摘要
本文提出了一个非静力平衡中小尺度数值模式,在模式中包含云的微物理学参数化方案、地面温度和水温预报方案、边界层湍流参数化方案、长波和短波辐射参数化方案,且包含地形。模式具有较好的积分稳定性,能精确地模拟边界层内气候的演变过程。本文用该模式研究了陆地水体对温度、湿度、风和湍流强度的影响,模拟结果与实测资料一致,反映了陆地水体对周围气候环境的影响过程和规律。
Developed here is a non-hydostatic mesoscale numerical model for simulating the effects of the inland water body on climate. The model comparises the microphysical parameterization of clouds, the prediction schemes of the surface temperatures both on ground and on water surface, the parameterization of the turbulent exchange coefficient in the planetary boundary layer (PBL), and the calculation schemes of long and short wave radiations. It can simulate precisely the change process occuring at the PBL, the effects of non-adiabatic heating on the atmosphere, the effects of inland water body on temperature, humidity, wind, cloud, precipitation and the turbulent exchange coefficient. It may also be used for the studies about urban, mountain, agriculture, water, desert and green islands climates, in general those affected by the change of ground surface. It may also precisely reproduce the lake-land breezes and valley-mountain breezes. The simulated results are in good agreement with the field observations and other studies.
