 Tropical Storms and Hurricanes Quantitative Exercises

 1 . Examine the Atlantic hurricane information to determine the strongest hurricane of the season and the strength of its winds. 2 . Examine the Atlantic hurricane information and select the best explanation for the track of Hurricane Georges that contributed to its extreme strength. 3 . Compared to Atlantic hurricanes, hurricanes that form in the east Pacific rarely affect the United States. The reason for this is _______. 4 . Compare the Satellite Photo of Hurricane Bonnie with the Radar Image of Hurricane Bonnie as the storm made landfall along the east coast of the United States. What feature of the hurricane can the radar image show that isn't captured well by the satellite photo? 5 . Examine the direction of hurricane movement and estimate the net wind speed on the right-hand side of a 200 km/hr hurricane moving northward at 50 km/hr. 6 . Examine the direction of hurricane movement and estimate the net wind speed on the left-hand side of a 200 km/hr hurricane moving northward at 50 km/hr. 7 . Suppose at 6:00 am a hurricane is 400 km due east of Miami and moving due west at 10 km/hr. A hurricane watch should be issued at _____. 8 . Suppose at 6:00 am a hurricane is 400 km due east of Miami and moving due west at 10 km/hr. A hurricane warning should be issued at _____. 9 . One degree of latitude represents approximately 111 km on a hurricane tracking chart. Suppose a hurricane is located at 25° N and moving due north at 30 km/hr. Its latitude in 6 hours will be ______. 10 . Hurricanes don't form at latitudes less than 5o from the equator because there the Earth's planetary vorticity (f) is too weak to impart sufficient spinning motion. Given f = 2 x omega x sin (latitude)where omega = angular velocity of Earth = 7.29 x 10-5 sec-1, what is the minimum planetary vorticity (sec-1) needed to spawn a hurricane? Answer choices in this exercise are randomized and will appear in a different order each time the page is loaded.
