RSM区域谱模式特征分析

Characteristics Analysis on Regional Spectral Model (RSM)

短期气候的预测对农业生产、农业气象灾害的防御有重要作用。为探索短期气候预测的客观预报工具,引进美国NMC的区域谱模式RSM,并利用该模式对华东地区的短期气候要素进行了预测检验,结果显示:RSM区域模式在地形分布、台风结构、降水等方面的诠释能力较ECHAM 4.5全球模式要好。

Short-term climate prediction was very important to prevent agricultural production and agrometeorological disaster. In order to discuss the objective prediction tool for short-term climate, it introduced regional spectral model （RSM） from American NMC, and used it to detect the short -term climate factors in east China. The result showed that interpretation ability of RSM regional mode was better than ECHAM4.5 global mode in topography distribution, typhoon structure, precipitation and other aspects.
