Based on the meteorological observation data of three meteorological stations in three major chemical industrial parks of Lianyungang city( Xuwei petrochemical industrial park-Xuwei saltern automatic weather station,Yanweigang chemical industrial park-Yanweigang automatic weather station,and Lianyungang chemical industrial park-Duigou chemical industrial park automatic weather station) as well as lightning data of Jiangsu thunder and lightning monitoring network from 2007 to 2014,meteorological environmental factors(wind,temperature and lightning) in the three major chemical industrial park of Lianyungang City were analyzed,and climate feasibility demonstration was conducted. In this paper,the common points of the meteorological environment of construction projects in the three major chemical industry parks were obtained,and the planning,design and operation of chemical projects were advanced reasonably according to different meteorological environment,thereby maximizing social and economic benefits.
