Why does it always rain around Qingming Festival
1. Every year, the Qingming Festival is around April 5. It's the time when winter goes to spring. The power of cold air is not so strong, and gradually weakened. At this time, the subtropical high begins to strengthen its westward extension, and the warm and humid air on the ocean begins to be active in the North. It's eager to try. The cold and warm air often meet in the south, making the South rainy and rainy weather even. It is worth mentioning that this year's Qingming rain in the south is largely due to the cold air going south.
2. In the spring of Jiangnan, there is a lot of low pressure. The clouds in the low pressure go very fast, the wind is very strong, and the rain is very urgent. Every time the low air pressure passes by once, there will be gloomy and rainy weather.
3. Before and after the Qingming Festival, the warm and humid air flow from the ocean constantly transports to the mainland. There is more water vapor in the atmosphere, which is easy to condense into drizzle in the evening. Because of these reasons, there are many rainy days in Qingming.
