摘要
利用1961—2010年云南124站年平均资料,在考虑了气象要素垂直递减(增)率的条件下,将站点数据插值到1 km×1 km的细网格点上。在此基础上,从不同气候带的角度讨论了地面气象观测站点的布局问题,给出了一些有价值的论据。通过分析发现,金沙江流域、怒江大峡谷狭长区域、哀牢山纵向岭谷地貌区域(包括元江、无量山一带)为气象要素最不敏感区域,其主要原因是气候带的南北向分布和东西向剧烈变率。这些区域新增地面观测站点,对认识局地立体小气候、下垫面热力差异、强对流天气系统等有科学价值。
The 1 km resolution＇s fine-grid data was interpolated which is based on the annual mean data from 1961 to 2010 of 124 weather stations in Yunnan province and the vertical variety rates of mete- orlogical elements. On this basis, this paper discussed the layout of the weather stations in terms of cli- mate zone and put forward some valuable arguments. The analysis showed that these regions like Jinsha River basin, gorge area of Nujiang River and Longitudinal Range-Gorge region of Ailao Mountain （ inclu- ding the region of Yuanjiang and Wuliang Mountain） are most insensitive to the meteorlogical elements. This feature can be explained by the distribution difference between north-south direction and the signifi- cant variability in east-west direction in climatic zone. The increase in observation stations in these regions leads to improved understanding of local three-dimensional micro-climate features, surface ther- mal differences, severe convective weather, etc.
