(4 marks) 8.  Ã‚  Ã‚  Ã‚  Ã‚  You are flying at 10,000 feet towards an airport with elevation of 2,127 feet. You ask the FSS operator for the current digit winds at 3, 6 and 9 thousand feet and are told that no wind is available for 3,000 feet. Why is no wind available? 9.  Ã‚  Ã‚  Ã‚  Ã‚  On a ‘Clouds and Weather’ panel of a graphic area forecast cloud layers will be described as to: (a)  Ã‚  Ã‚  Ã‚  Ã‚  amount and the base of the cloud (b)  Ã‚  Ã‚  Ã‚  Ã‚  amount and the top of the cloud (c)  Ã‚  Ã‚  Ã‚  Ã‚  amount and the bases and top of the cloud (d)  Ã‚  Ã‚  Ã‚  Ã‚  none of the above 10.  Ã‚  Ã‚  Ã‚  Ã‚  For an equivalent amount of cooling, more energy is released during condensation at ____________________temperatures. (a)  Ã‚  Ã‚  Ã‚  Ã‚  colder (b)  Ã‚  Ã‚  Ã‚  Ã‚  warmer (c)  Ã‚  Ã‚  Ã‚  Ã‚  they will be the same (d)  Ã‚  Ã‚  Ã‚  Ã‚  energy will be absorbed, not released 11.  Ã‚  Ã‚  Ã‚  Ã‚  The three principle properties of the atmosphere are: (a)  Ã‚  Ã‚  Ã‚  Ã‚  rain, snow, hail (b)  Ã‚  Ã‚  Ã‚  Ã‚  heat, cold, moisture (c)  Ã‚  Ã‚  Ã‚  Ã‚  expansion, compression, mobility (d)  Ã‚  Ã‚  Ã‚  Ã‚  pressure, temperature, wind 12.  Ã‚  Ã‚  Ã‚  Ã‚  Atmospheric processes which effect the weather are, for the most part, restricted to the: (a)  Ã‚  Ã‚  Ã‚  Ã‚  thermosphere (b)  Ã‚  Ã‚  Ã‚  Ã‚  mesosphere (c)  Ã‚  Ã‚  Ã‚  Ã‚  stratosphere (d)  Ã‚  Ã‚  Ã‚  Ã‚  troposphere 13.  Ã‚  Ã‚  Ã‚  Ã‚  The temperature in the lowest part of the stratosphere_______________with altitude. (a)  Ã‚  Ã‚  Ã‚  Ã‚  increases (b)  Ã‚  Ã‚  Ã‚  Ã‚  nearly constant (c)  Ã‚  Ã‚  Ã‚  Ã‚  decreases slowly (d)  Ã‚  Ã‚  Ã‚  Ã‚  decreases rapidly 14.  Ã‚  Ã‚  Ã‚  Ã‚  Why when using a graphic area forecast is it important to be aware of the elevation of the local topography?
