What are the characteristics of nature?

Spring east wind, rain ancestors; In spring, the east wind and the rain murmur. These two proverbs mean that the east wind blows in spring, which is a precursor to bad weather. This is because, on the one hand, the ground will get warmer in spring. On the other hand, the warm air is gradually active, the continental pressure is gradually decreasing, and the anticyclone moves eastward into the sea. An easterly wind will appear at the tail of the anticyclone. These easterly winds flow to warmer land, leading to the phenomenon that the upper part is warm and the lower part is cold. At this time, the air layer is unstable and prone to upward convection, so it is very likely to produce precipitation.

2. Thunder and rain

There are castle clouds in the sky and thunderstorms on the ground. Castle cloud indicates that it will rain tomorrow, which is a clear weather forecast method. The weather brought by this cirrus cloud is clear and cloudless, so everyone can go out safely. In summer, the cauliflower shape of cumulus shows that water rises rapidly and cools, while dry air continues to stay at high altitude.

3.swallow

Swallows are flying low in the snake aisle, and heavy rain is coming. Before it rains heavily in summer, the air pressure will generally decrease, but small animals such as swallows and snakes are very sensitive to the air pressure decrease and will fly around, which means it will rain heavily.

4. Morning glow and sunset glow

Stay indoors at sunrise and travel thousands of miles at sunset. Don't go out on cloudy days in the morning, because the weather may be bad; When it is cloudy at night, the weather will be fine the next day and you can travel.

5. Spring thunder

Spring thunder, everything grows. Spring thunder has come, spring has come, everything has revived, and the new year has arrived. This proverb is about the solar terms that scare people. Scared sting, called "Qixi" in ancient times, is the third of the 24 solar terms in the lunar calendar, marking the beginning of the mid-spring season. In the past, animals hid in the soil in winter without drinking or eating, which was called "sting"; Speaking of "quiet people", the spring thunder in the sky woke up the secluded animals, which is called "quiet".
