在中尺度区域气候模式RIEMS中通过考虑和不考虑辐射对大气温度变化的影响来研究中尺度气象过程对辐射的敏感性。结果表明,在月尺度上,辐射可以引起平均约2℃的温度差,从而影响气压形势场和中尺度气象过程,进而影响降水。但在日尺度上,辐射的作用可以不计。
The sensitivity of moso-scale model to radiation is studied by including and omitting the variation of atmospheric temperature caused by radiation in the meso-scale regional climate model RIEMS. The results show that for month time-scale, the radiation can cause an order of magnitude 2C for mean temperature difference, inducing the differences of pressure situation, meso-scale meteorological process, finally, the precipitation. But for day time-scale, the effect of radiation can be neglected.
