What does the weather forecast mean?

Weather forecast is not a technical term. The windy day is the south wind. As the saying goes, the south wind warms the north wind, and the east wind is wet and the west wind is dry. The term "southerly sky" commonly used by the people is not a specific term in meteorology. But literally, it can be understood that this resurgence phenomenon is related to the warmer south wind, which often occurs every spring or rainy season.
