It is snowing in many scenic spots in Henan. Just after the heavy rain this year, the snow came so early?

People who have studied high school geography should know a phenomenon: La Nina phenomenon. The word originally came from Spanish:? Rani? Answer? The original intention is also beautiful? Saint? . But it's hard to make you feel good after it.

On the specific performance of La Nina: contrary to El Ni? o, it makes the arid place more arid and the humid place more humid; Typhoon increases, and Leng Xia is hot in winter.

The specific reasons are basically known to those who are familiar with high school geography. It is the product of non-traditional atmospheric movement. We won't analyze the specific academic details.

You all know the flood of 1998. That year, not only the Yangtze River was flooded, but also the Songhua River and Heilongjiang in the northeast were flooded. China marine experts and meteorologists believe that this is caused by? El Nino? La Nina phenomenon? Ecological deterioration in the Yangtze River basin.

It was rainy this summer, and we saw the news of long-term floods in Jiangnan.

It's cold overall this year, probably around the beginning of April. I am in the mountainous area of Lvliang, covered with a thick quilt. One night, I was awakened by the cold. It's too cold. The next day, I found that all the newly opened walnut trees were frozen and withered, and the farmers suffered heavy losses.

Just entering September, I have begun to wear long sleeves.

During the National Day, I felt the weather turned cold. I read on the news recently that it snowed in many places. I'm not surprised that the snow in Changbai Mountain is located in the north.

(It's really cold this year)

But I was surprised to see the snowfall in many places in Henan.

According to the general year, the snowfall in Henan is around1February in the solar calendar, and the snowfall thickness is also relatively thin. The National Day snow two months ago, the temperature plummeted and the climate was obviously abnormal.

Friends in the north should all know the solar term of first frost. The first frost means that there will be frost before and after this, which means that crops will stop growing and start autumn harvest.

The first frost this year is 65438+1October 23rd, which is earlier in Shanxi and later in Henan. But compared with snow, the first frost is a pediatrician. If there is no accident, the autumn harvest will naturally begin where it snows.

On October 5th, 65438/KLOC-0, it snowed successively in Laojun Mountain, Baiyun Mountain, Wuwangshan Mountain, Yaoshan Mountain and Laojieshan, which can be said to be winter overnight.

It rained heavily on Laojun Mountain in Luoyang City, Henan Province, and snowflakes floated on the mountainside. For tourists, there is a throb to welcome the first snow. Don't panic when things happen. Why not send a circle of friends with your mobile phone first? .

Except for the lack of clothes preparation, the overall impact is not great.

(It snows in Henan)

Guo Haitao, deputy general manager of Lv Wen Group in Laojunshan, Henan Province, said that due to the high altitude and low temperature in the mountainous areas of western Henan, the first snow in Henan after winter usually falls in the mountainous areas. In the past, the first snow in Laojun Mountain was about 65438+1October 20th every year. It snowed earlier this year, on June 5th, 65438+1October 5th. He analyzed that this is related to the cold air attack in the province.

A careful analysis of the above news will reveal that snowfall is mainly concentrated in mountainous areas. As a whole, it snows early in these mountainous areas. As mentioned above, it snows half a month in advance, so you don't have to be too flustered.

According to the World Meteorological Organization, during September-165438+ 10, the probability of weak La Nina events is 60%. Judging from the current situation, there is La Nina this year, but it should be weak, so don't be too nervous. Remember to take more clothes when you go out, and don't catch a cold. After all, catching a cold during the epidemic is very troublesome.

Just look at the pictures and remember to bring clothes when you go out.
