by New York (AP)-A intensive and almost historical weather pattern is the cooking of a lot of America under a dangerous heat dome this week with three-digit temperatures in places that have not been so hot for more than a decade.
The heat wave is particularly threatening because at the beginning of summer they meet cities like Boston, New York and Philadelphia when people did not adapt their bodies to the barbecue conditions, several meteorologists said. The dome of the high pressure, which parks over the eastern United States, captures the hot air from the southwest, which has already stopped in the middle west.
An important measurement of the strength of the high pressure broke out on Monday and was the third highest reading for any time that caused an “almost historical” heat wave, said private meteorologist Ryan Maue, a former scientist of National Oceanic and Atmospheric Administration. The worst heat is likely to reach its climax on Tuesday in the northeast of the cities, according to forecast.
“It gets hot like an air fryer,” said Maue. “This is a three-day heat that the urban residents who are most susceptible to oppression heat waves are most susceptible.”
A heat dome occurs when a large area of the high pressure in the upper atmosphere acts as a reservoir and heats heat and humidity. A heat wave is the persistence of the heat, usually three days or more, with unusually hot temperatures.
Where the heat is the worst
Almost three quarters of the population of the country of the country-245 million people on Monday with 90 degrees Fahrenheit (approx. 32 Celsius) or higher temperatures and 33 million people, almost 10% of the country, organized a blasty heat of 100 degrees (approx. 38 Celsius) on Tuesday, said Maue. The government’s website showed the highest risk of heat in the swath of Chicago via Pittsburgh and North Carolina to New York.
This three-digit air temperatures with the feeling that is even worse in places in which it is unusual due to air humidity. New York has not seen 100 degrees since 2011, and Philadelphia, which is predicted that he has consecutive three -digit days, has not reached this brand since 2012, said the climate, Bernadette Woods Placky.
In the city center of Baltimore, the temperatures rose to the high 90s until early Monday afternoon and brought dozens of people to cool off in the St. Vincent de Paul resource center. A few blocks of houses closed the city’s historic food hall when the air conditioning of the building broke.
The heat forced the cancellation of events in West Baltimore, said Eric Davis Sr., who spends most of his days there to work in a baseball field.
“You cannot have children who get heat stroke,” he said. “It’s just too hot today.”
The Noaa meteorologist David Roth said it took time to get used to the summer heat, and this heat dome could be a shock for some.
“You speak of some places that could be 40 degrees warmer than last week. So that’s a big deal,” he said.
Climate change makes earth warmer
The heat is part of the long -term warming of the earth. According to NOAA data, the Summer in the United States are 2.4 degrees (1.3 degrees Celsius) in the USA than 50 years ago. The climate change caused by humans has made this heat wave three times more than without burning coal, oil and gas, the non -profit climate of climate science calculated, with computer simulations comparing the current weather with a fictional world without industrial greenhouse gases.
An important question is how much air humidity the discomfort and the risk of heat will contribute.
Maue predicts dry air, which can be one or two or three hotter than predicted by NOAA, but more comfortable. Other meteorologists expected worse: sticky, moist and even more dangerous.
“The ‘big thing’ will be equipped with the wet moisture with the wet late spring duties,” said Jason Furtado, Professor of Meteorology at the University of Oklahoma. “The high -pressure range enables a lot of evaporation from the wet areas from the wet terrain and regionally, which increases the heat indices quite a bit.”
Woods Placky expects taup points in the 70s, an essential measure of humidity. This is almost tropical, and some places approach a dew point of 80 – a level Woods Said feels like “they are in a swimming pool” and “The atmosphere absorbs them”.
If this heat were later in summer, it may not be so dangerous because the human body can adjust to the seasonally warmer temperatures, but this is said within days after the solstice, Woods Tacky and others.
“It will be a shock for the system,” she said.
