Is there a relationship between severe drought and severe floods?

Unscientific.

“There is no inevitable connection between severe droughts and severe floods, and there is no causal relationship.” Experts believe that the atmospheric circulation that causes drought or flood disasters is different, and the changes in atmospheric circulation have certain rules, and different It will definitely go from one extreme to another, but extreme changes are also possible.

There are no sufficient facts to prove the statement that "a severe drought must be followed by a severe flood". It may be that one year such features were so obvious that they left a deep impression on people and spread word of mouth. Extended information

For example, meteorological experts said that in 1997, the province's drought-affected area was 981,300 hectares, and the flood-affected area was 579,300 hectares in the same year. Both drought and flood disasters in this year were serious.

However, the drought area in the province reached 2 million hectares in 2005, which was much more severe than in 1997, but the flood area was only 25.12 hectares. These two sets of data are enough to show that there is no inevitable connection between severe droughts and severe floods.

The meteorological department cannot therefore predict whether Yunnan, which has experienced a severe drought, will experience excessive rainfall in this rainy season.
