ABSTRACT: To help
the forecast of cold weather activity, the cold weather process in the North China from October 20 to 23, 2020
was analyzed by the methods of utilizing statistical analysis, such as composite, differential analysis and correlation
analysis, and by using the data from the National Meteorological Information
Center of China, the National Climate Center of China and the NECP data from
NOAA Physical Sciences Laboratory. The results show that: 1) the cold air
started from Siberia, took the east path to move southward, and finally
affected most part of North China. 2) Almost no obvious weather occurred during
the process. 3) The cold air mainly moved along with the form and
development of the trough and ended when the trough got weaken.
