What plants can forecast the weather?

Mimosa pudica

Mimosa is a common plant in life. In addition to responding to touch, it is also a good predictor of the weather. In the process of closing and opening, the weather has been predicting to people: if you close quickly and open slowly, it indicates that the weather will be good; On the contrary, if it closes slowly and opens quickly, it means that the weather will turn rainy.

garlic

Red flower and green onion, also known as rain flower, can fully prove its position in weather forecast. Two or three days before the storm, the wind and rain flowers can't wait to bloom thousands of small flowers. Therefore, people know that there will be heavy rain in the near future when they see the scene of yuhua district in full bloom. What's even more amazing is that despite the storm, the rain flower is still very lively. The hometown of this magical plant is in Mexico, Cuba and other places, and it is also planted in Xishuangbanna, China.

Verbena plants

Verbena also has its own unique way to predict the weather. It grows in fields and hillsides in Hubei, Jiangsu, Guangxi and other places and belongs to a very common plant. Because verbena is sensitive to humidity, if its exposed roots are moldy and white, it indicates rain.

Gay man

This is a common wild flower variety in Europe. Its leaves are very interesting and can measure the temperature like a thermometer, so it is called "warm grass". Its leaves are extremely sensitive to temperature. When the temperature is above 20℃, the leaves extend obliquely upward. If the temperature drops to 15℃, the blade will move down slowly until it is parallel to the ground. When the temperature drops to 10℃, the blades extend obliquely downward; If the temperature rises, the leaves will return to their original state. People can know the temperature according to the spreading direction of its leaves.

willow

Strictly speaking, it is willow leaves that can truly reflect its weather forecast. If the willow leaves are found to turn white, it may rain. But this scene is not because the willow turned white overnight, but because before the rainy day comes, all the willow leaves will fall, and the reverse side of the willow leaves is light green with a layer of "white frost" on the surface.

Pumpkin vine

Some plants predict the weather by flowering or color changes, while pumpkin vines change their posture. Usually, the top of pumpkin vine grows slowly downward and forward. However, if the top of the pumpkin vine is generally upward in the summer morning, it indicates that the weather will turn from sunny to rainy. On the contrary, if the top of the pumpkin vine is generally downward in rainy weather, it indicates that the weather will be fine.

Although these plants can become "meteorologists", we should not exaggerate their abilities too much. In modern meteorological science, the change of weather is directly caused by the change of atmospheric circulation, which is not only related to the local environment, but also to the circulation conditions in a certain range. The response of plants is often caused by local weather and environmental conditions. Scientists are further studying the problem of plants forecasting the weather. Therefore, when people pay attention to the weather changes, they can't just rely on the changes of local animals and plants to predict the weather. Professional weather forecast depends on satellite, radar and large-scale meteorological data for analysis and judgment, so as to make predictions.
