Zhuge Liang looks at the stars at night

It is not surprising that some weather forecasts can be made through simple meteorological observations. But generally speaking, there are two observation methods, one is to observe clouds and gases, and the other is phenology. Clouds are easy to understand, and the current weather forecast is mainly to analyze cloud images. The so-called phenology, such as swallows flying low, is known as a sign of rain.

Zhuge Liang in the Three Kingdoms was deified. Predicting the weather, "watching the stars at night" is tantamount to nonsense. It is better to watch the clouds during the day and listen to the wind at night.
