re research on line, landfall has nothing to do with hurricane
classification.
Typical info below.
*Here's how a hurricane works*: A tropical storm begins to brew over the
ocean. As it makes contact with warm ocean waters — if the temperature
of the water is above 26.5 degrees Celcius (80 Fahrenheit) — the storm's
heat and energy intensify. Winds rotate counterclockwise around a calm
center (the "eye"). When the sustained speed of the winds reaches 74 mi
(119 km) per hour, the storm is officially classified as a hurricane.
(The term applies to storms which occur over the N Atlantic Ocean, the
NE Pacific Ocean east of the dateline, or the S Pacific Ocean. The same
storm occurring over the NW Pacific Ocean west of the dateline is called
a typhoon <http://www.answers.com/topic/typhoon>; one occurring over
Australia and the Indian Ocean is a tropical cyclone
<http://www.answers.com/topic/tropical-cyclone>, but the winds rotate
clockwise.)
