Orographic rainfall is when a parcel of air containing water vapor gets to a mountain, it is then forced upwards (the mountain blocking its way).
As the parcel of air is forced upwards, it expands (adiabatic expansion) and also cools. As it cools, it becomes saturated because the amount of water it can hold decreases, so the water vapor begins to condense and finally falls as rain.

Orography is basically the science of mountains. Accordingly, orographic lifting takes place when an air parcel (smaller) or air mass (larger) that contains sufficient water vapor is moved up the windward (upwind) side of a mountain. As the air parcel/mass is lifted, it cools at a relatively constant rate. As the moist air cools, it condenses if lifted far enough (it much reach what's called the dew point temperature), and clouds will form. If the lifting continues, and the tops of the cloud(s) rise high enough - that is, the cloud is thick enough - precipitation size droplets (about 2mm or more) can form.
Rainfall in mountain areas is called: Orographic rainfall.
types of rainfall. orographic is commonly called relief rainfall.
there are 3 types of rainfall which are still exsisting: relief rainfall convectional rainfall Frontal rainfall
orographic, cyclonic/frontal, convectional rainfall
They attract no orographic effect (mountains to raise rain clouds) and any rainfall quickly sinks into limestone.
Rainfall in mountain areas is called: Orographic rainfall.
The correct spelling is orographic rainfall instead of orographic rainfall. When moist air is lifted over a mountain by the wind, the result is orographic rainfall.
types of rainfall. orographic is commonly called relief rainfall.
Orographic
Orographic rainfall occur at d windward side of mountain. It occur by the rising air motion of moist air around the mountain resulting into adiabatic cooling and condensation. While convective rain occur from the nimbostratus part of cloud. "Engr ajimurt001"
there are 3 types of rainfall which are still exsisting: relief rainfall convectional rainfall Frontal rainfall
Relief rainfall occurs when moist air is forced to rise over topographic barriers such as mountains. As the air rises, it cools, condenses, and forms clouds, leading to rainfall on the windward side of the mountain. This phenomenon is common in areas with mountain ranges, such as the western coast of North and South America.
orographic, cyclonic/frontal, convectional rainfall
Because India asked for rain.
The orographic effect occurs when winf from over the ocean passes over a mountain and the lack of rain creates a desert on the other side.
Orographic precipitation is well known on oceanic islands, such as the Hawaiian Islands or New Zealand, where much of the rainfall received on an island is on the windward side, and the leeward side tends to be quite dry, almost desert-like, by comparison.
They attract no orographic effect (mountains to raise rain clouds) and any rainfall quickly sinks into limestone.
