10-38. Which of the following is a well-known 



sign that appears in the open sea far in 

 advance of an approaching tropical 

 cyclone?

 long swell waves with a period of 



1. 9 to 15 seconds 



2. 9 to 12 seconds 



3. 10 to 20 seconds 



4. 12 to 15 seconds 



10-40. Unless a tropical cyclone is unusually 

 well-developed, the 200-mb level is 

 marked by 



1. cyclonic inflow 



2. anticyclonic inflow 



3. cyclonic outflow 



4. anticyclonic outflow 



In items 10-41 through 10-45, select from 

 column B the dates of highest frequency of 

 tropical cyclone formation in the areas in 

 column A. 



10-46. The most dominant meteorological element 

 controlling the type and intensity of 

 weather is 



1. wind 



2. pressure 



3. water vapor 



4. temperature

 or solid precipitation and water 

 particles?

 forms of precipitation except 



1. dew 



2 . snow 



3. sleet 



4. drizzle 



10-49. Sometimes referred to as mist, very 



small and uniformly dispersed droplets 

 that appear to float in the air defines 

 which of the following phenomena? 



1. Drizzle 



2. Rain 



3. Dew

associated with thunderstorm activity? 



1. Ice pellets 



2. Hail 



3. Snow 



4. Snow grains 



10-52. The primary difference between drifting 

 snow and blowing snow is 



1. a ten knot difference in the wind 

 speed 



2. the height above ground that the 

 particles are lifted 



3. the visibility with blowing snow is 

 greater 



4. the size of the particles that are 

 moved by the wind
