Coriolis Effect – Why they spin • A deflection of moving objects while earth spins • Counter-clockwise for northern hemisphere, clockwise for southern hemisphere
Typhoon Season May – December = Most Common January – April = Less Common Can occur year round
Hot Spot for Typhoons • 90% of all typhoons form in the Federated States of Micronesia (FSM) • WHY? • Warm, shallow ocean water
What is in a name? • Not named after people • Animals, flowers, astrological signs • Can have multiple names/numbers • Hurricanes that cross over keep original names
Guam - November 27, 1991 • Typhoon Yuri • Winds of 278 km/h = 172 mph • http://www.youtube.com/watch?v=l9vDSWugz08
Fujiwhara Effect • Two cyclonic storms that interact
Good • A Typhoon is a storm system that has what in the center? • High pressure system • Low pressure system • An elevated temperature • Flying debris
Good • A Typhoon forms in what regions of the world? • Along the eastern coast of the United States • Northwest Pacific Ocean • Eastern Atlantic • Along the Canadian border
Good • Typhoons develop over large bodies of warm water and lose their strength if they move over the land.
Good • A strong Typhoon will harbor an area of rising air at the center of circulation.
Bad • If a hurricane crosses over the international date line the name of the typhoon: A. Stays the same B. Changes to a new name C. Keeps both names D. Keeps both names and gets a number E. A and C F. A, B and D G. All of the above
Bad • Typhoons with winds above 170 mph are classified as: • A. Category 1 • B. Category 2 • C. Category 4 • C. Category 5 because this is the highest category that a typhoon can reach, and it can reach category 5 multiple times during the life of the storm.
Bad True or False Typhoons always must happen during April through November if they are going to be category 5.
Bad True or False Typhoons can happen year round, but don’t happen during January because the weather is so cold.
