What do you mean by cold spring? What is the omen of late spring chill?

Introduction: Although it is already March in spring, it has just warmed up for a few days, and the temperature has started to drop sharply again. This is the so-called cold spring. What does this mean? What are the signs of late spring cold? Let's have a look!

What do you mean by cold spring? Late spring cold refers to the spring, when the climate begins to get warmer, but the cold air raids, resulting in continuous low-temperature weather, which is as cold as winter. The biggest harm of late spring cold is that it is more harmful to crops.

In fact, this phenomenon is also caused by many weather reasons, that is, the weather is getting warmer after the New Year, but there will be some obstacles in this process, such as the invasion of cold air. Once this phenomenon happens, it may make the local temperature drop gradually, making people feel the obvious temperature difference. In the Spring Festival, I am most afraid of this phenomenon. It was originally a very happy day, but it is inevitable that people will feel uncomfortable to dress very bloated.

In addition, it may also affect crops. You know, in rural areas, people are very concerned about the growth and yield of crops, and the growth and yield of crops are also closely related to the weather, so people pay special attention to the changes of the weather. This kind of weather may have a great impact on crops, and at this time, crops are generally in a relatively immature state, which is likely to cause crop seedlings to die or even grow slowly, eventually leading to crop yield reduction. Therefore, farmers don't want such weather at all, and they don't want to face the losses caused by the weather to crops.

Another explanation in other rural areas is to simplify this sentence. In other words, when spring comes, the temperature will rise significantly, and the comfort of the human body will be particularly good. However, when spring comes, the temperature will probably drop sharply and the human body will feel very cold. So this temperature span is relatively large. Originally in people's consciousness, it should be cold in early spring, and it will be warmer later. however

What are the signs of late spring cold? When the temperature gradually warms up and then suddenly drops, it is cold in spring.

Spring cold refers to the early spring, which often means that the temperature rises rapidly in early March, but in the middle and late spring, that is, in April and May, the temperature drops again. The folk saying is "warm before spring, cold after spring", and this kind of weather is called cold after spring. It often occurs from the beginning of March to the end of April, with a time span of two months, generally earlier in the south than in the north.

Because what we call "late spring cold" refers to the sudden drop after the sudden rise of spring temperature. If it is such late spring cold, then the answer is: there must be; If it is a cold spring in agriculture, that is, the temperature rises rapidly in early spring (generally refers to the end of February and the beginning of March) and the temperature in late spring (generally refers to April) is lower than normal years, then the answer is: no.

Late spring cold is also a weather phenomenon that has great influence on agriculture. Because spring is coming, if the cold air cools frequently, the temperature will continue to be low, which is very unfavorable to the growth of crops. Crops are easy to freeze, unearthed crops may rot, and unearthed seedlings may freeze to death.

In spring, the sun is warm during the day, and the temperature changes very cold in the morning and evening. Frequent cold air activities lead to a large temperature difference between day and night, which makes people feel uncomfortable. This is called cold spring. The cold in late spring affects the growth of crops, and some plants have just begun to sprout, which requires a warm and stable climate. The late spring cold directly leads to the slow growth of crops, and even directly freezes to death, which affects the yield.

If you feel cold, it may be the great cooling in these two days. Because of the intense heat in the south of the Yangtze River over the weekend, the temperature in Shaoxing and Hangzhou was over 30 degrees, which was not the proper temperature in this season, but was blown to pieces by man-made high temperature, so a cold air crossed the border and returned to its original shape, dropping to 10 degrees, and the summer clothes were changed into winter clothes.
