According to news reports, temperatures in the deserts of California have reached 130 degrees Fahrenheit (54.4 degrees Celsius), and this weekend isn’t just a morbid name.
This is comparable to the hottest temperature ever confirmed on Earth since mercury reached 131 F (55 C) in Kebili, Tunisia on July 7, 1931. The Washington Post reported.. On July 10, 1913, even hotter 134 F (56.7 C) was recorded at Furnace Creek in Death Valley (then called Greenland Ranch). According to Guinness World Records, Some climate scientists say the reading was not verified, Post said.
Rewinding almost a year ago on August 16, Death Valley also broke the heat record with a 130-F reading. Live science reported At the time.
Not an extreme stranger, Death Valley is one of the hottest and driest places on earth due to the shape of the valley and its relative position to the mountains. For example, when a storm travels inland from the Pacific Ocean, it trek eastward through the mountains. Steam-dense storm clouds hit the area, rising and cooling, causing condensation and, of course, rain and snow. When the clouds reach the other side of the mountain, the humidity is much less. This is called dry rainshadow. According to the National Park Service (NPS). Clouds tend to dry out by the time they reach the desert, as there are four mountain ranges between Death Valley and the ocean.
These mountains also act as walls around the narrow Death Valley basin below sea level. When sunlight heats the dry surface of the valley, radiation is trapped in these steep “walls,” the NPS said.
But Death Valley isn’t the only one choking under the heat waves. Thermal alerts affect more than 30 million people in the western United States, where triple-digit temperatures are projected throughout the weekend. Reported by CNN..
The National Weather Service has issued “very high” heat warnings in most of California, Nevada, Arizona, and Utah, according to CNN reports. This means that everyone in these areas faces the health risks of heat.
“Repressive heat waves” across the western United States are the result of so-called heat domes, or high-pressure ridges that trap hot air near the surface while preventing precipitation. NWS said in a recommendation..
“110 widespread high temperatures [F] “For the deserts of the southwest and the valleys of central California, the above forecasts are expected,” the NWS said. It’s likely to be in the second half. “
However, there is some sense of security. According to the NWS, the cold front is moving south of Canada and could cool Montana on Monday (July 12). And a pocket of cold air is moving east from the Pacific Ocean, which may provide some relief to parts of Northern California.
