Question

| 162% Answer the following questions after completing the problems in Part I. You will also need to refer to the chart of Saturation Mixing Ratios in Figure 15-l; interpolate from the chart as needed. Assume that condensation begins at 100% relative humidity and that no evaporation takes place as the parcel descends. 5. On the windward side of the mountain, should the relative humidity of the parcel change as it rises from 2000 m to 4000 m? (a) (b) Why? 6. As the air rises up the windward side of the mountain, What is the capacity (saturation mixing ratio) of the rising air at 2000 meters? (a) (b) What is the capacity of the air at 4000 meters? g/kg What is the capacity of the air after it has descended back down to sea level on the lee side of the mountain? 7. Assuming that no water vapor is added as the parcel descends down the lee side of the mountain to sea level, is the water vapor content (the mixing ratio) of the parcel higher or lower than before it began to rise over the mountain? 8. (a) (b) Why? F12 F10

Explanation / Answer

the capacity of the air at 4000 ft will be 5.76 and more As the air rises up the windward side of the mountain, is the capacity (saturation mixing ratio) of the rising air at 2000 meter
