Name Section EXERCISE 22 PROBLEMS-PART II-INTERNET The following questions are based on satellite movie loops available on the Hess Physica raphy Laboratory Manual, 12th edition, website at www.MasteringGeography.com, the Exercise 22, or by scanning the QR (Quick Response) code for this exercise. Click on Figure 2 Hurricane Katrina Movie Loop." to see an infrared satellite movie loop of Hurricane from August 24 to August 30, 2005, as it moves across Florida into the Gulf of Mexico and finally y.com, then select mes onshore near New Orleans. You may also want to view Figure 22-6, a close-up mo movie loop co of Hurricane Katrina on August 29. After viewing the satellite movie loops several tit the following questions: Assuming that a well-defined eye and a tightly circular shape are indications of a strong hurricane, what generally happens to the strength of Hurricane Katrina be- tween August 24 and August 28? 1. (a) (b) What can explain this change in strength? What is the general direction of movement of Hurricane Katrina on August 24 (at the beginning of the movie loop)? 2. (a) To the What is the general direction of movement of Hurricane Katrina on August 30 (at the end of the movie loop)? (b) To the (o) What may explain this change in direction? 3. Look at Hurricane Katrina on August 29 (the Figure 22-6 movie loop witt be especiall of cloud movement is converging counter- helpful here). Although the f che clouds (such as those you see just to the west of Florida) clockwise, notice that some of the clouds (such as those are diverging clockwise. What explains these diverging clouds? overall pattern of cloud move 142 onright 2017 Pearson Edacation, IncExplanation / Answer
2. a. Hurricane Katrina began as a tropical depression near the Bahamanas on August 23. After that it strengthened into tropical storm and was named as tropical storm after it made a landfall near the southern tip of Florida. So the general direction of Katrina is towards west.
b. After passing through warm water of Gulf of Mexico, the hurricane intensify and made its landfall near Louisiana, Mississippi, Katrina move towards north to the Central United States and finally dissippiated near the Great Lakes on August 31 and was absorbed by a cold front. The general direction of Katrina on August 31 is towards north east.
c. When the Katrina pass over the warm waters of the Gulf of Mexico it intensify rapidly and changed its direction. The low wind shear, warm sea surface temperatures and good upper level outflow was the factor due to which Katrina changed its direction abruptly.
3. The diverging clouds to the west of Florida indicates the calm weather conditions. This can be the eye of the cyclone which is the most calm part of a hurricane.
