The cold air will get stronger around January next year, and there may be heavy snow and ice in the north. |
On November 4, the China Meteorological Administration held a press conference to introduce the major weather and climate events of October and the forecast of autumn and winter weather trends.
According to Feng Ling, deputy director of the Department of Emergency Mitigation and Public Service of the China Meteorological Administration, compared to the same period of normal years, the weather and climate in October this year showed the following characteristics: more typhoons were generated and a strong tropical storm landed in China; autumn rains in western China triggered Gan and Sichuan. Geological disasters like landslides occurred in local areas like Hubei and Hubei; there were 4 cold air processes that affected China.
Feng Ling said that in November, the temperature in the north is expected to be higher in the east and lower in the west, with less rainfall in most of the country, and less obvious in eastern northern China, the east of Huanghuai and Jianghuai.
“In the next 10 days, precipitation in most parts of the country will be significantly less and the forces of cold air affecting our country will be weak.” Feng Ling recalled that in the next 10 days there will be more typhoons in the South China Sea and the Pacific Northwest. In addition to “Swan” and “Aishani”, there will be 1 to 2 typhoons in the South China Sea and the Pacific Northwest, one of which will affect the South China Sea.
Regarding the overall climate trend in China this winter, Jia Xiaolong, deputy director of the National Climate Center, said that recently, relevant business research institutes and experts from national universities engaged in climate research have discussed climate trends this winter. According to the opinion of the current consultation, the cold air that affects our country is relatively frequent this winter, and the force of the cold air is generally stronger.
Also, the cold air route that affects our country this winter is mainly the northwest route. In such a general situation, this winter, except in the areas of the plateau and the east coast of the northeast, which are slightly warmer, the temperature in most other areas is normal to low. “The overall precipitation situation is more in the north and less in the south. Due to the influence of ‘La Niña’, the water vapor transport conditions in the south are generally skewed and precipitation is less,” said Jia Xiaolong.
He noted that the phases of climate change in China this winter are very obvious, especially changes in temperature. In early winter, except for low temperatures in western Inner Mongolia, northwest China, and southern China, the temperature in most areas of the country was normal to high.
He recalled that around January of next year, the forces of cold air that will affect our country will obviously get stronger. The temperature in the central and eastern regions and most areas will be lower than usual, and there may be a relatively strong ice and snow climate in the northern region. Take precautions. “Affected by the ‘La Niña’ in the southern region, a wide range of continuous rain and snow at low temperatures is less likely to occur this winter, but in the eastern part of the southwest and western part of Jiangnan, there will still be rain and staggered snow in winter “. Jia Xiaolong Say.
Jia Xiaolong also said that weather prediction itself is very difficult and it is also a global problem. Changing factors and factors affecting climate are complex, from tropical regions to high latitude polar regions, these factors interact and make climate prediction difficult and uncertain.
“While strengthening our understanding of climate laws and mechanisms, we are also developing some climate prediction methods. We will also carry out timely monitoring and consultation in the after-period to provide prediction opinions of continued climate trends,” said Jia Xiaolong.
