A Numerical Research on the Influences of the Diurnal Variation of Solar Radiation on the Medium-Range Weather Processes

In this paper, we use a spectral model for the medium-range numerical weather forecast to discuss the impact of the diurnal variation of solar radiation on the medium-range weather processes. Under the tests of two typical winter and summer cases, we find that the influences of the diurnal variation of solar radiation on summer weather are really important, especially on its rainfall, surface heat transport and 500 hPa height field. On winter weather, however, the influences are very weak.     

冬季亚洲大陆冷高压形成和发展过程的数值模拟

本文利用一个包括辐射、陆地的热量平衡，雪量的变化以及对流凝结和大地形的作用的两层球谱模式，模拟了冬季亚洲大陆冷高压的形成和发展过程。文中给出了大陆冷高压在源地形成、南侵和入海变性三个阶段的海平面气压场，对流层中部的温度场结构和垂直运动场特征，其结果与观测事实相一致。并模拟出冷高压发展所引起的副热带和热带行星尺度环流的变化。
