Maps the density of the power dissipation index applied to historical tracks. The power dissipation index is the cube of the storm maximum wind speed integrated over that portion of the track within each lat-long box whose dimensions are specified in params.m. The units are per degree latitude squared. Other map characteristics can be specified in params.m .

The routine pdimap.m should be run before this one.

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 .
