Atmospheric river to Wallop California because the study worsens storms | California

A strong atmospheric storm in California was set in California on Wednesday evening. He brought large parts of the state with rain and brought several foot to the mountains – the latest in a wave of intensive storms that show new research results.

A large part of Northern California was in the forecast because of the gusty winds and the strong snow that the National Weather Service (NWS) said that the National Weather Service (NWS) would lead to “difficult to impossible travel conditions”. According to reports, heavy thunderstorms and strong winds were predicted in the San Francisco Bay Area.

The NWS have published a flood guard in large parts of South California by Thursday afternoon. The region also expected dangerous driving conditions as well as flood and debris flows in areas affected by the latest forest fires. Los Angeles put several areas under evacuation warnings and orders due to the risk of rain in rain and announced the closure of several streets, including part of the Pacific Coast Highway.

In the meantime, the state office for emergency services announced that more than 400 employees, including rescue teams of Swift water and urban search and rescue staff, sent across the state to prepare for the storm. The authorities advised the residents to have a go-bag ready and prepare for power failures.

Atmospheric rivers, long and relatively narrow water vapor ribbons that take moisture out of the ocean and design massive rainy amounts play a crucial role in the filling of the reservoirs and the state’s snow cover. However, they were also behind some of the most devastating storms in California, including the extreme weather, in which around 20 people were killed in 2023, and increases with frequency and severity.

A comprehensive examination of the atmospheric rivers in the current edition of the Journal of Climate showed that the strong rain and wind events that are best known, California and other parts of the West have become greater, humid and more frequent in the past 45 years.

Atmospheric rivers have increased 2% to 6% in the area in which they soak by 6% to 9% and are slightly humid than before, according to the study.

Scientists have long predicted that the climate crisis caused by burning coal, oil and gas keep air warmer more moisture, which means larger, poor atmospheric rivers in the future. The new research results show that a moist future is already here.

“This does not mean that it is necessarily everything because of climate change. We have not examined this, but on the whole it is shown with some expectations of how (atmospheric rivers) will change in a warming atmosphere, ”said the main author of the study, Lexi Henny, an atmospheric scientist at the University of North Carolina, who conducted her research on NASA.

What has already happened “in relation to the changes that we believe in a future warmer world,” said Henny.

While atmospheric rivers urgently needed rain can bring to drought, they are often dangerous. Last year, a number of atmospheric river storms caused hundreds of mudsmiths and killed several people in California. In the 1860s, California had to lay its capital from Sacramento because the floods caused by atmospheric river.

These events occur throughout the USA and in the world, although sometimes not caused by atmospheric rivers, said Henny. An atmospheric river storm in New England in 2023 brought a foot rain and 50 km / h wind. A 2020 Atmospheric River left 99 inch snow on Alaska.
