台风气压场和风场模式
THE TYPHOON PRESSURE FIELD AND WIND FIELD MODELS

摘要: 关于台风的气压分布,国外有相当多的研究,但绝大多数是作为圆形对称分布来处理.Abstract: In this paper,fujita's and Myers's formulas which have been used only for circular-symmetrical construction of the typhoon are generalized.as a general pressure formula.Their formulae and analogy are valid for different constructions of the typhoon pressure field.To avoid the difficulty of using the maximum wind velocity radius R and the typhoon constant ro,we constructed a general pressure distribution formula without R and r.Using these pressure distribution formulae and the methods of resultant wind velocity for moving typhoon,obtained the wind velocity distribution formulae for stationary and moving typhoons. These formulas are convenient for computations of the pressure and the wind velocity of nearshore typhoons.The computational results are in agreement with the data observed for the pressure fields and wind fields of Nos.7006,7609 and 7613 strong typhoons.
