葫芦岛沿海地区最高气温变化的影响因子分析

摘要

该文利用欧洲中心数值模式资料、Micaps常规观测资料、地面自动站逐时观测资料，对2009年5月19日影响葫芦岛沿海地区高温的气象因子进行了分析。结果表明，由于海陆热力差异的存在，风向对葫芦岛沿海地区夏季温度的变化起着决定性作用，直接关系着夏季高温能否出现；多云的天气现象亦是引起温度变化的重要原因。%In this paper,through the European Centre for the numerical model data,Micaps conventional observation data and observations by the ground station automatically,effect of meteorological factors on the high temperature of Huludao coastal area in May19,2009 were analyzed. The results show that the presence of land-sea thermal con⁃trast,wind direction plays a decisive role in the change of summer temperature in Huludao coastal area,directly relat⁃ing to the summer heat,and cloudy weather is also an important cause of temperature change.
