Map of the number density of best track genesis points, defined as the first point of each track where wind speeds exceed startv , filtered (if desired) to include only those events whose winds speeds exceed some threshold, peakv as set in the params.m file. The track density is in number per year per 1-degree latitude square. The resolution at which the density is calculated and other features of the map can be specified in the params.m file.

The best tracks are filtered the same way as the synthetic tracks are, and gendensity.m must be run before this script can be applied.

This version of the script uses the free m_map routines, which are included with the script set. Various map properties can be set in params.m .
