'California's hurricane is one of the biggest storms in history

The Director of Emergency Services at the California Governor's Office said the storm was one of the biggest storms in the state's history. This California flood reminded people of the flood of 1861. Even then, during Christmas itself, floods started wreaking havoc. According to the report of Michael D. Dettinger, a researcher of the US Geological Survey, the flood of 1861 continued for 43 days. At that time also such conditions were created in California due to the atmospheric river.

After all, how and why Atmospheric River is formed?

Atmospheric rivers are generally formed in tropical regions. Due to the hot temperature there, sea water turns into steam and accumulates in the atmosphere. Strong winds drive the water vapor toward the upper surface of the atmosphere. During this, water vapor moves from one place to another on the surface of the earth like a river with strong winds.

'Pineapple Express' is the name of the world's largest and most dangerous atmospheric river. Its maximum effect is seen in the western part of America and Canada. Because of this 'Pineapple Express', it is raining up to 5 inches in a day at many places in California.

California's drought will not end even with dangerous floods

While California is in the grip of floods. At the same time, according to an estimate, even this flood will not be able to reduce the drought there. According to the Washington Post report, due to the heat wave that has been going on in California for the last three years, there has been so much drought that this flood will have little effect on it. Daniel McEvoy, a researcher at the Desert Research Institute of Nevada, said in California Compared to the excessive rains, the intensity of heat is increasing there in the summer season.
