Modeling Functions

Description

hurrecon_model_site calculates wind speed (meters/second), gust speed (meters/second), wind direction (degrees), and enhanced Fujita scale wind damage for a given hurricane and site. If width is TRUE, the radius of maximum wind (rmw) and scaling parameter (s_par) for this hurricane are used; otherwise values for ALL are used. If save is TRUE, results are saved to a CSV file on the site subdirectory.

hurrecon_model_site_all creates a table of peak values for all hurricanes for a given site. If width is TRUE, the radius of maximum wind (rmw) and scaling parameter (s_par) specified for each hurricane is used; otherwise values for ALL are used. If save is TRUE, results are saved to a CSV file on the site-all subdirectory.

hurrecon_model_region calculates peak wind speed (meters/second), peak enhanced Fujita scale, peak wind direction (degrees), peak cardinal wind direction, and duration of EF0, EF1, EF2, EF3, EF4, and EF5 winds (minutes) for a given hurricane over a region. If width is TRUE, the radius of maximum wind (rmw) and scaling parameter (s_par) specified for each hurricane is used; otherwise values for ALL are used. If time_step is NULL, the time step is calculated. If water is FALSE, results are calculated for land areas only. If save is TRUE, results are saved as a GeoTiff file on the region subdirectory.

hurrecon_model_region_dt calculates wind speed (meters/second), enhanced Fujita scale, wind direction (degrees), and cardinal wind direction for a given hurricane over a region at a specified datetime. If width is TRUE, the radius of maximum wind (rmw) and scaling parameter (s_par) specified for the hurricane are used; otherwise values for ALL are used. If water is FALSE, results are calculated for land areas only. If save is TRUE, results are saved as a GeoTiff file on the region-dt subdirectory.

hurrecon_model_region_all runs hurrecon_model_region for each hurricane and calculates the maximum Fujita value and the number of hurricanes for each Fujita value (EF0-EF5) across a region. If width is TRUE, the radius of maximum wind (rmw) and scaling parameter (s_par) specified for each hurricane is used; otherwise values for ALL are used. If time_step is NULL, the time step is calculated. If water is FALSE, results are calculated for land areas only. If save is TRUE, intermediate results for each hurricane are saved as GeoTiff files on the region-all subdirectory, along with summary results for all hurricanes (summary.csv, summary.tif). If save is FALSE, intermediate results are saved to the R session temporary directory.
