1911年,英国气象学家理查森提出用数值计算的方法来研究气象过程,并进行预报。他建议以现在时刻的气象动力参量作初始值,用数值方法逐步地解算气流运动方程来定出气象动力参数的演变。在当时,上述建议是不现实的。因为气象运动方程是一组非线型偏微分方程,问题的规模与复杂性极大。用人工操作的计算工具,解算一个24小时天气预报问题,也得算上几个星期,那时业已明日黄花,失去时效了。但是,理查森是有其真知灼见的。他懂得,象气象运动方程这样的复杂非线性偏微分方程组,是不可能指望用数学理论的方法来求解的,只能设想用计算的方法来解决。他期待着有朝一日计算速度能超过天气的变化。他预感到,计算上升为一种主要的科学方法的时代即将来临。
In 1911, British meteorologist Richard Richardson proposed a numerical method to study the meteorological process and forecast it. He suggested that the meteorological parameters at the present time be used as initial values, and numerical equations should be used to solve the evolution equations of the aerodynamic parameters step by step. At the time, the above proposal was unrealistic. Because the meteorological equations of motion are a set of nonlinear partial differential equations, the scale and complexity of the problem are enormous. Calculating a 24-hour weather forecast problem with manually operated calculation tools has to be counted for a few weeks, when the already bright yellow flower is already out of date. However, Richardson has its own insights. He understands that complex nonlinear systems of partial differential equations such as meteorological equations of motion can not be expected to be solved using mathematical theory and can only be conceived of using computational methods. He looks forward to one day counting how much faster the weather can change. He foretold that the era of computing as a major scientific method is approaching.
