Weather proverbs and simple explanations There are simple explanations about weather proverbs.

1, "Hook clouds are hanging in the sky and raining underground": Hook clouds are called hook clouds in meteorology, and generally appear in front of warm fronts and low pressure, indicating that front or low pressure is coming, which is a harbinger of rain. But after rain or winter, there will be sunny days or frost one after another; Proverbs such as "the hook cloud dissipates, the sunny day is dry" and "the winter hook cloud dries up".

2. "The clouds are heading east, blowing gusts; Clouds go west, covered with hemp fiber ":The cloud here refers to the low cloud in the low-pressure area. The low pressure is from west to east (in fact, it often moves from southwest to northeast). The cloud goes west, indicating that this place is in front of the low pressure, because it will rain locally; The cloud is moving eastward, indicating that the low pressure has moved past the local area, and the local area is behind the low pressure. The weather is going to clear up, and a strong wind often blows before it clears up.

3. "Dark clouds cover the sun in the morning, and there is no wind to rain": it means that there are dark clouds covering the sun in the southeast in the morning, indicating rain. Because the warm and humid southeast wind blows in the morning, the temperature is higher than the local air, which causes the upper part to be cold and the lower part to be hot, and the water vapor easily rises into clouds. In addition, during the day, the ground is heated, and the air convection rises, which further promotes the clouds to rise. When it meets cold water vapor, it becomes water droplets, which may make it windless and rainy.

4. "Wearing a hat on a mountain makes it rain heavily": Wearing a hat on a mountain means that the air pressure is low, and most of the water vapor in the air forms clouds at the top of the mountain. As for whether it will rain, it generally depends. If the clouds gradually decrease and thicken, there is a great possibility of rain. On the contrary, if the clouds gradually rise and thin, the possibility of rain is small.

5. "Early rain is sunny, but late rain is difficult": Early rain indicates that it will be sunny these days; It rained very late, which shows that it is difficult to clear up these days.
