Bomb cyclone hits US, causing air pressure collapse and heavy snow

Arab Weather - The latest updates issued by the Arab Weather Center, based on approved computer models, indicate an increase in polar storm activity in North America. Several states in western America, including Washington and Northern California, are witnessing severe weather fluctuations, as a result of a huge polar air mass rushing towards the Pacific Ocean, which caused the formation of a polar storm with very low atmospheric pressure values.

Experts at the Arab Weather Regional Center explained that the weather systems in the northern hemisphere are heading towards a form closer to winter. The influence of polar air masses over the Arctic Circle has increased, which has led to the rush of very cold air from the North Pole towards North America. As a result of the polar winds crossing the waters of the Pacific Ocean and the interaction between the cold air and the warm and humid weather systems in the ocean, a deep air depression has formed, which has developed into a strong storm with low air pressure values reaching 940 millibars, which is centered off the coast of Washington, causing severe weather disturbances.

The storm is accompanied by a massive cold front that will bring strong winds and high waves, with heavy rain and snowfall in many areas, including northern California, Oregon and Washington. Temperatures are expected to drop below zero in several areas, where the weather is very cold.

Strong winds caused power outages. As of Wednesday morning, more than 600,000 homes in Washington state were without power, according to poweroutage.us. About 15,000 customers were experiencing power outages in California.

The collapse in air pressure at the center of the storm highlights the occurrence of the fragmented annular explosion phenomenon.

With the collapse of atmospheric pressure at the center of the storm, experts at the Arab Weather Center said that the phenomenon of "explosive cyclogenesis" or bomb cyclone was prominent in the storm, which is a weather phenomenon that results in a collapse in atmospheric pressure values to reach values similar to the atmospheric pressure values in tropical storms and hurricanes, but outside the tropical region. The storms that arise from this phenomenon do not acquire any tropical characteristics.

A bomb cyclone occurs when a cold air mass meets a warm, moist one, causing a drop in air pressure of 24 millibars in 24 hours. This type of weather phenomenon is most common in the North Atlantic Ocean.

And God knows best.
