atan2

Hello everybody,

I want to calculate the meteorological wind direction given the zonal (u) and meridional (v) wind components with the following formula

wind direction = (180/pi) * atan2(u,v) + 180

The zonal (u) and meridional (v) wind components were simulated with the regional climate model REMO and are defined at the edge of the grid box. Is it necessary to interpolate the zonal (u) and meridional (v) wind components so that they are defined in the middle of the grid box?

Best regards

Stephan
