Compared with the same period of normal years, the northeastern and western parts of Inner Mongolia, Heilongjiang, Gansu, northern and eastern Qinghai, northern Sichuan, southeastern Guangxi, Hainan, most of Guangdong, and most of Xinjiang had more precipitation, and the rest of the country had precipitation close to the same period of normal years. To less.
The temperature in the north is higher in the east and lower in the west.
In the next 10 days, the average temperature in most parts of the country will be higher than normal. Among them, the temperature in most parts of Northwest China, northern North China, Northeast China and western Yunnan will be 2 to 3°C higher.
[Explanation] Winter 2020 is approaching, what is the overall climate trend?
In this regard, experts said that at present, the cold air in the winter of 2020 is generally more frequent, and there may be strong snow and ice in the northern region during the mid-winter period.
[Concurrent] Jia Xiaolong, Deputy Director of National Climate Center
In the winter of this year (2020), the temperature in most parts of our country is normal to low. Except for the northeast, eastern coastal and plateau regions, which are slightly warmer, in addition, the winter climate of our country this year (2020) The stage of change is very obvious, especially temperature changes.
In the mid-winter season, around January next year (2021), the cold air force affecting our country will obviously become stronger. The temperature in the central and eastern regions and most areas of our country may be lower than usual, and the northern region may have a larger range. Take precautions against this big ice and snow weather.
[Explanation] Heating in the north is about to usher in, haze and air pollution have attracted much attention.
What are the atmospheric diffusion conditions in the winter of 2020?
In response, experts also responded.
[Concurrent] Jia Xiaolong, Deputy Director of National Climate Center
In the winter of this year (2020), the winter monsoon is generally slightly stronger. The circulation (condition) in the middle and high latitudes is that the cold air is more frequent and the forces will generally be stronger.
Under such conditions, it is expected that the meteorological conditions for the spread of air pollution in winter this year (2020), such as the Fenwei Plain and the surrounding areas of Beijing-Tianjin-Hebei, are generally close to the average (level) of the past five years.
The Yangtze River Delta region is slightly off the average (level) in the past five years.
Overall, we think that the three regions may be closer to 2017 and 2018.
Although the cold air activities are more frequent this year, this kind of polluted weather should be paid more attention to during the intermittent period of cold air activities.
