Vertically Integrated Moisture Flux Divergence (VIMFD)

Usage

VIMFD(hus, ua, va, lon, lat, pa_pl, nthreads = 1)

Arguments

hus: specific humidity [lon, lat, lev, time] on pressure levels (kg/kg).
ua: zonal wind component [lon, lat, lev, time] on pressure levels (m/s).
va: meridional wind component [lon, lat, lev, time] on pressure levels (m/s).
lon: longitude coordinates [lon] (degrees east).
lat: latitude coordinates [lat] (degrees north).
pa_pl: pressure levels [lev] (hPa).
nthreads: an integer specifying the number of threads to use for computation (OpenMP). Default is 1.

Value

array [lon, lat, time] the computed VIMFC (kg m^-2 s^-1).

Examples

data("ERA5_pl")
hus <- ERA5_pl$hus
ua <- ERA5_pl$ua
va <- ERA5_pl$va
lon <- ERA5_pl$lon
lat <- ERA5_pl$lat
# to hPa
pa_pl <- ERA5_pl$plev / 100
# VIMFD
res <- VIMFD(hus, ua, va, lon, lat, pa_pl, nthreads = 1)
