MagnitudeAzimuth: Convert zonal-meridional wind speeds to magnitude/azimuth.

Description

Given zonal (East-West) and meridional (North-South) wind speeds, calculate magnitude of wind vector and azimuth from north, in degrees.

Usage

MagnitudeAzimuth(zonal.wind, meridional.wind)

Value

winds$magnitude

Magnitude of wind vector.

winds$azimuth

Azimuth of wind vector in degrees from North

Arguments

zonal.wind

A vector of zonal (East-West) winds, west negative.

meridional.wind

A vector of meridional (North-South) winds, south negative.
