What are the signs of snow in Grain Rain?

Snow in Grain Rain is usually regarded as an unusual climate phenomenon, which may indicate climate change or some natural disaster. The omen of snow in Grain Rain can be interpreted as: 1. Sudden drop in temperature: Grain Rain is a solar term in spring, marking the official start of spring. If it suddenly snows at this time, it usually means a sudden drop in temperature, which may have a negative impact on crops and agriculture. 2. Abnormal weather: Grain Rain is the previous solar term of rain. In rainy season, the weather gets warmer and the rainfall increases. The appearance of snow means abnormal weather, which may be accompanied by strong cold air, cooling and meteorological changes. 3. Climate prediction: Snow in Grain Rain may be a precursor of climate change, implying the extension of winter or the postponement of spring. It may reflect environmental changes, disturbances of global climate patterns or abnormal weather phenomena.
