As the saying goes: When clouds go east, everything is empty; when clouds go west, the Yellow River overflows. Is there any scientific basis for this? !

As the saying goes: "Clouds are the signature of the weather." The shape, height, and movement of clouds directly reflect the state of weather movement at that time and indicate future weather changes. Folks attach great importance to reading clouds and measuring the sky. There is a proverb about the weather: "When clouds go to the east, everything is empty; when clouds go to the west, the water is miserable; when clouds go to the south, the rain becomes a pool; when clouds go to the north, it is good to dry the valley." Clouds move east and southeast, indicating that west to northwest winds are blowing high in the sky, so there is "clouds moving east, nothing." "Clouds to the west" refers to the turn of summer and autumn, when clouds extend from the east or southeast, which is often a sign of typhoons, so the water will be "bleak". Clouds moving southward means that cold air moves southward, and cold and warm air masses converge to cause rain, so "clouds move southward and rain forms a pool." The clouds move northward, indicating that the area is controlled by a single warm air mass, and the weather is rainless, making it "good for the sun". The clouds are consistent up and down in the sky, and the weather is relatively sunny. The high and low stratus clouds move in inconsistent directions, and the weather changes will be intense and complex. As the proverbs say, "There are clouds in the sky, and rain is pouring on the ground."
