气旋在黑潮海域的异常发展早已为许多作者所注意。目前从统计学和动力学方法也已证实,东海气旋的异常发展与黑潮海域充沛的热量供应有关。有的作者试图从海面能量供应的角度论证上述事实,如Ninomiyo曾以半经验的方法计算黑潮海域气旋式波动的有效位能的转换。但对气旋的发生发展而言,更重要的是扰动有效位能的生成及其转换。然而迄今未见有关于黑潮对气旋扰动能量关系的详细计算和讨论。本文在计算了黑潮上空气旋区海面和高空微尺度的热涡动输送值后,着重讨论了海洋热源引起的气旋区扰动有效位能的产生及其转换。作为对照,也计算了气旋在陆地和移出黑潮区以后的扰动能量平衡。我们试图从所得结果分析气旋在陆地、海洋和黑潮
The abnormal development of cyclones over the Kuroshio has long been noted by many authors. At present, statistics and kinetic methods have confirmed that the abnormal development of the cyclone in the East China Sea is related to the abundant heat supply in the Kuroshio. Some authors attempt to demonstrate the above facts from the perspective of sea energy supply. For example, Ninomiyo used a semi-empirical method to calculate the conversion of effective potential energy of cyclonic fluctuations over the Kuroshio. But for the occurrence and development of cyclones, what is more important is to disturb the generation of the effective potential energy and its transformation. However, no detailed calculation or discussion on the relationship between the Kuroshio energy and the disturbance of cyclone energy has been found so far. In this paper, after calculating the value of the heated eddy convection on the microscopic scale of the surface of the cyclone over the Kuroshio, the generation and transformation of the effective potential energy of the cyclone disturbance caused by the marine heat source are mainly discussed. As a control, the disturbance energy balance of the cyclone after landfalling and removing from the Kuroshio area was also calculated. We try to analyze the cyclone results from the land, sea and Kuroshio
