calc_forward_speed: Calculate storm's forward speed

In stormwindmodel: Model Tropical Cyclone Wind Speeds

Description

This storm takes two storm locations and their observations times and calculates the average speed of the storm between the two observations.

Usage

calc_forward_speed(tclat_1, tclon_1, time_1, tclat_2, tclon_2, time_2)

Arguments

tclat_1	A numeric vector giving latitude of the first location (degrees)
tclon_1	A numeric vector giving longitude of the first location (degrees). This value should be expressed as a positive value for Western hemisphere longitudes.
time_1	A date-time vector giving the time of the first observation.
tclat_2	A numeric vector giving latitude of the second location (degrees)
tclon_2	A numeric vector giving longitude of the second location (degrees). This value should be expressed as a positive value for Western hemisphere longitudes.
time_2	A date-time vector giving the time of the second observation.

Value

A numeric vector with the average forward speed of the storm between the two observations, in meters per second.
