摘要
基于从气候场长期演变提取预测信息的观点 ,从热力学方程和水分平衡方程出发 ,导出了描写地表气温、降水和高度的模式方程组 ,着重考虑了非绝热加热作用和水汽运动形成降水。进一步构造成一个预测区域气候的自忆模式 ,它不同于当今普遍使用的数值嵌套模式。初步计算表明 ,该模式具有较高的预测能力 。
In view of extracting prediction information from long term evolution of climate fields, a model equations of describing variables: surface temperature, precipitation and 500 hPa height was formulated with emphasis on nonadiabatic heating and precipitation from moisture movement. Furthermore, a self memorial model to forecast the regional climate, which differs from the nested model in general use. Preliminary computations indicate that the model demonstrate rather higher skill of predictions, it shows perspective of realizable approach to forecast short term regional climate.
