摘要
本文首先改进了陆地下垫面特征非均-性的次阿格尺度参数化方法，然后利用三维地气耦合的区域气候模式，设计一系列数值试验，研究了下垫面特征改变对区域气候环境变化的影响，主要分析了陆地表面特征变化对我国苏南附近地区夏季温度变化的影响，结果表明采用陆地下挚面特征非均一作用的次网格尺度参数化方法对于改进数值模拟结果的质量有一定效果。
A parameterization scheme of heterogeneous subgrid -scale land surfaces has been improved first in this paper, then a series of sensitivity experiments have been conducted andthe effects of land surface changes on regional climate environment are investigated by usingan earth-air coupled regional rpodel. The focus was on the temperature variation resultedfrom land surface changes over southern part of Jiangsu Province. It is found that this parameterization scheme can improve modeling results in some extent and the results are closeto observational data.
