DoubleHollandWindProfile: Double Holland Wind Profile

Description

McConochie *et al*'s double Holland vortex model based on Cardone *et al*, 1994.This application is the Coral Sea adaptation of the double vortex model and it can also be used for concentric eye - wall configurations.

Usage

DoubleHollandWindProfile(f, vMax, rMax, rMax2, dP, cP, rho, beta, R)

Value

array with two columns for velocity and then vorticity. //@example DoubleHollandWindProfile(-1e-4,20,20,10,980,1.15,1.2,50)

Arguments

f

single coriolis parameter at the centre of TC in hz

vMax

maximum wind velocity calculation in m/s

rMax

radius of maximum winds in km

rMax2

radius of outer radial winds in km

dP

pressure differential, environmental less TC central pressure in hPa

cP

TC central pressure in hPa

rho

density of air in Kg/m3

beta

exponential term for Holland vortex

R

vector of distances from grid points to TC centre in km
