July is just beginning.
Phoenix experienced The hottest one on record In July 2020 with reliable records go back to 1895. Now, the warmest city in the United States broke another record: on Sunday, the Phoenix hit a high temperature of at least 110 degrees Fahrenheit for the 34th time this year, with a hot August was still in the future. The previous record of 33 days in 2011.
This continued heating of the trends, as many of the extreme environmental events of today, is stoked by a powerful weather events, increased human-caused climate change.
“This is a dramatic event,”said Jeff Weber, research meteorologist, University Corporation for Atmospheric Research.
Large Drive in the 110F days is a lack of humidity and rainfall, the General swept into the southwest beginning in mid-July, the occurrence known as the North American monsoon. In the rainy season, which will continue into September, heavy rain from the South to moisture, clouds and rain to the American Southwest, cooling the area.
However, the rainy season has been mostly absent this year. This case, combined with the continued warming of the South-West, a hot record.
“You have an extreme lack of a rainy season this year, superimposed on a warmer trend,”said Daniel Swain, a climate scientist at UCLA and the National Center for Atmospheric Research.
Arizona experienced a The second most popular May through July In the recording this year, and overall, the average temperature in the Southwest has already increased by at least 1. 6F since the early 1900’s. This heating is exacerbated by extreme drought in the region, prompting Western countries to cut their water use reduced from the Colorado River.
There is no one rainy season of this year, keep your distance, by a mass of high air pressure area(called a ridge), almost no clouds obscured the sun and the ground becomes dry. Therefore, the smaller the sun’s scorching heat to achieve evaporation of moisture from the ground. On the contrary, the energy of the sun’s direct heating surface, unforgiving.
“It’s just the chef,”said Weber, noting that as a former Phoenix residential meteorologist, he used to call this unpleasant weather mode”heat ridge of death.”
Phoenix has increased the problem, expanding the already hot air, some called the”urban heat island effect”。 The city’s main roads, buildings and concrete absorb heat, and then reemit it into the atmosphere. “Today, Phoenix is a large sprawling city with a lot of concrete,”noted Swain.
However, it is important that the heat is universal. Temperatures may be magnified in the development of the Phoenix, but they are happening all over the desert.
“It is just the chef.”
“This is not something that is super-localized,”said Swain. “This is something that has already occurred across a large part of the southwest.”
The lack of rain this year will have a huge impact. Arizona gets a significant amount of annual rainfall of the rainy season, explained Weber. Therefore, a dry summer will mean that next year is also drier.
“This will have a lasting effect,”said Weber. “It’s all about the water.”
The National Weather Service requires a high point between the F112 to 116F under the desert later this week, Institutions that are”abnormal” For this time of year.
This may be harmful, if not dangerous, for the residents of the overheating of the community. In extreme weather events in the United States, heat is a deadly event.
Yes, the southwest region, particularly the low-lying valley, the natural heat in the spring and summer. But now, an unusual consistency of the scorching 110F(or higher)temperature is the fight against the desert.
It is difficult in the well-known tenacity of desert life.
“Even in desert plants has been difficult to endure this drought and heat,”said Weber pointed out, withered and dead plants and animals after such a long time of the thermal event. “It’s very devastating.”
