8. Now consider a situation where you have orographic lifting due to the air mass passing over a mountain range. The ELR is 0.8C/km and the mountain range is 2000 m high. Draw a temperature height diagram showing the movement of an air mass from the bottom to top and then back down again to the same elevation. Assume the air parcel is the same temperature as the atmosphere initially, and is 50% RH. Further assume you reach LCL at 1500 m elevation and remain saturated to the summit. Indicate on your diagram where the air mass is unstable or stable, depending on conditions as necessary. Also show where condensation occurs. (8 marks)

9.For Q.8 above, draw the trajectory of the air mass on the saturation plot below. (3 marks)
