What is the process of orographic rainfall?

orographic precipitation, rain, snow, or other precipitation produced when moist air is lifted as it moves over a mountain range. As the air rises and cools, orographic clouds form and serve as the source of the precipitation, most of which falls upwind of the mountain ridge.

What is the process of convectional rainfall?

Convectional rainfall When the land warms up, it heats the air above it. This causes the air to expand and rise. As the air rises it cools and condenses. If this process continues then rain will fall.

What is Convectional rainfall and orographic rainfall?

Convectional rainfall. When the land warms up, it heats the air above it. This causes the air to expand and rise. Orographic precipitation, rain, snow, or other precipitation produced when moist air is lifted as it moves over a mountain range.

What is torrential rainfall?

If it’s raining extremely hard, then the rain is torrential — it’s absolutely pouring. Use torrential to describe something that’s happening in torrents, or turbulent flowing streams. When there’s a torrential storm, there’s so much rain falling so fast that you’ll be soaked in about three seconds.

What are convective showers?

Episodes of convective precipitation falling in an area no more than about 10 km wide and for a time period of less than about one-half hour.

What is orographic rainfall class 7th?

Orographic rainfall occurs when a mass of air is pushed up because of a structure with very high elevation, such as a mountain. The lifted air cools down and precipitation occurs. Rain shadow area is formed on the other side of the elevation.

What is orographic rainfall Upsc?

Orographic Rainfall As the moisture laden air gains height, condensation sets in, and soon saturation is reached. The surplus moisture falls down as orographic precipitation along the windward slopes. The chief characteristic of this sort of rain is that the windward slopes receive greater rainfall.

What is torrential rain?

What causes torrential rain?

The factors that cause torrential rain are similar to those that cause regular rain. As with any rain storm, the necessary conditions are moisture and atmospheric instability [10]. Because moisture is a necessary ingredient for rainfall, a warm air mass can lead to longer, heavier rains than a cool one [4].
