Function to calculate model wind direction

Description

Function to calculate model wind direction

Usage

uv2wd(u, v, verbose = TRUE)

Arguments

u	data.frame with model time-series of U10
v	data.frame with model time-series of V10
verbose	display additional information

Value

vector or data.frame with time and the wind direction, units are degree north

Examples

times <- seq(as.POSIXct('2024-01-01',tz = 'UTC'),
             as.POSIXct('2024-01-02',tz = 'UTC'),
