weatherpruf Posted April 26, 2022 Share Posted April 26, 2022 Some speculation that the losses of white cedar in S Jersey are due to over saturation from precip heavy storms. Some speculation as well that local fisheries like the winter flounder have been affected somewhat by warmer waters ( though overfishing played a role as well; for reasons that are unclear some environmental groups are reluctant to point fingers at commercial fisheries, which are a big contributor to plastic waste in the oceans, as much as 50% )and there are regular reports of southern fish species showing up in our local waters, like the poisonous southern puffer, cobia, and Spanish mackerel.

bluewave Posted May 3, 2022 Share Posted May 3, 2022 Liberty Bell Is there any way to project where Central Park would rank on these lists if their equipment was sited better? The Central Park equipment was out in the sun and away from the deep shade during the 1951-1980 climate era. So we can compare how the high temperatures during the summer have changed between EWR, NYC, and LGA since then. The tree growth over the equipment has trimmed 2° off the NYC summer high temperatures relative to EWR and LGA. This has resulted in many lost recent heat records for NYC as the record warmth dramatically increased since 2010. Central Park should be averaging 10 more annual 90° days instead of just 1 if it was out in a grassy clearing away from the deep shade and cooling foliage. 2010-2021 summer high temperature warming over 1951-1980 NYC 1951-1980……83.0……2010-2021….83.5…..+0.5….should be closer to 85.5 or +2.5 away from the shade EWR…83.4…..85.7…+2.3 LGA….82.0…..84.6...+2.6 90° days change NYC….18……19……+1…should be +10 and 28 days a year of 90° EWR….23....33…….+10 LGA…..15…..26…….+11 4 Link to comment Share on other sites More sharing options...

I'd thought that site alterations would be addressed by the NWS quality control, but clearly that is not the case. Yet this seems to show a rather larger impact than the widely discussed Time of Observation bias. Does it just get treated as a local issue without broader significance?

Maybe one day a high enough ranking NWS official will find this thread and look at what is going on. We seldom see meteorologists from the local Upton NWS office join in these threads. But other local forums seem to have NWS meteorologists checking in. Walt is great but he was from Mt. Holly and Boston. So we probably need a local office member to take interest in this issue. They probably don’t even realize how far the Central Park ASOS has drifted away from the more accurate readings that we used to get before the new station was installed in the mid 90s. We can see how many top 10 years there were for 90° days at EWR and LGA since 2010. But notice how most of the NYC highest totals were from before the the time of new weather station in the mid 90s. If we add the 9 missing annual days to these totals, then they are more in agreement with LGA and EWR like they used to be before the mid 90s.

At this point I dont see any solutions outside of manually relocating the equipment-- do you? It's so obvious there is no way they don't know what's going on. On a different subject-- Chris, can you list JFK's top 90 degree day years? I think they would be 2010, 2002 and 1983? 1944 must have been an amazing summer- big heat and capped off with the Great Atlantic Hurricane! By the way did you notice that even after adding those extra 90 degree days, 2010 still stands out way ahead of every other year and no other recent year is above 7th at Central Park?

I put out this data and analysis for everyone to freely share. You can add the post below to an email and send it along to him. The Central Park equipment was out in the sun and away from the deep shade during the 1951-1980 climate era. So we can compare how the high temperatures during the summer have changed between EWR, NYC, and LGA since then. The tree growth over the equipment has trimmed 2° off the NYC summer high temperatures relative to EWR and LGA. This has resulted in many lost recent heat records for NYC as the record warmth dramatically increased since 2010.

I must confess, without thinking of the proper etiquette, I did attach a screen shot of your post in my letter to Mr Boutin. I have attached two screen shots to show my rather wordy letter. I even mentioned how some of our members had volunteered to do the pruning. I could just imagine Will showing up with a chain saw in a hockey mask. The way things are going lately, he might not even stand out. Thank you BW for the okay on the good to share forum post data. Mr. Boutin gave me the office number and a cell phone number. Perhaps, if he ever has the time, he may peruse the forums. As always, here’s hoping …. 1 1 Link to comment Share on other sites More sharing options...

Trim or chop down the excess foliage! What exactly is keeping them from doing that? You would have to ask them that question. We don’t see anyone from the Upton posting on this forum. Albany just corrected their cold bias. To the Editor: If you have been following the latest monthly temperature trends, as provided by the National Weather Service, you might have noticed that we have had five months with below normal average temperatures, and only two that have been above this year (January and March). In fact, if you go back to last year, you might have noticed a “cooling” beginning in August, as three out of the six last months of 2020 finished below normal. This was happening at the same time that many of the same months were close to record high levels worldwide. The National Weather Service issued its new 30-year climate averages in July 2021 (including the average temperature of the years 1991 to to 2020). This new set of averages indicated many of our monthly averages have warmed nearly a degree compared to the 1981-2010 averages. This would account for some of the cooler departures in recent months. A persistent trough has settled into the region for much of this time, accounting for some local cooling. However, a much bigger concern is the actual thermometer located at the Albany International Airport. In July 2020, it was discovered that it had been running a degree too warm. The sensor was replaced and it was immediately noted it was running about three degrees too low (cool). It took until mid-October 2020 for it to be replaced, but alas, the new replacement still appears to still be running at least two degrees too low. There are no signs of it being replaced anytime soon, at least before the winter. A thermometer is a basic instrument, originally measured by the response of mercury or alcohol in a tube, and can be calibrated quite accurately. The National Weather Service has a more complex one, via an instrument called Automated Surface Observing System. It is well aspirated to prevent any “solar spikes” that many homemade thermometers might have if they are not located in a north position facing away from any sun. The instrument is required to be at least five feet off the ground to avoid any excessive surface heating that can happen near asphalt and other heat-absorbing materials. The thermometer sensor is part of a complex computerized system that also records wind speed, barometric pressure, and precipitation, which is issued automatically with initially no human intervention. A weather observer or traffic controller is required to be on duty at the airport to quality control the data that is disseminated. One would think the National Weather Service, being the steward of accurate weather detail, would seek to have an accurate thermometer. We all have heard that a global average warming of just 1.5C (about 2.5F) could wreak havoc on our planet. So, if the thermometer at the Albany International Airport is measuring 2.5 degrees too low, as I believe it is, this cool bias reading might mask any significant warming. However, according to the National Weather Service from the Silver Spring headquarters, the number-one client the Automated Surface Observing System thermometer is tailored for, would be the aviation community. The National Weather Service claims it relies on many volunteers for climate data for climate information, collectively called the Cooperative Observer Program or COOP. Assuming that is the case, an accurate thermometer is just as critical to the aviation industry. If the actual temperature is 34 F, but the Automated Surface Observing System thermometer records a temperature of 32 F, the pilot might have to be concerned about freezing rain versus liquid rain, which makes a huge operational impact. Also, the National Weather Service, both locally and at the higher end, realize there is a two- to three-degree cool bias, but argue the sensor itself is not to blame. My question to them: Then what is it? So far, there has been no answer. How do we know the thermometer has such a cool bias? You might have seen our local TV meteorologists use the Pine Bush temperature readings instead of the airport for a more representative temperature. I personally have a Davis thermometer myself, and have been keeping track of high and low temperatures for years. I live in the southwestern portion of Albany, away from the city heat island. I am on top of a small hill so my overnight lows usually ran about a degree or so warmer than the airport. However, my high temperatures were usually within a degree of the airport’s temperature until July 18, 2020, the day the thermometer was changed at the airport. From that point on, with a few noted exceptions, my thermometer has been consistently running 2 to 3 degrees warmer than the airport, the same thermometer I have had for years. My thermometer’s readings are much closer to the Pine Bush’s for high temperatures, and to many of my friends’ thermometers. If you look at monthly temperatures at Pittsfield and Glens Falls, in the past months, they have been very close to the airport. In the past, both places would usually run a mean temperature (combined high and low temperature) closer to 3 degrees lower than the Albany International Airport). Perhaps the worst part of all this, is that our monthly records with this known cool bias, keep going out to the world and would suggest our climate is locally cooling, when really it is not. The folks at the local National Weather Service in Albany are not to blame. They have done all they can to inform the higher officials of the problem. I suggest you call your local Congress member and hopefully they can put pressure on the higher officials of National Weather Service to change the thermometer before further damage can be done to the climate records and have a reliable accurate temperature sensor. Hugh Johnson Albany Editor’s note: Hugh Johnson, now retired, used to work for the National Weather Service. Joe Villani, a meteorologist at the Albany office of the National Weather Service, confirmed for The Enterprise that the thermometer at the Albany International Airport is several degrees off. “We’re definitely aware of it ….,” he said. “People at National Weather Service headquarters are looking into resolving it.” Villani said it can take time to diagnose problems with equipment invented in the 1990s. It was noted in July 2020, that the thermometer was running too cool, he said, so it was replaced last October but continues to run too cool.
