HubbertWindFieldPi(f, rMax, vFm, thetaFm, Rlam, V, surface)
f |
single coriolis parameter at the centre of TC in hz |
rMax |
radius of maximum winds in km |
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 |
surface |
equals one if winds are reduced from the gradient level to the surface, otherwise gradient winds. |
array with two columns for zonal and meridional wind speed vector-components. //@example HubbertWindFieldPi(-1e-4,20,2,10,rbind(c(50,35),c(45,40)),c(20,20))
