Overflowing weather

As the saying goes, "clouds are a sign of the weather". The shape, height and direction of clouds directly reflect the state of weather movement at that time and indicate the future weather changes. People attach great importance to watching clouds and measuring the sky. There is a weather proverb: "Clouds go east, empty, clouds go west, and water is sad;" Clouds go south, rain pools, and clouds go north, which is good for sunning the valley. "The cloud moves to the east and southeast, which means that the wind blows from west to northwest at high altitude, so there is a saying that" the cloud moves to the east and is empty. " "Clouds are heading west" means that at the turn of summer and autumn, clouds extend from the east or southeast, which is often a sign of typhoon attack, so they will be "sad". Yunnan moves, which means that cold air moves south, and cold and warm air masses meet and cause rain, so "Yunnan moves, and rain becomes a pool." "The cloud moves to the north, indicating that the area is controlled by a single heating mass, and there is no rainfall, which is' good drying'. The clouds in the sky are consistent and the weather is fine. The upper and lower clouds move in different directions, and the weather changes will be more intense and complicated. As the saying goes, "clouds meet in the sky, and it rains cats and dogs underground", "sailing with the wind, against the prevailing rain" and "clouds will change against the trend"
