June 23, 1972: 0.17 inches * Total: 15.11 inches For comparison, the next highest 3-day total was 11.05 inches in September 2011, during the flooding from Tropical Storm Lee.

We might as well get the #drought moniker going. I fear this could be the year we truly bake under the vine come summer, with full water restrictions everywhere and the bit.

I want to make it known just how rare these past 19 days have been. KMDT has had snow on the ground since 1/25. Adding up snow depths we get 111" or an average of 5.84"; but never more than 9". When looking at the past In the last 126 years of data, this specific "steady but deep" condition has only occurred in 4 winter seasons: 1905 1925 1961 1968 Usually to get to 19 days requires a big boy storm.
