Why is there a phenomenon of "cold spring" this year?

The winter in our country is very strange this year. According to common sense, the north of our country should be the place with the most snow. However, Heilongjiang Province, the northernmost province in China, hardly snows. It has snowed several times in the south of China this winter. Such abnormal weather makes farmers feel very worried. Farmers live on the land, and the harvest of crops on the land depends on the weather. If the weather is good, then the harvest will be good, if the weather is bad, then farmers will not make money.

First, what is a cold spring?

In early spring (especially at the end of February). In early March, the temperature recovered quickly, but in late spring (April to May), the temperature was lower than normal. In other words, the temperature changes from high to low at this time, which can cause large-scale freezing damage to crops that turn green or sow in spring, and is a major climate disaster in agricultural production. Our ancients were very clever. They recognized the change of weather very early, and divided the four seasons into four seasons according to the law of meteorological change, which is what we all know as spring, summer, autumn and winter. So this? Cold spring? In fact, it is a sign that the weather does not follow the routine: after spring, it is reasonable to say that summer will follow, and the temperature will get higher and higher. However, due to the sudden change of temperature, the originally higher and higher temperature suddenly becomes cold, which is called late spring cold.

Second, will there be a late spring chill in 20 19?

China is a typical country with monsoon climate. March-April is the time when the wind direction in winter changes to the summer monsoon, so it is often attacked by cold air, and it is easy to have late spring cold. Therefore, for the late spring cold, the probability of occurrence in China is very large. However, according to the analysis of the El Ni? o phenomenon, experts believe that the El Ni? o phenomenon will last until around April. After that, the climate will be mainly warm, so there will be a high probability of cold weather after April next year.

Therefore, it is unlikely that there will be a large-scale cold spring next year, but it is better for farmers to take precautions. After all, the climate change in recent years is very unstable, and there are not enough laws to explore. The forecast is for reference only, or I hope everyone can take precautions in advance, pay more attention to the weather forecast and avoid losses!
