【摘要】 <正> 一、引言众所周知,海—气相互作用错综复杂,使得海上风的理论计算遇到了许多困难。至今,海上风的估计多半是应用经验统计的方法,即根据气压形势场计算地转风或梯度风,再作有关海面摩擦和大气稳定度的订正。但这种估计误差较大。日益深入开展的数值天气预报与近地面层大气研究为理论上建立数值模式计算与预报海上风场提供了条件。Blachadar(1965)和Cardone(1969)在总结前人研究成果的基础上,先后建立了大气边界层数值模式。国内外学者均曾利用该数值模式进行过海上风场的计算。更多还原

【Abstract】 The Cardone’s model of the atmospheric boundary layer was applied tocalculate the wind field, of cold air and Typhoon influencing the waters of tileStrait. Its mean-square error is 2m/s. This value is 2-5m/s less than the errorof the geostrophic wind or empirical foreast, Based on the observations, wehave revised two empirical coefficients, γ and β, in the general function ofstability. The calculated wind speed in 15m above the sea is better than thatin 10m or 20m.更多还原
