摘要
研制了一个包括水平及垂直扩散、牛顿冷却的二维 46层非弹性运动方程组的台湾海峡海陆风数值模式 ,并用此模式来模拟及研究台湾海峡两岸海陆风的生成与变化特征。模式中考虑了太阳辐射、长波辐射及其日变化、地表向大气的感热与潜热输送以及向土壤层的热传导等。数值计算中采用了分解算法及隐式时间差分方案。用此模式得出的模拟结果与闽东南及台湾海陆风的观测事实比较吻合 ,表明了此模式能够较好地描述海峡两岸的海陆风变化规律。
In this paper, a two-dimensional 46-level numerical inelastic model of the land and sea breeze with the horizontal and vertical diffusion and the Newtonian cooling is designed and used to simulate and investigate the formation and the variations of the land-sea breeze over the Taiwan Strait. The numerical model consists of solar radiation, long-wave radiation and their diurnal variations, upward sensitive and latent heating on the surface, and thermal conductance in the soil layers, etc. Splitting method and implicit time difference scheme are used in the numerical calculation. And the simulation results are consistent with the observations, indicating that the numerical model can describe the variation features of the land and sea breeze over both coasts of the Taiwan Strait.
