That period through the 3/2010 Noreaster that knocked hundreds of trees down with hurricane force winds was crazy. That was windier than Irene. 1 Link to comment Share on other sites More sharing options...
the_other_guy Posted February 25 Share Posted February 25 3 hours ago, bluewave said: That’s for sure. Another case of the warm minimums driving the departures. Pretty wild to see Upstate NY with low temperature departures for the whole winter in the +7 +11 range above the much warmer 91-20 climate normals. The NE warming is alarming and completely off any chart or estimate possible. Unless something changes in this trend, winter as we know it in Adirondacks is changed. It will be non existent here. No climatologist had this depth of warming in any analysis. This seems to be a radical regional effect of Indian/Pacific Ocean warming. Someone could write a whole thesis on why this is happening and where it is going 1 Link to comment Share on other sites More sharing options...

bluewave Posted February 25 Share Posted February 25 Each new El Niño boosts the temperatures to a higher baseline. The 09-10 El Niño marked the beginning of a much warmer summer pattern which continues to this day. The 15-16 El Niño coincided with a shift to much warmer winters. The winter warming shift was of a higher magnitude than we have seen relative to the previous means than the summers. Now the global temperature jump with the 23-24 El Niño was even higher than the 15-16 super El Niño even though it wasn’t as strong. So it will be interesting to see what happens to our temperatures and weather patterns in coming years at this even higher temperature baseline. 2 Link to comment Share on other sites More sharing options...

I would thing the increase in temperatures is driving the el Nino to become warmer each year. The El nino just distributes (or concentrates) the wealth? Because if the El Nino is actually causing the increase in warmth and not as much the greenhouse gases, do we have to re-assess? 2 Link to comment Share on other sites More sharing options...

donsutherland1 Posted February 25 Share Posted February 25 Milder air will overspread the region tomorrow. Afterward, temperatures will remain generally above normal through the remainder of February. The potential exists for the closing days of February to wind up much warmer than normal. Little or no additional snowfall is likely in the New York City or Philadelphia areas through the remainder of February. March will likely begin with generally unseasonable warmth through the first 7-10 days of the month. No significant snowfall appears likely in the northern Middle Atlantic region during that time. Overall, March will likely be warmer than normal. The ENSO Region 1+2 anomaly was +1.1°C and the Region 3.4 anomaly was +1.5°C for the week centered around February 14. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.95°C and the ENSO Region 3.4 anomaly has averaged +1.72°C. A basinwide El Niño event is ongoing. The ongoing El Niño event will continue to fade during March. Neutral conditions could develop during the spring. The SOI was +2.83 today. The preliminary Arctic Oscillation (AO) was +2.071 today. On February 23 the MJO was in Phase 6 at an amplitude of 0.383 (RMM). The February 22-adjusted amplitude was 0.343 (RMM). Based on sensitivity analysis applied to the latest guidance, there is an implied near 100% probability that New York City will have a warmer than normal February (1991-2020 normal). February will likely finish with a mean temperature near 39.9° (4.0° above normal). Winter 2023-2024 is on course to finish with a seasonal mean temperature of 40.4°-40.6°. That would rank the current winter among the ten warmest on record in New York City. It would also mark the second time when two consecutive winters have ranked among the top ten in terms of warmth. Winters 2015-2016 and 2016-2017 are currently the only two such winters to rank among the ten warmest on record. Winters 2022-2023 and 2023-2024 will become the first time on record that New York City has seen two consecutive winters with 40.0° or above mean temperatures. Since 1869, there have been six winters with a mean temperature of 40.0° or above. Five have occurred since 2000. 1 1 Link to comment Share on other sites More sharing options...

Yeah, the El Niño releases the excess heat building up in the oceans as the climate warms. So the El Niño itself isn’t causing the warming. If we had a stable climate like in the late 1800s, the global temperatures would quickly drop in few years like after the super El Niño like in 1877-1878. But as the climate continues to warm, each El Niño year sees a new annual jump. So it’s mostly a modulator of which years set new global temperature records between the neutral or La Nina years. I guess we have been lucky that the pace of the summer warming since 2010 hasn’t been as high as the winter warming since 2015. 1 3 Link to comment Share on other sites More sharing options...

The South largely had its hottest summer on record last year. One summer that ridge will extend north and we'll get a westerly downslope major heat wave again. We've been lucky in a sense that the Bermuda High extends so much further north now that it drives southerly winds not westerly-increasing the humidity but not really the high temps. But that also guides hurricanes up the coast and not recurve out to sea. 3 Link to comment Share on other sites More sharing options...

The low took a track due north then NW and the trough negatively tilted fast then closed off. East of the Van Wyck was on the wrong side of the initial heavy precip burst until the heights started crashing to the east and the cold enough air could make headway east onto LI. I took the train into the city that day and remember it turning from heavy rain to heavy snow just east of Jamaica and then blinding blizzard in Manhattan. In the afternoon when I got home the snow was starting in Nassau and starting to accumulate in Long Beach, and that night winds were fierce with the snow. Very impressive storm, 2 weeks before the big 3/13/10 monster. 1 Link to comment Share on other sites More sharing options...

It's interesting that 2016 was tied with 1983 at EWR, both were super el ninos with big snowstorms and 1983 used to be the summer with the most 90 degree days prior to the 90s (and at JFK prior to 2010), but 2016 wasn't that high on the list for 90 degree days at either NYC or JFK was it? What was that year when JFK doubled the 70 degree dew point days record-- 2016? I remember they had like 42 of them, beating 1983's record of 21? Too bad they didn't have nearly as many 90 degree days in 2016 as they had in 1983! 1 Link to comment Share on other sites More sharing options...

Didn't Newark hit 106 that summer? That was the year with the brutal soaking and windy March storm which uprooted as many trees as a hurricane. All followed by 2011 and 2012 with Irene, the earthquake, and capped off by Sandy, itself ending with a significant early November snow. We lived in interesting weather times. 1 Link to comment Share on other sites More sharing options...

It's interesting that 2016 was tied with 1983 at EWR, both were super el ninos with big snowstorms and 1983 used to be the summer with the most 90 degree days prior to the 90s (and at JFK prior to 2010), but 2016 wasn't that high on the list for 90 degree days at either NYC or JFK was it? What was that year when JFK doubled the 70 degree dew point days record-- 2016? I remember they had like 42 of them, beating 1983's record of 21? Too bad they didn't have nearly as many 90 degree days in 2016 as they had in 1983! Taking the Central Park temperatures under the trees since the new ASOS was installed back in the 90s created an artificial cooling of daytime highs during the the warm season. When they measured the temperatures away from the trees prior to the 1990s, NYC had more 90° days than LGA. So the decline in 90° days from 30 years before and after the new ASOS was installed is an artifact of the poor sitting and not a reflection of the actual temperatures in Central Park which used to be warmer than LGA. All our other stations away from the sea breeze have seen a steep increase in 90° days over this period. https://www.nytimes.com/1977/07/22/archives/vandals-in-central-park-forcing-weather-service-to-seek-new-site.html When the devices at the castle are not functioning, the Weather Service substitutes readings from La Guardia Airport. But Mr. Gibson said those readings do not really reflect conditions in the city, because they may be several degrees cooler in summer or warmer in winter than those in Central Park. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=74&network=NJCLIMATE&station=NJTNBR&season=all&dir=above&var=high&threshold=90&year=1960&_r=t&dpi=100&_fmt=png 3 Link to comment Share on other sites More sharing options...
