“130318”渤海强风天气成因分析
Analysis of the causes of the march 18, 2013 gale process over the Bohai sea
摘要
Abstract
By using automatic meteorological observation station data,conventional observation data and NECP data with 1°× 1° resolution,a gale process occurred on March 18th,2013 in Bohai Sea and the causes of the gale are analyzed.The results show that the gale is caused by the cold front.During the process of gale,a transmission path for the cold advection from top to bottom is formed,and the cold air is transported into the low level rapidly which leads to strong cold advection near surface.The allobaric wind caused by severe pressure swing is another important reason for gale accompanied by the coming of cold air mass.Besides,the intensity of cold front which leads to gale,is strengthened by increasing temperature occurring before the arrival of cold front.The downward momentum transportation resulting from the secondary circulation crossing the cold front also play an important role in the instantaneous strong gust.关键词
