Why is it always raining in Suzhou these days? What is the reason?

This is a normal climate phenomenon, because February 19 is "rain" according to the lunar solar terms, which not only indicates the beginning of rainfall, but also indicates that rainfall begins to increase, and rainfall is the season when cold waves appear more. At this time, the warm and humid air flow from the ocean is gradually advancing northward, while the cold air is not to be outdone, and frequently competes with the warm air, but the general trend is the transition from the cold in late winter to the warm in early spring. In ancient China, rainwater was divided into three stages: "First, Tyrannosaurus Rex sacrificed fish, then geese came, and plants sprouted." It shows that otters start fishing in the rainy season; Five days later, the geese began to fly back to the north from the south; In five days, the vegetation will quietly spit out buds in the continuous spring rain.
