People often hear cicadas cry, sometimes high and sometimes low. What's the impact on the weather?

Cicada, commonly known as cicada. In early summer, people often hear cicadas, sometimes high and sometimes low; Sometimes it keeps chirping, and sometimes it is silent. Careful observation shows that cicada singing is also related to weather changes. In He Lixia, northern Jiangsu, people have a lot of experience in predicting the weather with cicada singing, such as "cicada singing disappears when the rain disappears", "plow with the sun before cicada singing", "cicada singing after three swallows, southwest wind and fine weather".

In Xinghua area, cicadas are also used to predict the end of Meiyu and the water level of the river: in rainy season, within two to three days after cicadas start, Meiyu will come to an end, and the water level of the river will no longer rise sharply and tend to be stable. The prediction accuracy is also very high.

Through nearly eight years of observation, the majority of rural meteorologists found that the relationship between cicada singing and weather changes is:? "When you know the sound, it will become clear." In summer, after a thunderstorm, cicadas will scream, indicating that it will be sunny in the future. ? "The cicada is singing, and the weather is fine."

On a hot summer night, the stars have appeared in the sky. At this time, the cicada is still chirping instead of "resting", which indicates that the weather will be fine and hotter the next day. ? "The cicada's cry has stopped, and even the rain will come." In the summer solar term, the weather is getting hotter and hotter. At this time, if the cicada stops, that is to say, sometimes the cicada calls "cicada, cicada stops" everywhere, and sometimes it can't be heard at all for a day or two. In this case, the crowd called cicada to stop, which indicates that it will rain in the next three to four days. ? In the sunny and hot summer, cicadas make noises in the trees, and when they see them climbing up or down, they cry while climbing, which indicates that there will be thunderstorms in the future.

Observing the end of cicada chirping in the morning and evening can also predict the speed of cooling in the later period. Generally speaking, from the beginning of autumn to the summer solar term, cicada singing will end with the cold weather. If the cicada song ends early (that is, the day before the beginning of autumn solar term), it indicates that autumn will turn cold and the first frost will come early. This is what the masses say: "cicadas end early, and autumn turns cold early."
