Is it snowing heavily this year?

First, the arrival of light snow solar terms

Now (22nd) has ushered in the annual light snow solar terms. Many people think that after this solar term comes, the weather will get colder and colder, and light snow will come. In fact, the light snow solar terms have nothing to do with whether there is snowfall or not. Light snow is the twentieth of the twenty-four solar terms, and this solar term is also a sign of entering winter. At this time, the cold air activities in the north are becoming more and more frequent, and the weather will only get colder and colder, and the rain and snow weather will also increase.

Light snow is usually165438+1October 22nd or 23rd. This year's light snow solar term is165438+1October 22nd, the eighth day of the 10th lunar month. At this time, the longitude of the sun is 240, and there will be less rainfall, more snowfall and frequent cold waves in many parts of the country. In the eyes of the ancients, "light snow" means snowfall, but there is no snow on the ground. Because the snowfall is small, there is a saying of light snow.

2. Is there much snow this year?

Light snow solar term is a climate concept, which does not directly indicate the snowfall. Meteorology has a clear definition of "light snow". After snowfall, the visible distance is greater than 1000 m, the snow depth is less than 3 cm, and the snowfall within 24 hours is 0. 1-2.4 mm, which is known as light snow.

The first early warning of heavy snow in the second half of 2020 is 17- 19. Northeast China, Inner Mongolia, Hebei and other places will have heavy snowstorms and heavy rains, and it will snow early this winter in many places. While enjoying the snow scene, netizens felt the breath of winter, and felt that this winter was too cold, so they were still comfortable indoors.

According to the forecast of the Meteorological Observatory, this year's La Nina phenomenon has been formed, and the SST in the central equatorial Pacific has dropped abnormally, and its appearance will also lower the temperature. At the same time, La Nina phenomenon will also make the rainfall show a state of "more in the north and less in the south", and it is unlikely that there will be a large range of low-temperature rain and snow in the south.

At present, the National Climate Center has also held a meeting to analyze the climate forecast of 65438+ from February this year to May next year. Let's analyze it.

As can be seen from the above figure, although La Ni? a phenomenon will affect the climate in China, the overall impact scope is not large. In the northeast and east China coastal areas, the temperature is 0.5-2℃ higher than in previous years, so people in these places don't need to worry too much. From June 5438 to February, the temperature will rise slowly, and of course, the temperature in the southwest will also rise.

In the northwest, such as Xi, Hohhot, Urumqi, Yinchuan, Xining, Lanzhou and other places, the temperature is relatively low, 0.5-3℃ lower than in previous years. People in these places should keep warm. In addition, the temperature in South China, Guizhou and other places is also low, which requires special attention.

From the point of precipitation, from 12 to February of the following year, there was more precipitation in the northeast than in previous years, and there was more precipitation in the central region, especially in Xi 'an, Lanzhou, Xining and Yinchuan, and of course there was more precipitation in Xinjiang. The precipitation in South China and Southwest China is 20-80% less than in previous years.

As can be seen from the above figure, from June 5438+February to May of the following year, there is a high probability of low-temperature snowstorms in northwest and northeast China, which means that there is more snowfall in these places than in previous years, and snowstorms may occur in Urumqi, Harbin and other places. Judging from the weather these days, the northeast region is indeed one snowstorm after another, and there is even light snow in North China. It is worth mentioning that there are also low-temperature rain and snow warnings in southwest areas such as Chongqing and Guiyang, which is worth noting. People living around here should take precautions in advance. After all, there were few low temperature and snowfall climates in these places in previous years.

From the above analysis, it can be seen that there will be low temperature rain and snow in the northwest, northeast and southwest this year, and everyone needs to take precautions. East China, North China, Central China and South China are less affected by La Nina, but South China should pay attention to the continuous drought in winter and spring.

Third, is snowfall good for agriculture?

In fact, for farmers, the solar term light snow has many benefits. They hope there will be more snow in winter. There is also a saying in the countryside that "light snow in October will bring a bumper year in the coming year".

After all, after the October of the lunar calendar, wheat has grown seedlings and rapeseed has begun to grow branches. At this time, the old farmers are most afraid of continuing to grow up. Once they grow too vigorously, they should control their prosperity. As for why, it is for the better winter of seedlings.

Snowfall is beneficial to the stability of soil moisture, which can supplement some water to the soil and freeze the pests and diseases in the soil to death. After turning green in the second year, the crops have enough water to grow and will not be affected by diseases, so that the crops grow faster and can usher in a bumper harvest year.

At the same time, there is more snowfall in winter, which means that there will be no late spring cold in the coming spring. I believe farmers are very shocked by this natural disaster, right? However, there is enough light snow in October of the lunar calendar, so there is no need to worry about being affected by the "cold spring" in the coming year.

In addition, in scientific research, it is found that nitrogen in snow is rich, with 7.5 mg of nitrogen in one liter of snow. It is necessary to know that nitrogen is an essential element for crop growth. There is much snowfall, and sufficient nitrogen in the soil can stimulate crop growth.

4. What are the customs of Xiaoxue solar terms?

1, bacon

There are still more than two months before the Spring Festival, and many places have also stepped up the curing of bacon, especially in the southwest. 1 1 is busy in the middle. After the light snow solar term, the temperature plummeted and the climate was dry, which provided favorable conditions for curing bacon. Many farmers will brew bacon and sausages, which are unique and delicious before and after the Spring Festival.

2. eat a gas bar

There is also a light snow festival in the south that pays attention to eating Ciba. Its raw material is glutinous rice, which can be cooked and mashed and then made into food. It is very popular in the south. It used to be a holiday sacrifice, but now it has become an authentic food.

3. Grab agriculture

Before and after the arrival of the light snow solar term, old farmers should pay close attention to rotary tillage, otherwise it will be more difficult to plough again in the future. If you plant cabbage and radish in the farmland, you should also take them home and put them in the kiln, otherwise they will freeze.

After the beginning of the light snow solar term, fruit farmers in the north should also trim branches and wrap them with straw to prevent freezing. If the wheat field is dry, it can also be watered with frozen water in advance to make the wheat winter better.

Of course, there are many customs of the light snow solar term, and different regions have different pay attention to it, but after this solar term, everyone should pay attention to keeping warm and not freezing!
