Reverts speed and direction to U and V components.
This function calculates U (i.e. zonal or east/west) and V (i.e. meridional or north/south) components from a specified speed and direction.
A numeric value indicating speed.
A numeric value indicating direction in degrees from north or radians if
A logical indicating whether
This function calculates U (i.e. zonal or east/west) and V (i.e. meridional or north/south) components from a specified speed and direction. U and V components describe the direction into which movement occurs with east and north being positive, respectively. If directions are given in radians,
radians must be set to
data.frame containing U and V components given in the same units as
