NOAA's Office for Coastal Management maintains a detailed online interactive mapping tool called Historical Hurricane Tracks at www.coast.noaa.gov/hurricanes. This tool offers users the ability to search and display global tropical cyclone data. The information can also be downloaded in widely-used GIS data formats.
Satellites, reconnaissance aircraft, Ships, buoys, radar, and other land-based platforms are important tools used in hurricane tracking and prediction. While a tropical cyclone is over the open ocean, remote measurements of the storm's intensity and track are made primarily via satellites.

My preferred way to divide complex numbers is to multiply numerator and denominator by the complex conjugate of the denominator
