The Hurricane Database, known as HURDAT2, is the main historical archive of all tropical storms, subtropical storms, and hurricanes in the North Atlantic Basin, which includes the Caribbean Sea and Gulf of Mexico, from 1851 to the present. HURDAT2 is maintained
and updated annually by the National Hurricane Center, as a "by-product" of operations. Today, HURDAT2 is widely used by researchers, operational hurricane forecasters, insurance companies, engineers setting building codes, emergency managers and others.
Thus, its accuracy is essential, but previous work has shown that a reanalysis of HURDAT is necessary because it contains both random errors, systematic biases, and is substantially incomplete. The Atlantic Hurricane Reanalysis Project is an ongoing effort
to correct the errors in HURDAT and to provide as accurate of a database as is possible with utilization of all available data in the context of today's understanding of tropical cyclones.<br>
</div>
<div><br class="ContentPasted3">
</div>
<div class="ContentPasted3">Thus far the reanalysis has added 35 seasons (1851-1885) into the database and has officially revised nearly a century (1886-1970) of additional seasons. These 120 seasons started with only having qualitative historic records along
the coast and from ships at seas (if they successfully returned from an encounter with a hurricane) and progressed to an era of coastal radars, Hurricane Hunter aircraft, and the first generation of weather satellites. The genesis, track, intensity, status,
and decay of each existing tropical cyclone has been reassessed for this period, and previously unrecognized tropical cyclones have been discovered, analyzed, and recommended to the Best Track Change Committee for inclusion into HURDAT. Changes to the number
of tropical storms, hurricanes, major hurricanes, accumulated cyclone energy, and U.S. landfalling hurricanes are documented. An overview of the reanalysis methodology will be provided and results will be put into context of understanding hurricane climate
variability and change. </div>
