| 摘 要： | 利用大理国家气候观象台建立的大气边界层（PBL）观测系统探测资料,详细分析了2010年1月15日云南大理日环食期间辐射通量、气温以及相对湿度的变化情况。结果表明：日环食过程中,太阳短波辐射和气温均表现出＂V＂型分布,而相对湿度呈现倒＂V＂型分布。太阳短波辐射从初亏时开始减小,食甚时达到最小值,复圆时恢复正常,与理想晴天条件下相比,食甚时亏损率高达88%。由于到达地表太阳辐射强度的减弱,地面有一个冷却作用过程,引起地面气象要素的一系列变化,越接近于地表变化越明显,所引起气温、相对湿度的变化时间滞后于日环食时间。

| Abstract: | Based on the observational data of the planetary boundary layer observation system developed in Dali national climatic observatory,variation characteristics of the solar radiation,air temperature and relative humidity were analyzed during annular solar eclipse occurred on 15 January 2010 in Dali.Results indicated that downward shortwave radiation and air temperature showed the variations of the V type in the annular solar eclipse process,but relative humidity showed the variations of the inverted V type.Dow... |
