McConochie Wind Field Time Series

Description

Time series vortex Wind, wind vectors. McConochie, J.D., T.A.Hardy and L.B.Mason, 2004: Modelling tropical cyclone over - water wind and pressure fields. Ocean Engineering, 31, 1757 - 1782.

Usage

McConochieWindFieldPi(rMax, vMax, vFm, thetaFm, Rlam, V, f, surface)

Arguments

rMax

radius of maximum winds in km

vMax

maximum wind velocity calculation in m/s

vFm

input forward velocity of TC

thetaFm

input forward direction of TC

Rlam

two columns for distances and direction from grid points to TC centre in km

V

velocity profile

f

coriolis parameter at the centre of TC in hz

surface

equals one if winds are reduced from the gradient level to the surface, otherwise gradient winds.

Value

array with two columns for zonal and meridional wind speed vector-components. //@example McConochieWindFieldPi(-1e-4,20,2,10,rbind(c(50,35),c(45,40)),c(20,20))
