About this snowstorm
For China, there are two factors that cause large-scale heavy precipitation: 1, cold air 2, and warm and humid airflow in the southeast and southwest. Only when these two points have the same influence will the above situation occur.
It should be said that the most direct reason for the occurrence of such a wide range of low temperature anomalies in rain and snow is the anomaly of atmospheric circulation system, especially since June+10 in 5438, the circulation in the middle and high latitudes is mainly meridional, with frequent cold air activities. In addition, the subtropical system is strong, northwest than normal, which is conducive to transporting warm and humid air from the south to the north. On the one hand, the cold air in the north is very active, on the other hand, the warm and humid airflow in the south is constantly transported northward. The intersection of cold and warm air flow is mainly located in the central and eastern regions of China, which creates favorable circulation conditions for large-scale rain and snow weather. In meteorology, this circulation anomaly is generally attributed to two reasons. On the one hand, it is determined by the motion law of the atmosphere itself, on the other hand, it is influenced by external compulsion. This year's circulation anomaly is related to the La Nina event in August 2007.
