Question 30

Describe the chief role of the WMO with regard to aviation meteorology :

Answer 30

• Establish and implement together with ICAO, a global regulatory framework for the national meteorology services.

Question 31

Haze, mist fog visibility

Answer 31

Haze = 5000m or less Mist = Between 1000 to 5000m Fog = Less than 1000m

Question 32

AC and AS turbulence and icing when encountering them. (All of these explanations are taken from the WMO).

Answer 32

AC Turbulence = Light to moderate Icing = light ice accretion may occur. AS ``` Turbulence = Turbulence is weak and confined to the lower parts however it may be strong when there is internal convection. Icing = Is generally light ```

Question 33

Indian monsoon where do they blow?

Question 43

According to the Koppen Climate Classification System what is this type of latitude. I had this in my exam back in May and was completely stumped as to what the hell the Koppen Climate Classification System is as the only Koppen I know is a nice refreshing glass of Koppenberg on a summers evening.

Answer 43

Anyway, the answer is along the lines of a “temperate latitude”.
