Weather forecast 202 1 1

Around 1, the cold air force becomes stronger, and there may be strong snow and ice weather in the north. Jia Xiaolong, deputy director of the National Climate Center, responded on the 4th that by June of next year, the cold air force affecting China will become stronger obviously, the temperature in the central and eastern regions of China is lower than normal, and there may be strong snow and ice weather in the north, so attention should be paid to prevention.

The stage of climate change in China this winter is very obvious, especially the temperature change. In early winter, except for the low temperature in western, northwest and southern Inner Mongolia, the temperature in most parts of the country is still normal to high. Around June 5438+ 10 next year, the cold air force affecting China will become stronger obviously, and the temperature in the central, eastern and most areas will be lower than normal.

There may be strong snow and ice weather in the northern region, so take precautions. Affected by La Nina, it is unlikely that there will be a large-scale continuous low-temperature rain and snow freezing in the south this winter. However, in the eastern part of Southwest China and the western part of Jiangnan, there will still be staged rain and snow weather in winter.

Extended data

The distribution of global marine continents, including the pattern of land topography and mountains, plays an important role in the formation of climate. For example, the Qinghai-Tibet Plateau plays a very important role in the formation of monsoon climate in East Asia. From the point of view of Qinling Mountains, its scale is much smaller than that of Qinghai-Tibet Plateau. The barrier height of the Qinling Mountains is about 3,000 meters, and the Qinling Mountains in a broad sense can reach thousands of kilometers.

Its uplift has a certain blocking effect on the airflow, on the one hand, it can block the cold air from the north to the south, on the other hand, it can also block the water vapor from the southern tropical region from being transported to the north. No matter how small the mountains are, they also have an impact on the local weather and climate. In its scale range, it can have a certain impact on the airflow, but the cold air beyond the scale range may not be able to stop it.

People's Daily Online-The cold air will become stronger around June 5438+ 10 next year, and there may be strong snow and ice weather in the north.
