Meteorology practice test

Pass mark 75% from twenty randomly chosen questions.


#1. Fog that forms from the interaction of two airmasses is called:

#2. For saturated air, the lapse rate is _______________ ; this is called the Saturated Adiabatic Lapse Rate (SALR)

#3. A cold front moves ________ a warm front.

#4. For smog to form:

#5. If flying on a hazy afternoon in Britain, in which direction will visibility be greatest?

#6. The lapse rate for a dry parcel of air is:

#7. At the passage of a warm front you would expect:

#8. Carburettor ice is formed

#9. The atmosphere:

#10. In the ISA, what is the atmospheric pressure at sea level?

#11. In the northern hemisphere, compared to the surface, the 2000 foot wind can be expected to:

#12. Following the passage of a typical cold front, an observer at the surface would expect to experience which of the following conditions:

#13. Mean sea level density in the International Standard Atmosphere (ISA) is:

#14. You’re at an airfield just a few feet above sea level, and it’s a standard day (ISA). Approximately what altitude would you find a temperature of -1 degrees Celsius?

The standard lapse rate is 2 degrees for every thousand feet. ISA standard temperature is 15 degrees at sea level.

The difference between 15 and -1 is 16 degrees. Dividing this value by 2 (two degrees per thousand feet) gives you 8. Multiply that by 1,000 and you get an altitude of 8,000 feet.

#15. The Geostrophic Wind flows:

#16. Virga means:

#17. The atmospheric situation where temperature increases with height is called a(n):

#18. The decode for hail in a METAR is:

#19. Orographically formed clouds occur:

#20. Considering the following METAR for Catania-Fontanarossa airport: LICC 231020Z 23007KT 200V280 9999 FEW060 13/04 Q1028=. Which of the following statements is not incorrect?
