Whenever a storm comes, many beautiful flowers will bloom. Are there such magical flowers?

There is a wonderful flower in Xishuangbanna, Yunnan Province. Whenever a storm comes, there will be a lot of beautiful flowers in full bloom. The red petals dyed the whole mountain forest and the cliff red. According to this feature, people can know the weather changes in advance, so it is called rain flower. ?

There is a magical flower that grows in Australia and New Zealand. It can also predict the weather. Everyone calls it yuhua district. This kind of flower is very similar to the chrysanthemum in China. Petals are also very long and have different colors. The difference is that it is two to three times larger than chrysanthemums.

So, why can newspapers make yuhua district forecast the weather?

This is because the petals of primrose are sensitive to humidity. On the eve of rain, the air humidity increased. When the air humidity increases to a certain extent, the petals will shrink and tightly wrap the stamens, which indicates that it will rain soon. ?

When the humidity in the air decreases, the petals will slowly spread out, which indicates that sunny days are coming. ?

Local residents always take a look at the Yuhua newspaper to understand the weather before going out, so people affectionately call it the "weatherman". There is an elm tree next to Dateng Village, Gaoguan Township, Anhui Province, China. 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. ?

There is a green bar tree in Dinglong Village, Xincheng County, Guangxi Zhuang Autonomous Region, China, with the age of 100. The color of its leaves changes with the weather. On sunny days, the leaves are dark green. After a long drought, the leaves turn red; When the weather cleared up after the rain, the leaves returned to their original dark green. So people call it "weather tree". ?

This kind of Qinggang Tree is very sensitive to climate change in the process of adapting to the living environment for a long time. Before the long drought is about to rain, there will often be sultry and sunny weather. At this time, the synthesis of chlorophyll in leaves was inhibited, while the synthesis of anthocyanin accelerated and occupied the advantage of leaves, so leaves turned from green to red. ?

After the rain cleared, the synthesis of anthocyanins was inhibited, which accelerated the synthesis of chlorophyll and made chlorophyll cheaper, so the leaves returned to the original dark green. ?

Small knowledge and big vision?

Crops can also predict sunny and rainy days. In the summer morning, if the vine head of the pumpkin leans downward, it indicates that it will rain. In rainy weather, if most of the vines of pumpkin are tilted upward, it indicates that sunny days are coming, because pumpkin vines have the instinct of turning sunny to cloudy.
