wflux: Takaya Nakamura Wave Activity Flux

In santiagoh719/ClimFunctions: Functions For Climate Data

Description

Compute the Takaya Nakamura Wave Activity Flux.

Usage

  Takaya_Nakamura_Flux (GPH, U, V, lat, lon, lev,
                        lat_lon = TRUE, spherical_x = FALSE,
                        a = 6371000, rad = FALSE)

Arguments

GPH	2D array of the geopotential heigth anomaly
U	2D array of the zonal wind climatology
V	2D array of the meridional wind climatology
lat	numeric vector of the latitudes of the data
lon	numeric vector of the longitudes of the data
lev	numeric, vertical level in hPa
lat_lon	logical, is the data dims organize lat_lon (default), if are lon_lat use =FALSE
spherical_x	logical, is the x axis continous (after the last value comes the first one) ? default = FALSE
a	numeric, redius of the Earth in meters default = 6371000
rad	logical, are the latitude and longitude in radians ? default = FALSE

Details

Takaya_Nakamura_Flux compute the Wave Activity Flux propoused by Takaya and Nakamura (2001).

Value

Returns a list with the X and Y components of the wave activity flux.

Flux_x

Component of the x axis

Flux_y

Component of the y axis
