NewHollandWindProfilePi: New Holland Wind Profile Time Series

Description

Wind profile time series at a grid point. Holland et al. 2010. In this version, the exponent is allowed to vary linearly outside the radius of maximum wind. I.e. rather than take the square root, the exponent varies around 0.5.Currently this version does not have a corresponding vorticity profile set up in wind Vorticity, so it cannot be applied in some wind field modelling.

Usage

NewHollandWindProfilePi(f, rMax, rMax2, dP, rho, R, vMax, beta)

Value

array with two columns for velocity and then vorticity. //@example NewHollandWindProfilePi(-1e-4,20,20,1.15,-14,50,1.3)

Arguments

f

single coriolis parameter at the centre of TC in hz

rMax

radius of maximum winds in km

rMax2

radius of outer 17ms winds in km

dP

pressure differential, environmental less TC central pressure in hPa

rho

density of air in Kg/m3

R

vector of distances from grid points to TC centre in km

vMax

maximum wind velocity calculation in m/s

beta

exponential term for Holland vortex
