computeTEW.list: Compute the topographic exposure to wind

In StormR: Analyzing the Behaviour of Wind Generated by Tropical Storms and Cyclones

Compute the topographic exposure to wind

Description

The computeTEW() function allows computing topographic exposure to wind (TEW) for each points registred in a data.frame for a tropical cyclone or set of tropical cyclones.

Usage

## S3 method for class 'list'
computeTEW(profiles, points, dtm, angle = 6, threshold = 0, verbose = 2, ...)

Arguments

profiles	list Wind speed and direction profiles from temporalBehaviour() function which must respect the following terminology : 'speed', 'direction' columns in a data.frame
points	data.frame. Consisting of two columns names as "x" (for the longitude) and "y" (for the latitude), providing the coordinates in decimal degrees of the point locations. Same as the "points" argument of the temporalBehaviour() function
dtm	SpatRaster of the elevation data (Digital Terrain Model) for a given location
angle	numeric. Inflection angle of the wind (in degrees). default is 6°.
threshold	numeric. Minimum wind speed threshold (in m/s) requirred to compute exposure. default is 0
verbose	numeric. Whether or not the function should display information about the process and/or outputs. Can be: 2, information about the processes and outputs are displayed (default setting), 1, information about the processes are displayed, 0, no information displayed.
...	additional arguments (not used)

Value

the function returns a list of data.frame with one additional column for topographic exposure to wind (TEW) for each observation or interpolated observation and each Storm.
