Cyclones Disturbance Layer

Cyclones Disturbance Layer

Usage

disturbance_cyc(spatial_grid, spde, config_sp)

Arguments

spatial_grid

An sfc_POINT object representing the full spatial grid.

spde

A list containing the SPDE mesh, SPDE object, precision matrix Q, and projection matrix A.

config_sp

A list with:

• years – vector of years to simulate

• seed – random seed

Value

A list with:

• cyc_effects – matrix of spatial random field values

• cyc_effects_df – long-format data frame with Longitude, Latitude, Year, and Value

• cyc_pts_sample – cyclone effects projected onto the spatial grid

• cyc_pts_effects – long-format data frame suitable for plotting

Details

Generates a synthetic cyclone disturbance layer by combining a temporal trend with a spatial random field projected onto a spatial grid.
