【摘要】 本文以流体动力学模拟实验的方法,初步揭示了青藏高原地形,对移到高原南侧25°N附近的孟加拉湾热带气旋的地形效应.这种大地形的动力作用,对以不同路径靠近高原的孟加拉湾热带气旋的影响是不同的. 我们给出了三种不同路径移近高原的孟加拉湾热带气旋的上、中、下层水平流场及垂直剖面结构,并计算了它们在上述各层的风速径向分布.更多还原

【Abstract】 By making use of fluid dynamical simulation, the tropical cyclones over the Bay of Bengal to the south of the Plateau and near 25癗 are preliminarily studied. This dynamic effect of the huge topography is variable in terms of various tracks of the tropical cyclones over the Bay of Bengal which approach the Plateau.We have presented the horizontal flow patterns at the low, middle and upper levels and the vertical cross-sections for three tracks of the tropical cyclones approaching the Qinghai-Xizang Plateau and estimated the radial profiles of wind speed.更多还原
