Answers
1) Relief rainfall :
Relief or orographic rain is formed when air is forced to cool when it rises over relief features in the landscape such as hills or mountains. As it rises it cools, condenses and forms rain. The highest rainfall totals of over 1,600 mm per year occur in the mountain areas along the west coast.
2) Formation of clouds :
Clouds are formed when moist air rises upward. As the air rises, it becomes colder. Eventually the air can't hold all of the water vapor in it, and some of the water vapor condenses to form tiny water droplets. When moist air is cooled at the ground, fog is formed in the same way.
Clouds form at a wide range of altitudes, from near the ground to very high in the atmosphere. The appearance of clouds varies a lot, depending on the motions of the air as the clouds are formed.
3) Convectional rainfall :
Convectional rainfall is a type of rainfall that involves the formation of convection currents. This rainfall occurs when the temperature gets high and the warmer air rises up in the atmosphere. On expansion, this air cools down and clouds are formed, which are generally cumulus clouds. These clouds bring rainfall which lasts for a very short duration. Such rainfall is known as convectional rainfall which occurs mainly in the northern hemisphere, predominantly in the tropical regions.
4) Cyclonic Rainfall :
The cyclonic rainfall, on the other hand, is caused due to cyclones. A cyclone has a warm front and a cold front with a substantial difference in the temperatures. A cyclone has a warm front and a cold front with a substantial difference in the temperatures. This difference causes the air above the warm front to rise up and expand. The expansion causes the temperature to drop and condensation occurs, which results in the formation of clouds. These clouds bring heavy rainfall which may even go on for several days. This type of rainfall is known as cyclonic rainfall and generally occurs in the coastal areas of the world.
