On the basis of origin, rainfall may be classified into three main types the Convectional, Orographic or Relief and the Cyclonic of Frontal
1. Convectional rainfall is common in the temperate regions and interior parts of the continents, particularly in the Southern hemisphere.
2. The chief characteristic of orographic rain is that leeward slopes receive greater rainfall
3. In orographic rain, when the unsaturated air comes across a mountain, it is forced to ascend and as it rises it expands temperature falls and moisture is condensed.
Which among the above is /are correct?
Explanation:
1. First statement is incorrect as the convectional rainfall occurs due to the thermal convection currents caused due to the heating of ground due to insolation. The convectional rainfall is prevalent in equatorial regions.
2. Second statement is also incorrect as it should read as The chief characteristic of orographic rain is that leeward slopes receive lesser rainfall than its windward area.
3. Third statement is correct.
