sinlat

sinlat(fs)

Returns the fieldset of the sine of the latitude of fs at each grid point.

Missing values are retained, unaltered by the calculation.

Example

The following code shows how to compute the absolute vorticity from vorticity with sinlat():

import metview as mv
import math

omega = 2 * math.pi / 86400
coriolis = 2 * omega * mv.sinlat(vort)
absvort = vort + coriolis
