As you have learned from previous lab exercises and the related chapter in the text, air can get saturated with water vapor and then condense water vapor into water droplets, forming clouds and precipitation by decreasing temperature until the dew-point temperature is reached (assuming the amount of water vapor in an area is fixed). In nature, the decrease of temperature is often a result of the increase in elevation. As you have already learned from the related chapter in the text, when air rises its volume expands and cools. Conversely, when air descends, it compresses and warms up. Temperature changes that are caused solely by expansion or compression are called adiabatic temperature changes. Generally speaking, air with a temperature above its dew point (unsaturated air) cools or warms by expansion or compression at a rate of 10°C per 1,000 meters (or 1°C per 100 meters) of changing altitude. This is defined as dry adiabatic lapse rate. After dew point temperature is reached and condensation has occurred, latent heat that has been stored in the water vapor will be released. The release of latent heat slows down the rate of cooling. Thus, as saturated air rises, it continues to cool due to air expansion at a slower rate of 5°C per 1,000 meters (or 0.5°C per 100 meters) of changing altitude. This is defined as wet adiabatic lapse rate.
The figure above illustrates a kilogram of air at sea level with a temperature of 25°C and a dew point of 15°C. This air is forced to rise 5,000 meters over the mountain and descend to a plateau on the opposite side of the mountain (leeward side). Answer the following questions:

21. Notice the seasonal shift in the latitudinal position of the Inter-Tropical Convergence Zone (ITCZ). To where does it shift? Explain the possible cause of the shifting. Describe in detail.
Your Answer:
Surplus heating is the lower latitudes creates an area of relatively low pressure called the Inter tropical Convergence Zone. The ITCZ shifts north and south throughout the year as the sun's energy moves from northern to southern latitude.

Describe in detail.
Your Answer:
The dynamic interaction of warm subtropical air and cold polar air generate area of low pressure in both hemisphere called sub polar lows. These are found pole-ward of the subtropical highs and change latitude and intercity over the course of the year.

Your Answer:
yes I think if the air were to come down it will form a cloud because air gets colder as it rises and AVP max possible water vapor can hold for a specific temperature.When air has max water vapor air reaches state of saturation vapor condense to liquid.
