【摘要】 本文提出数值求解混合型平衡方程的一种逐步变型—轮换—迭代方法。引进外迭代因子。实例计算表明,用这种方法解出的流函数反解出高度场无系统性降低和副热带高压减弱消失等现象。适合应用来提供我国低纬度地区的数值天气预报模式的初值。将平衡方程作为混合型方程求解,目前还是新的首次试验。更多还原

【Abstract】 In this paper, a numerical method for solving the mixed type balance equation is proposed. The procedure is to run cyclic scans and iterations with successive transformation of the types. In order to test its accuracy, the balance equation is solved inversely to get inverted geopotential field from stream functions obtained. No systematic error in geopotential field is observed, which suggests that the method could be used in low latitudes.更多还原
