This winter will form the Rena incident "cold winter" really coming?
Original title: This winter will form the Rena incident "cold winter" really coming? Netizen said: The down jacket has been washed, quietly plus the electric blanket □ Top News · Dahe Daily reporter Kang Yafei Recently, the National Climate Center official announced an important news: since July this year, the East Pacific, the East Pacific has continued to decline since July this year. It is expected to enter the Lenna state in October and form a weak to medium intensity of Ranina events in winter.
What does the happening of Ranina events? What changes will this be winter temperature this year? The Ranina event will form my country’s winter temperature precipitation will be affected from this year’s domestic local area extreme cold wave, and in February, the high temperature is warm. In May, the tornado is extremely strong in July, and the continuous heavy rain rain in July, and the temperature of the air temperature in October. It has been found that this year has undergone multiple extreme weather, extreme weather events are developing into new normal.
At the National Climate Center, the official will form a weak to the medium-strength Ranna incident this winter, this winter will not be a cold winter problem, will this winter will be abnormal? Before we came first, let’s take a look at the Lanina event. The publication shows that "Lanna" event refers to the extraordinary cold water in the East Pacific ocean temperature, and the intensity and duration reaches a certain condition.
In general, Lanina phenomenon has appeared after the El Ni?o phenomenon, so it is also known as an anti-El Ni?o, and the two are considered to be an important cause of global abnormal climate.
In general, the frequency of extreme cold events in the northern hemisphere is increased in winter. For my country’s climate, the influence of "Ranina" can be seen from the two aspects of temperature and precipitation. Most of the "Lanna" incidents reach the period in winter. At that time, my country’s cold air activities are more frequent and intensity than all years. Strong, the temperature of most of my country’s central and eastern part is larger than the probability of low in the same period of the year, and the water vapor conditions in the southern part of our country will be significantly deviated from the same period of the year, which is not conducive to forming precipitation. Ranna came to cold winter without necessity, Ranina is not a "cold winter" absolute signal. According to the climate statistics, when the "Lanna" event occurs, my country’s winter polarization is large. The meteorological department passed the results of 15 "Lanina" incidents in my country since 1951: 10 La Nina’s winter temperation is low, and 5 Lianina is high in winter temperatures. That is, from the scientific point of view, it is not a low average temperature in the winter of Ranina, but after the Lena incident, the probability of cold in my country is twice the probability of cold.
It is worth mentioning that "cold" "shifting" is compared to the average, but the determination of "cold winter" "warm winter" is strictly standard.
According to the data released by the National Climate Center, when the average temperature of the single station is less than or equal to the standard deviation – times, the number of cold winter stations exceeds the total number of 50%, the cold winter area exceeds 50% of the national effective area, is cold winter .
Last winter, in 2020 from December 12 to 15th, from January 5 to 8th, from January 5 to 821, my country has experienced four big cold trends. I have an impressive small partner, I should remember that many areas can be said to be cold to break record, so seeing last year’s winter, it is no problem, but in March this year, National Climate Center released news, 2020 From December 1st to February 28, 2021, the winter is warm.
Cold winter is a climate concept, not absolutely represents our actual sense, so after the Finaana incident, we still have to prepare in advance to respond. After the sunny day, Henan temperature will drop 4 ° C to 6 ° C, the province, which is more than 6 ° C, and the winens in the southwest of Nanyang area. There are small rain or sporadic rainfall; other areas cloudy clouds. The province is biased from 2 to 3, the lowest temperature western mountainous region 7 ° C to 9 ° C, other regions 9 ° C to 11 ° C; the highest temperature western 17 ° C to 19 ° C, other regions 20 ° C to 22 ° C.
Today’s night to 30 days, the province is cloudy in sunny day.
On the 31st, the western cloud is cloudy, and there are small rain or sporadic rain; other areas are cloudy.
The provincial capital Zhengzhou has a cloudy day, sunny day.
Participate in the South Wind 2 to Level 3.
Minimum temperature: 10 ° C to 11 ° C; maximum temperature: 21 ° C to 22 ° C. On the 29th night to the 30th day: sunny day, 11 ° C to 24 ° C; 30 days to 31 days: cloudy, 11 ° C to 20 ° C.
