摘要
对引入参考大气和质量守恒律的T63谱模式 1 0年气候积分的结果进行了分析。结果表明 ,模式对全球大气环流有较好的模拟效果 ,对中国地区地面气温和中国东部地区的降水也有一定的模拟能力 ,其中对气温的模拟效果好于降水。模拟存在着一些误差 ,对地面气温 ,主要是模拟的温度场系统性偏低 ,不能模拟出小地形波动引起的温度变化 ;对降水的模拟 ,为在我国中西部模拟出了一个大的虚假中心。
year simulation of T63 model driven by climate sea surface temperature with application of mass conservation law only was analyzed. It indicates that the model can simulate well the global scale atmosperic circulation. The model also reproduced the basic patterns of air surface temperature in China and precipitation in east part of China, with a better performane in simualting air surface temperature than precipitation. But the model tends to have a cold bias in simulating air surface temperature, and it can not desrcibe the small air surface temperature perturbations caused by topography. As for precipitation, a big virtual center was simulated in mid-west part of China.
