一、风暴潮数值计算的发展概况 风暴潮数值计算是50年代开始发展起来的。1954年Kivisild用手工计算做过二维流体动力学基本方程组的积分,他模拟了1949年8月25-27日一次袭击美国佛罗里达州的Okeechobee湖的飓风潮,计算结果并不理想,归因于非线性效应。Doodson(1956)亦用手工做过数值积分,算的是外来海平面变化在一均匀渠道中产生的一维风暴潮,他的研究不在于风暴潮本身,而是为了研究天文潮和风暴潮相互作用产生的非线性效应。使用电子计算机作风暴潮数值计算的第一位学者是德国的海洋学家W.Hansen(1956),他对于1953年1月31日至2月1日发生在北海的那次灾难性温带风暴潮作了数值实验,计算是在瑞典斯德哥尔摩的BESK计算机上实现的,计算给出了不少有意义的结果,但是,其中出现了虚假的误差短波,这是由于差分格式不稳定造成的。 60年代初(1961),瑞典著名海洋学家Pierre Welander曾经说过:“从科学的观点看来,风暴潮问题显然很有意义,这将吸引气象学家和海洋学家对此进行深入的研究,看来能从数值预报经验更多地了解海气相互作用。对真实的海气系统机制获得更好的理解,并对用于数值实验的模式取得更好的认识之后,我们必定能发展一种能用于警报服务的准确预报方
First, the development of storm surge numerical calculation storm surge numerical calculation is 50 years began to develop. In 1954, Kivisild calculated the integral of two-dimensional hydrodynamic equations by hand. He simulated a hurricane wave on Lake Okeechobee, August 25-27, 1949 in the United States, and the results were not satisfactory. For non-linear effects. Doodson (1956) also made numerical integration by hand, calculating the one-dimensional storm surges caused by alien sea-level changes in a uniform channel. His research is not on storm surge itself, but on the interaction of astronomical and storm surges Nonlinear effects of action. The first scholar using computer calculations of storm surges was W. Hansen (1956), a German oceanographer who analyzed the catastrophic tempest surges in the North Sea between January 31 and February 1, 1953 A numerical experiment was carried out. The calculation was performed on the BESK computer in Stockholm, Sweden. The calculation gave a lot of interesting results. However, the false shortwave appeared due to the unstable format of the difference. In the early 1960s (1961), the famous Swedish oceanographer Pierre Welander once said: "From a scientific point of view, the storm surge issue obviously makes sense, which will attract meteorologists and oceanographers to conduct an in-depth study , It seems that we can learn more about the air-ocean interaction from the numerical prediction experience, and after gaining a better understanding of the real air-sea system mechanism and gaining a better understanding of the models used in numerical experiments, we will certainly be able to develop a An accurate forecaster that can be used for alerting services
