【摘要】 <正>自从V.W.Ekman提出著名的风漂流理论,以及B.Helland-Hansen提出著名的梯度流公式以来,海流理论获得了极其迅速的发展。K.Hidka and Y.Akiba,J.J.O’Brienand R.O.Reid,J.E.Geisler,B.丑.Ry~oB,C.Cooper and B.Pearce等已经做了十分有意义的台风流的现场观测、数值模拟和理论研究工作。 本文为台风海流研究的初始阶段结果。其目的在于,探讨轴对称定常台风作用下的海流结构,从而使我们对它的流速和水温的空间分布,有些探索性的了解。更多还原

【Abstract】 Axis-symmetrical typhoon-generated ocean currents are studied. The relevant equation system is first solved, and then the distributions of sea surface elevation, wind-driven current, geostrophic current and sea water temperature are described.The main conclusions drawn from this investigation can be summarized as follows:1. Upwelling of deep water and rising of sea surface occur inside a circlewith the radius of 2R, where R denotes the distance from typhoon center to the location of maximum wind speed.2. Circulations at the surface layer are of cyclonic pattern, while those at the subsurface layer of anticyclonic pattern.3. The lowest temperature of sea water occurs along the circumference with the typhoon center as its center and R/2 as its radius.4. The wind-driven current dominates at the Ekman layer and under this layer the. geostrophic current plays a more significant role.更多还原
