| 摘 要： | 本文建立了一个三维中尺度模式,分别模拟了平坦地形及规则山地情形下冷空气爆发过程,并模拟了无冷空气时天气演变过程作为比较.模拟结果合理地给出了冷空气爆发后边界层内诸要素的变化规律,如大风的出现、风向的改变、动量通量的增大、气压的升高等.

| Abstract: | A three dimensional numerical meso-scale model was developed to simulate cold-air outbreak processes over underlying surface with plain and regular terrain. The weather change processes without the cold-air were also simulated for comparison. The result show reasonable phenomena, such as strong wind , the change of wind direction , the abrupt increase of the momentum flux and pressure , ect. |
