Temperatures in Death Valley, California reached 122 degrees Fahrenheit (50 degrees Celsius) on Tuesday (June 15). This is below the record high for this spot, which is the lowest in North America but more than 10 degrees above average. This time of year is hot.
The roasting temperature was part of a wider heat wave this week across the southwestern and western United States.Tuesday, denver Reached a maximum temperature of 101 degrees Fahrenheit (38 C), the earliest year since 2013 when temperatures exceeded 100 F (37.8 C).I saw it on the same day Hot and humid 105F In Billings, Montana (40.6 C), it was the record for the day, and in Sheridan, Wyoming, it was a record 107 F (41.7 C), tied to previous state records. Salt Lake City also tied the highest temperature ever recorded at 107 degrees Fahrenheit on Tuesday.Southern California broke Multiple heat records, Palm Springs wilts at high temperatures of 119 F (48.3 C). Meanwhile, Phoenix, Arizona, achieved a record temperature of 115 F (46.1 C) in 1974.
Death Valley is known for its withering heat. The desert is below sea level, but surrounded by steep mountains. According to the National Park Service (NPS). Sunlight warms the dry desert floor and heat remains trapped in the surrounding rocks and soil. The highest temperature record in the world was set on July 10, 1913 at Furnace Creek in Death Valley. That day, Furnace Creek reached 134 F (57 C).
Contributing to the current heat is a weather pattern known as the “heat dome.” According to CNNThe high-pressure ridges of the western United States trap hot air near the surface, pushing away potential precipitation. The clear sky also heats things up in the dome.And what’s worse, much of the west is now deep Drought..
Drought means that the air and soil are low in water. Karen McKinnon, a climate scientist at the University of California, Los Angeles, says that during heavy rains, a significant portion of solar energy is used to heat and evaporate this water. During the dry season, the temperature rises freely because there is no such wet “heat sink”.
“All that heat comes in, but the soil is very dry,” McKinnon told Live Science. “Therefore, much of that heat raises the temperature instead of evaporating the water.”
According to the NPS, Death Valley is not surprisingly hot, but the average temperature in June is usually closer to 110 F (43.3 C) than 120 F (48.9 C). The average maximum temperature in July is 116F (46.7 C).
Temperatures from Death Valley to Friday are expected to be at or above the highest temperatures on Tuesday.Ann Excessive heat warning Until Saturday, it takes place in most of California and Arizona.
