Recently, news about "warm winter" or "cold winter" has attracted wide attention from all walks of life. According to the analysis of domestic and international meteorological agencies and relevant parties, this year's La Niña phenomenon is brewing. La Niña does not mean that La Niña has entered a cold winter, but based on past observations, it is still quite useful on a global scale.
Historically, we're more likely to have colder winters in a year where La Niña occurs. According to weather data, there have been fifteen La Niñas from 1951 to the present, and five of the ten winters on the continent have seen warmer events.
This shows that in the next few months, there is a high probability of a "cold winter" in China.
Until today, the impact of La Niña has finally ushered in a new development! The potential consequences of La Niña this winter have been reacted to.
According to officials from the Ministry of Agriculture, according to the weather forecast, the mainland is now in La Niña weather. A weakening to moderate La Niña is expected in December. Recently, the Ministry of Agriculture and the China Meteorological Administration jointly released an analysis of the impact of "La Niña" weather on the output of agricultural products in the mainland, predicting that the temperature this winter will be generally "hot first and then cool", and there is an obvious "hot and cold alternation" between "cold" and "cold". From November to December, there will be a phased drop in temperature.
According to the forecast of the meteorological observatory, in January and February next year, the cold air will cool down significantly, and there will be a certain period of cold waves. However, according to the analysis of the relevant authorities, the probability of large-scale snowfall and frost like that in 2008 is not very high. Judging from the current production situation, some late-sown wheat with poor fertility has a certain degree of frost damage.
According to official forecasts, a weak to moderate La Niña event will begin in December, although the coldest will not arrive until January or February next year.
In addition, according to a meeting held by the China Meteorological Administration, China has suffered from more cold waves and larger cold waves, and the overall temperature in the central and eastern parts of the mainland is generally low, and there is a large temperature difference in a large season.
According to the Central Meteorological Observatory, "cold winter" and "cold winter" are two different concepts, "cold winter" refers to the global average annual temperature, and "cold winter" has its specific critical value. An important factor in judging the "cold winter" is the annual average of the "three months". The official said that the temperature forecast for this winter is likely to drop, but whether it can reach a cold winter depends on this criterion.
The vast number of peasant households should pay special attention to the harm brought by the low temperature climate brought about by the "cold winter" to crops, especially in many places, due to the postponement of planting, slow growth, and poor cold resistance, they should pay close attention to climate changes and do a good job in preventing frost damage.
