摘要
Abstract
By using NCEP FNL, ECMWF forecast, NMWW3 hindcast data and facsimiles from JMH, the comparative analysis of two cases of cold air was carried out. By investigating the weather situation and impact on the Western North Pacific (WNP) intensively, the essential distinctions were revealed. The results are shown as follows: (1) The long-wave trough holding in the climate position of East Asia major trough is in favor of the burst of poor sea condition in the WNP; (2) The Southern branch trough developing in the Bay of Bengal results in the subtropical high ridge enhancing and westward extending in its downstream half wave length position, which will strengthen the upper southwest airflow in Eastern China; (3) ECMWF provides reasonable 96- and 168-hour weather prediction for the two cases of cold air, and also the 240-hour surface sea level prediction was useful for the reference.关键词
