approximate percentage and the uses of each component. Which com- 

 ponents vary little in their percentage and which are the most variable ? 



6. Explain the direction of the southeast trade winds; also explain why, when

 strong northwest winds. Draw a weather map showing the cyclone 

 and anticyclone responsible for these changes. Indicate position of town 

 by letter T.
