Consider the following statements.1. Convectional Rain is common in th...
Convectional rain, or convective precipitation, is a type of rainfall that occurs due to the vertical movement of air masses. It is commonly observed in areas with a hot climate and is associated with the formation of thunderstorms. Let's analyze each statement to determine their correctness:
1. Convectional Rain is common in the summer or in the hotter part of the day.
- This statement is correct. Convectional rain is more likely to occur during the summer season or in the hotter part of the day when the sun's radiation heats the Earth's surface. As the surface temperature rises, the air near the surface also heats up. The warm air becomes less dense and starts to rise, forming what is known as an updraft. As the air rises, it cools down and condenses, leading to the formation of cumulus clouds and eventually rainfall.
2. The area situated on the leeward side of a mountain gets more rainfall in orographic rain.
- This statement is incorrect. Orographic rain is a type of rainfall that occurs when moist air is forced to rise over a mountain range. As the air rises, it cools down and condenses, resulting in rainfall on the windward side of the mountain. The leeward side, on the other hand, experiences a rain shadow effect where the descending air mass becomes drier and inhibits rainfall. Therefore, the area situated on the leeward side of a mountain receives less rainfall in orographic rain.
3. Convectional Rain is very common in equatorial regions and interior parts of continents.
- This statement is correct. Convectional rain is particularly common in equatorial regions and interior parts of continents. In equatorial regions, the intense heating of the Earth's surface throughout the year leads to the rapid formation of cumulus clouds and thunderstorms, resulting in convectional rainfall. Similarly, in the interior parts of continents, where there is limited moisture supply from nearby water bodies, convectional rain becomes a dominant form of rainfall. The absence of significant topographical features such as mountains also allows convective systems to develop more freely in these areas.
Therefore, the correct statements are 1 and 3 only (option C).
