Why is it rainy in Tomb-Sweeping Day?

When spring comes, the influence of cold air is relatively weakened, and the warm and humid air on the ocean becomes active. Before and after Tomb-Sweeping Day, cold and warm air often meet, resulting in rainy weather, with more low pressure in spring than usual. Low-pressure clouds will pass once, and gloomy rainy weather will appear.

During the Qingming period, rain refers to the climate characteristics of Jiangnan. At this time, it is often cloudy and sunny, and abundant water can generally meet the needs of crop growth. What is annoying and can't be ignored is the harm of wet stains and insufficient light caused by too much rain. Except for the northeast and northwest regions, the daily average temperature in most parts of China has risen above 12℃, and there is a busy scene of spring ploughing everywhere from the north and south of the Yangtze River to the inside and outside of the Great Wall.

Festival custom

However, in the vast area north of the Huanghuai Plain, there is still little precipitation during the Qingming period. Water is often in short supply for crops and spring sowing. At this time, rain is very precious. These areas should be well irrigated in spring to prevent the threat of spring drought while storing water and conserving soil moisture.

Tomb-Sweeping Day, also known as outing festival, outing festival, March festival and ancestor worship festival, is an important traditional festival in China.
