珠江口高分辨率下垫面特征的气象学分析

Meteorological Comprehension of High Resolution Land Classification over the Gate of Pearl River and Its Neighborhood

借鉴国际上较通用的下垫面特征分类标准，结合珠江口邻近地区下垫面的实际情况，对珠江口邻近地区的下垫面特征（包括地形高度、地表特征和土壤特征）进行归纳分类，形成了１ｋｍ×１ｋｍ高分辨率的下垫面特征的格点化资料，可供该地区陆气相互作用和数值天气模式的研究使用．

The related data of underlying surface at home and abroad and the common criterions of land use classifications were utilized, the actual conditions were also combined, underlying surface features, including terrain elevation, land use and soil feature, over the gate of Pearl River and its neighborhood,were comprehended into grided data with high resolution(1 km×1 km).It is useful for the investigation of air land interaction and the simulation of numerical weather model.
