What wind speeds will you experience in the right-front quadrant of a hurricane with sustained winds of 130 mph and a forward motion of 10 mph?
We have learned in class that hurricanes draw their energy from a body of warm water. As a result, studies have shown that once a hurricane passes over a particular location of the ocean, the water temperature is lower than it was before the storm. This indicates that the system has literally pulled or drawn the heat out of the water.
pressure systems, fronts, wind belts

As a tropical (easterly) wave transitions to a tropical storm, the central pressure of the storm system continues to drop (i.e., decrease).
SLOSH is a computer model run by the National Hurricane Center (NHC) that predicts storm surge based on various known storm parameters.
Which hazard does NOT occur in association with a hurricane?
Which region has a year-round hurricane season?
Which ocean basin is typically considered to be the most active for the total number of tropical cyclones/storms reported each year?
The three basic conditions needed for a tropical cyclone to form are: warm water, an unstable parcel of air (i.e. upward lifting of cooling air), and little or no wind shear (i.e., weak upper-level winds).
