Description

Calculate distance between two latitude / longitude points

Usage

calc_distance(tclat, tclon, glat, glon, Rearth = 6371)

Arguments

tclat	A numeric value with the latitude of the tropical cyclone's center in radians
tclon	A numeric value with the longitude of the tropical cyclone's center in radians
glat	A numeric value with the latitude of the grid point in radians
glon	A numeric value with the longitude of the grid point in radians
Rearth	A numeric value with the radius of the earth in kilometers. This value defaults to 6,371 km, which is the median radius of the earth.

Value

A numeric value with the distance (in kilometers) from the tropical cyclone center to the grid point.
