Radial Profile of the Surface Wind in the Typhoon-area

概要

論文の詳細を見る
It is attempted in this paper to obtain the model of the radial wind profile within a typhoon whose position (latitude φ) and whose pressure (P_o, P_R ) and wind (V_o,' V_R) at the inner radius r_0 and at the external radius R are known. The model introduced here does not require the data of r_0 because the boundary condition to be satisfied by the model yields the value of r_0 as a function of other knowns (φ, R, V_R , P_R , V_o , and P_0). The pressure profile is also automatically derived from the obtained wind profile. The validity of the model is checked by applying it for the cases of two typhoons. The computed wind and pressure radial distributions are generally supported by the available observational data, excepting the cases in which input data of V_0 are not appropriately selected for computation.
