Which direction does it rain?

It can be said from summer. Wind is the easiest phenomenon to detect in summer, and we can identify weather changes from different wind directions. It is said that "one east wind brings three days of rain, and three days of east wind brings nothing." Cyclones always move from west to east. In summer, it is very effective to predict the weather changes in the next few days based on the east wind. If the east wind blows for only one day, or changes direction in less than one day, it is a sign of rain, and this rain is likely to last for three days at a time. On the contrary, if the east wind blows continuously for three days without stopping, it will not rain. The southeast wind comes from the ocean. In summer, because the warm air flow is stronger than the cold air flow, when the southeast wind blows, the frontal cloud and rain belts are pushed to the north. At this time, the middle and lower reaches of the Yangtze River are controlled by a single warm air flow, and the air lacks the conditions for upward movement, so water vapor naturally cannot rise into clouds and rain. "Northeast wind brings rain", it is a sign of rain in summer. This is because it is a cold air flow that contacts the warmer ocean or land surface when it goes south, causing convection phenomena of coldness at the top and warmness at the bottom. This creates the conditions for cloud formation and rain. In addition, "the wind is the head of the rain, and the rain will stop when the wind is strong" means that before a shower, the wind is often the first, and the wind blows first, and then the rain falls. When the rain stops, the wind increases first, and then the rain stops again, that is, "the strong wind covers the fierce rain." Therefore, if you learn to read the wind in summer, you can roughly predict the direction of rain.

Regarding the relationship between rain and wind direction: The east wind rains, the west wind clears and rains for a long time, the west wind clears, the west wind rains for a long time, the south wind is warm, the north wind is cold, the east wind is moist, the west wind is dry, the long rain and the cold wind sweep, the sky is clear and reliable, the north wind blows in July, the rain is timely, the spring blows, the east wind rains. Boom, the east wind blows in winter and the rain leaves no trace, the east wind blows in autumn and the rain is drenched, and the east wind blows in summer and the rain is drenching. If there is rain, the sky will be bright, and there will be light on the top if there is no rain
