In July, temperatures in Alaska and parts of the west hit record highs.
According to data released by the National Oceanic and Atmospheric Administration on Tuesday, these hot spots stood out among 48 states in July, the hottest month on record 10, surpassing the country's second hottest year so far. Three states had the hottest year this year, and several states ranked second or third.
Although weather patterns have a great influence on the monthly temperature-as the cool weather in early August shows-the overall warming of the earth is making the possibility of a record less hot. In fact, according to Guy Walton, a meteorologist, the highest daily record in July was four times the lowest in history, and he used the data of the National Oceanic and Atmospheric Administration (NOAA) to record such continuous changes.
Alaska's recorded heat drops along the northern slope, which is located above the Arctic Circle and is the center of the state's interior.
Rick Toman, Alaska Climate Science and Service Manager of the National Weather Service, said that a lot of "heat" can be attributed to "the early loss of sea ice", which usually adheres to the coast until August and keeps the temperature at a low level. There is almost no sea ice within 200 miles of Alaska.
The city suffers from the high temperature in summer. Climate change will worsen the history of global warming. In just 35 seconds at the midpoint, 20 17 was the second hottest year on record.
After the sea ice disappeared in early years, the storm brought warm air from the south, pushing the average temperature in Barrow to 46 degrees Fahrenheit in July. Although it doesn't sound like summer weather to other parts of the country, it is 5 degrees Fahrenheit higher than the long-term average temperature of a city at the same latitude in the middle of the Greenland ice sheet.
Toman said that in the interior of the state, there was no obvious heat wave this month, but there were no cool days because there was no cloudy and rainy weather. On the contrary, the warmth of "tempering day after day" this month,
Betis, Tanana and mcgrath not only had the warmest July, but also the warmest month on record. The average temperature in the first two towns is 5 degrees Fahrenheit higher than normal, while the average temperature in mcgrath is 3.7 degrees Fahrenheit higher than normal. Fairbanks has the fourth hottest July on record. July is already the third hottest in the state.
Toman said that in the next few months, the north slope will remain warm because the sea ice will disappear until it starts to freeze again in autumn.
In the lower part of 48 Bakersfield, California. Reno and Salt Lake City also experienced the hottest July on record, breaking several daily high temperature records in the region, because the high pressure ridge helped the temperature soar. The hot and dry weather also led to the outbreak of wildfire, which quickly spread to the whole area.
Miami not only maintains a record high temperature in July, but also in any month. Driven by the number of days above 90 degrees Fahrenheit (every day of the month, but the last day is so hot or hotter) and the fact that the temperature stays extremely warm overnight,
Death Valley, which is already famous for its extreme heat, reached a new level in July. The Capital Meteorological Group reported that the monthly average temperature was 107.4 degrees Fahrenheit. Once again, the lowest temperature at night becomes a major factor, because the temperature there will never be lower than 89 degrees Fahrenheit on any night of the month.
The temperature of three nights is actually between Fahrenheit 102 and Fahrenheit 103. Brian bretzen
