Human history is all about developing technology to adapt to our surroundings and then migrating when the technology can’t keep up anymore.

Seems like many of us on these boards are in the minority as to which type of weather we like the best. I know forums like this one originally started out as winter weather lover gathering spots. That’s why there has been so much resistance to the concept of climate change throughout the years. But even that has been shifting recently as the warming has become so obvious. The biggest population increases in this country have been in places that are subject to extreme heat, droughts, hurricanes, flooding, etc. So I am not sure if the migration patterns within this country will be sustainable over the long term with increasing extreme weather. People that I talk to can’t wait to move to places that don’t get any snow or cold and where they can wear their shorts all year. But I don’t think that they are taking into account how the extremes in those locations may make those areas harder to adapt to. I guess we’ll see if the future has people shifting back to cooler locations.

The comparison over the satellite era has been pretty consistent. Since we aren’t missing storms now that may have been missed before satellites. Those were called shorties that dissipated before they were detected. But there have been reanalysis papers done that figures out how many short lived storms out at sea may have been missed by shipping.

One station is often up a bit more than the others in our area. It really comes down to the prevailing winds. Essex county, NJ and Queens, NY seem to take turns being the warmest. Having our airports close to the water often leads to localalized warm spots since wind direction is so important. Last summer it was the bay breeze keeping Newark cooler. This year the flow pattern has kept LGA cooler. Jun 21….EWR….+3.5…..LGA…+2.2 Aug 20…EWR….+1.3…..LGA….+2.0 Jul 20….EWR….+2.6……LGA…..+3.7 Jun 20…EWR….+1.7……LGA….+2.5

Newark made it to 103°yesterday for a new all-time June monthly maximum temperature. This was matched by the new Corona, Queens micronet station. Several other stations reached 100° also. So Essex and Queens counties were the warmest around the area in June.

The whole area had a top 6 warmest June. The one exception was JFK with strong sea breezes with the ocean still cooler. Parts of New England like Boston and Portland had their warmest June. Since the 30 year climate normals were updated to incorporate the record warmth of the last 10 years, departures won’t be as relevant a metric. That’s why we need to incorporate the actual temperatures and rankings to get a full picture of the warmth.

Historic Pacific Northwest Heatwave of 2021
bluewave replied to donsutherland1's topic in Climate Change
The Dust Bowl was an early example of humans altering the Great Plains climate through land degradation. We had a big hand in the magnitude of the record heat. Now we are cooling the region through our farming practices. https://www.nature.com/articles/s41467-020-16676-w The severe drought of the 1930s Dust Bowl decade coincided with record-breaking summer heatwaves that contributed to the socio-economic and ecological disaster over North America’s Great Plains. It remains unresolved to what extent these exceptional heatwaves, hotter than in historically forced coupled climate model simulations, were forced by sea surface temperatures (SSTs) and exacerbated through human-induced deterioration of land cover. Here we show, using an atmospheric-only model, that anomalously warm North Atlantic SSTs enhance heatwave activity through an association with drier spring conditions resulting from weaker moisture transport. Model devegetation simulations, that represent the wide-spread exposure of bare soil in the 1930s, suggest human activity fueled stronger and more frequent heatwaves through greater evaporative drying in the warmer months. This study highlights the potential for the amplification of naturally occurring extreme events like droughts by vegetation feedbacks to create more extreme heatwaves in a warmer world. https://www.sciencemag.org/news/2018/02/america-s-corn-belt-making-its-own-weather The Great Plains of the central United States—the Corn Belt—is one of the most fertile regions on Earth, producing more than 10 billion bushels of corn each year. It’s also home to some mysterious weather: Whereas the rest of the world has warmed, the region’s summer temperatures have dropped as much as a full degree Celsius, and rainfall has increased up to 35%, the largest spike anywhere in the world. The culprit, according to a new study, isn’t greenhouse gas emissions or sea surface temperature—it’s the corn itself. This is the first time anyone has examined regional climate change in the central United States by directly comparing the influence of greenhouse gas emissions to agriculture, says Nathan Mueller, an earth systems scientist at the University of California (UC), Irvine, who was not involved with this study. It’s important to understand how agricultural activity can have “surprisingly strong” impacts on climate change, he says.- 323 replies

100° now at LGA with the more SW flow. 30 Jun 3:51 pm 100 65 32 SW

Those ground level stations are located in the local neighborhoods. The Corona Queens station has a high today so far of 101°. It’s avoiding the breeze of the water that is currently keeping LGA cooler.

We came close to the June all-time warmest 850 mb temperature on a 12z sounding today.

At least the day 15 EPS had the general theme of a ridge near the NW and NE correct. But we have seen how the magnitude of these ridges have been beating expectations. The models usually need to get to under 168 hrs to have a clue of how amplified the ridges will be. So the record breaking nature of this event really snuck up on the models in their better range.

The new NYC micronet is proving to be a valuable resource. We continue to see other stations in Queens with warmer high temperatures than LGA. The lows all stayed at 80° or above. LGA…………….…….98…81 Astoria………….….99…81 Corona……………..100..80 Queensbridge…..99…80

Historic Pacific Northwest Heatwave of 2021
bluewave replied to donsutherland1's topic in Climate Change
Christopher Burt also did an analysis on the Oregon record high temperature. https://web.archive.org/web/20151012131142/http://www.wunderground.com/blog/weatherhistorian/comment.html?entrynum=19 OREGON RECORD HIGH TEMPERATUREThe record high for the state of Oregon has long been accepted as 119°F at Pendleton on Aug. 10, 1898. The NCDC site also mentions a similar reading at Prineville on July 29, 1898). First off, the Prineville reading can be dismissed immediately as unbelievable. Prineville is located in the center of the state near Redmond and Bend at an altitude of 2,860’. It is not a particularly warm location and its hottest temperature in modern records is just 107°F. There were many suspicious temperatures from Prineville during the summer of 1898.The Pendleton reading is more difficult to dismiss. Pendleton is located on a river plain about 30 miles south of the Columbia River. This valley is the hottest area in the state with 100°F+ temperatures common every summer. An undisputed temperature of 117°F has been measured at nearby Umatilla, Oregon on July 27, 1939. The problem with the Pendleton reading is that it was an estimated not measured reading and it would seem that estimated temperatures should probably not be considered official, especially for something as significant as a state weather record.According to the newspaper East Oregonian a report on Aug. 11, 1898 stated “…the government thermometer is only calculated to 115°, so that the 4° indicated above that had to be measured (estimated) by an observer.” This story is recounted in The Oregon Weather Book: A State of Extremes (p.64) by George H. Taylor and Raymond R. Hatton, Oregon State University Press, 1999.- 323 replies
