What is the relationship between cicada chirping and sunny weather?

Cicada, commonly known as "cicada", likes dry and hot weather and mostly inhabits tree trunks and branches. Whenever the weather is sunny and hot in summer, especially in the afternoon and evening, they often flutter their leaf wings and shout "Cicada, cicada...", adding a unique style to the entire green nature. tune. However, when the weather turns cloudy and rainy, the cicada's leaf wings become wet due to a sudden increase in water vapor content in the air, making it difficult for them to move, and of course they cannot make a cry. So when the weather is hot and muggy, if the sound of cicadas suddenly stops, it means that wind and rain will soon come. When it turns sunny after the rain, as the air humidity gradually decreases, the wet leaf wings gradually dry out and recover, and can start to scream "cicada" again, so there is a folk saying of "hearing cicadas chirping in the rain" , a saying that predicts the weather will be sunny.

The chirping of cicadas can not only predict whether it will be sunny or rainy, but also predict whether the rainy season in early summer will end. In the late plum rain period, if you hear the chirping of cicadas, it indicates that the plum rain will end, the weather will become sunny, and the hot midsummer will begin.

When we use this folk proverb, we must pay attention to distinguishing the characteristics of the beginning and end of the cicada sound. Don’t mistake the cicadas that stop chirping after dark to mean that it’s going to rain.
