What are the consequences of the rare snowstorm and gale in Dalian?

It is said that in winter, the next snow is good for the climate and farmland. However, it is not a good thing to keep snowing endlessly. Snow after the year is beneficial and harmless to crops, and snow or rain in spring is very precious. Farmers have the saying that spring rain is as expensive as oil. In spring, crops begin to grow, and the demand for water gradually increases. Years later, snow or rain can provide enough water for crops, make the leaves of crops generous and powerful, and reduce pests and diseases.

Rain and snow are very important for winter wheat and rape after the year. If it rains and snows in spring, farmers will surely have a bumper harvest. Spring is also the season of sowing, crops emerge well, and it is also the first rehearsal of harvest. Therefore, the rain and snow after the year is the favorite rain and snow of farmers, and it is also the rain and snow of farmers' harvest. Only when the crops are harvested can farmers' pockets swell up.

As the saying goes, "Snow bodes well", whether it snows the year before or the year after, it is a good omen. Snow is the quilt of wheat seedlings, which can prevent wheat from freezing injury and increase soil moisture. The old man said that snow in winter and Chun Xue can kill underground pests. Therefore, snow is harmless to crops. The more rain and snow in winter, the better, which means that the year is good and "the grain is abundant". Rain and snow are acidic, which can freeze soil, loosen soil, prevent soil from hardening and have good air permeability. Weathered wheat fields and winter ploughing have laid good conditions for spring sowing. In addition to the great impact on traffic and greenhouses, it is very beneficial to crops and trees.

In fact, the heavy snow is brought by the cold wave. This cold wave not only brought heavy snow, but also brought strong winds to cool down, which made Dalian have a rare extremely low temperature, which is also rare in winter in Dalian. As the saying goes: too much is too late. Snow in winter is actually equivalent to meteorological rainfall. However, excessive snowfall is definitely not a good thing, at least it has a very negative impact on urban traffic. During this period, Dalian was in the epidemic prevention period, and as a result, it snowed again, which was really a test for this city. It is necessary to prevent epidemic and remove snow, and sometimes it really seems to be stretched.

It used to be a good thing to snow, which could freeze some viruses to death. However, it is not a good thing to snow now, especially in COVID-19, which is not afraid of heat and cold, but it is not good for epidemic prevention. So Dalian is not afraid of snow. After all, winter in Dalian is very dry. It would be nice to have some snow. But it snows so frequently and so heavily recently, which is definitely not a good thing for Dalian. After all, it is "too much".
