A couple of new climate studies indicate the severity of strong storms that are extremists and other disruptions that affect the East Coast of North America on a hot planet.
Noresters usually built about 100 miles from the east coast between North Carolina and Massachusetts, often when the cool air from Canada is hot, moist on the Gulf Waters. Contradictory air masses can begin to rotate with the jet stream, and fuel the storms that can cause harmful winds, coastal floods and severe, disrupting snow.
Michael Mann, a climate scientist at the University of Pennsylvania, said July 14, said Michael Mann, a climate scientist at the University of Pennsylvania, saying that the strongest Noreshters were already significantly sharp and raining. The action of the National Academy of Sciences.
In a 2022 study, a similar trend of severity for the Atlantic storms showed a similar trend and causing the killing of Europe, and that the storms are moving north to the north, which is likely to pose a higher risk to the unintended areas.
Mann said that the strongest nostrils have been fueled by the intensity and the rise in rainfall rates, potentially increasing marine temperatures and increasing heat of heat environment.
“There are two reasons for seeing extremely severe naresters.” From the point of view of the effect, they do the most damage, including coastal cuts, destruction and paralyzed snowfall, said Mann via email. In 1962, the Ash Buddhist storm, with 84 miles per hour, is an excellent example. In today’s dollar, he lost $ 21 billion. “
And just last February, at the time, a classic Norester described it as a “bomb storm”, which had dropped several feet of snow on parts of Virginia and North Carolina, and flooded floods in parts of Massachusetts Coast, East Long Island and Jersey coast.
Mann said that the strongest nostrils have been fueled by the intensity and the rise in rainfall rates, potentially increasing marine temperatures and increasing heat of heat environment.
Researchers, along with cautious revenue of the historic climate conditions around the storms, detected 900 naresters in 1940, including perfect storms in 1991, a storm of storm in 1993, and Sun Megden in 2010.
“In extremely strong storms, the wind speed has increased by about 5.4 percent from 69 to 71 miles per hour, but since destructive capacity operates with the wind speed with cubes, it is about 17 percent in destructive capabilities.”
Overall, he added, many research suggests that additional heat in the Arctic, which reduces temperature contradictions between high latitude and medium -sized, will lead to low storms as a whole, but the focus of the devastating abilities to accelerate the nosisters.
Compared to other types of storms, Noreshters eat more than the heat of the ocean, which lasts considerably in the winter, “so the storms that can make the barrier in the past have the potential to be stronger than that.” “Although we do not see any evidence of the increasing severity for the ‘average’ Norester, the strongest is becoming stronger.”
“How is my interest in these storms, and how they are affecting the climate change, has been affected by two personal experiences,” he said in March 1993, noting the “Century Hurricane”, which caused 270 deaths and $ 12.2 billion in 26 states, according to the national and environmental administration.
Mann said that the storm interrupted a spring break in Florida, where the temperature in St. Augustine dropped from the 70s to the 40s to a few hours.
“We drove the Okinok swamp at the end of that day and it was snowing,” Mann said. “Then we stopped in southern Georgia for the night and the temperature fell by the mid -20s. We were frozen. I will never forget it.”
“The strongest Noreshters category 1 and 2 hurricanes can have the effects, which have large areas of the area.”
He said he remembers Snow Magden, another notorious, Norester, since February 2010, because an American senator who rejects science, which proves warming because of human beings, uses the opportunity to build an opportunity that he called Eaglo in an attempt to doubt the climate science. At the same time, Mann said he was caught in a hotel room for three days in which several feet of snow stopped most of the roads in Pennsylvania.
Since such hurricanes are stronger in the world of warmth, Anthony Brooklyni, an environmental scientist at Rotors University, said that it was not involved in this new research, but also researching Noreshters, “It would be important to remember that the strongest Noreshors category 1 and 2 hurricanes have a major effect.”
Along with the surface surface along the east coast, Brooklyti added that Noreshters “would cause more coastal floods without any change in the severity of the storm.”
He said that the possibility of rising thermal energy from the seas of heat is moving towards strong nostrils, and there may be widespread changes in the maritime and winds that could change the tracks of the narates, which could potentially create unexpected risks in new areas.
New research does not mean that the temperature is cooling, but that the air is still made up of the Arctic in the winter, which will still make the path to the South, which may appear more often in the unexpected regions, or in the abnormal climatic extremes that can damage the crops.
Arctic connection
Judah Cohen, a climate expert, said in an email interview that the widespread changes in the United States and the extreme of the cold weather in the United States and the extreme of the winter season include the rapid heat of the Arctic region. Cohen, a scientist at MIT and the director of climate research, published a study on July 11, with environmental and environmental research. Science development Which reinforces the evidence of climate contact.
“As far as it is concerned, the new thesis is” preaching the coer, “Cohen said, as the results are in accordance with their own research, which shows that” Arctic changes can lead to episodes, including severe cold and disrupting snow in the east of the United States. “
The temperature contradictions between the Arctic and the middle are one of the major forces that create key winds at various heights like Jet Stream and Polar Vertics, and transmits the weather system around the northern hemisphere.
In recent years, Cohen’s work has shown that the rapid heat of the Arctic “spread” like rapid heat, such as increasing round rubber bands – in positions that allow cold polar air to the south more frequently.
He noted that in March 1993 and January 2018, two recent Noreshters, who were specially nominated in a new article by Main and his colleagues, presented during the spread of polar vertex. He said, the new thesis provides a medal for possible reasons but does not set any purpose. “
“For the first time, the spread of polar vertex is associated with extremely cold and heavy snowfall in East America,” he said.
Often the polar flows into a rigid coil around the north, which contains arctic air, but the study of cohen, and other research, suggests the trend of spreading more frequent polar bells and the effects of cold winds and storm effects. New research helps to explain regional “winter cooling trends over the past two and a half decades and the growing number of heavy snowfall in East America,” he said.
