[HIGHLIGHTS] Four questions about rare snowfall in the north: continuous snow for many days and deep records Why is there such heavy snowfall in April?

Since April 4, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi and other places have seen snowfall or rain turning snow. Snowfall adversely affects facilities, agriculture, economy, forestry and transportation.

Strong cold air combined with strong southerly warm and humid airflow, as well as easterly return flow to transport water vapor, forming a wide range of rain and snow weather during the intersection of cold and warm currents. There may be some light snow or sleet in eastern Qinghai, southern Hebei, central and eastern Inner Mongolia today.
