What kind of trees can forecast the weather?

There is an elm tree next to Dateng Village, Gaoguan Township, Hexian County, Anhui Province. Surprisingly, this is a "meteorological tree" that can predict the drought and flood in that year.

People can infer the rainfall of that year according to the time when trees germinate and the density of leaves.

If this tree sprouts in front of Grain Rain and grows luxuriantly, it indicates that there will be more rain, high water level and frequent floods. If it, like other trees, germinates with the seasons and leaves grow densely, it will be a good year with good weather; If the germination is delayed and the leaves grow less, it means that there was less rain and serious drought in that year.

Decades of observation data prove that it is quite accurate to predict the drought and flood in that year.

After a preliminary investigation, scientists believe that this may be because this tree is particularly sensitive to the ecological environment and has played such a strange role.
