hus850: specific humidity [lon, lat, time] at 850 hPa (kg/kg).
ta500: air temperature [lon, lat, time] at 500 hPa (K).
ws850: wind speed [lon, lat, time] at 850 hPa (m/s).
wd850: wind direction [lon, lat, time] at 850 hPa (degree; 0 - 360).
ws500: wind speed [lon, lat, time] at 500 hPa (m/s).
wd500: wind direction [lon, lat, time] at 500 hPa (degree; 0 - 360).
nthreads: an integer specifying the number of threads to use for computation (OpenMP). Default is 1.

Value
