What is the orographic effect for kids?
The orographic effect occurs when air masses are forced to flow over high topography. As air rises over mountains, it cools and water vapor condenses. As a result, it is common for rain to be concentrated on the windward side of mountains, and for rainfall to increase with elevation in the direction of storm tracks.
What is orographic rainfall in simple words?
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 orographic lifting kids?
From Academic Kids Orographic lift occurs when moisture-carrying clouds floating over lower-elevation terrain move over rising terrain. As the clouds are forced to rise in altitude with the air which is carrying them, they cool.
How does the orographic effect affect climate?
The primary factor affecting storm depth, intensity, and local climate is topography. Desert mountains influence rainfall by orographic effects (rapid cooling of rising air masses) which results in increasing rainfall with increasing elevation.
What is an example of the orographic effect?
As an example, the North Shore mountains immediately north of Vancouver often experience heavy rain and snowfall due to orographic uplift. Winds approaching those mountains often do so approximately perpendicular (at right angles) to them, so the mountains form the barrier necessary for this effect.
What do you mean by orographic rainfall Class 9?
Orographic rainfall is also known as relief rainfall occurs when moist air is forced to rise over a mountain range. These winds when they reach the leeward side of the mountains,are devoid of moisture and hence places located on the leeward side of the mountains get scanty rainfall.
Why is rainfall in India orographic in nature?
Orographic rainfall occurs when rain bearing winds strike against the mountains and result in precipitation on the windward side of the mountains. In India, rainfall is orographic in nature as heavy rains occurs on the windward slopes of the Western Ghats and scanty rainfall on the leeward side.
What is a orographic map?
Orography (from the Greek όρος, hill, γραφία, to write) is the study of the topographic relief of mountains, and can more broadly include hills, and any part of a region’s elevated terrain. Orography (also known as oreography, orology or oreology) falls within the broader discipline of geomorphology.
What is meant by orographic lift?
Definition. The process by which a mass of air is lifted by a geographical feature such as a line of hills or a mountain range.
How does the orographic effect create clouds?
Orographic clouds are clouds that develop in response to the forced lifting of air by the earth’s topography (mountains for example). If the air cools to its saturation temperature during this process, the water vapor within condenses and becomes visible as a cloud.
How does the orographic effect affect the weather?
The orographic effect (or orographic lifting) describes the process of air rising as it moves over elevated terrain, like a mountain. The rising air leads to a drop in temperature, which results in condensation, cloud formation, and possible precipitation on the windward side of an elevation.
Where does the precipitation of an orographic cloud come from?
Written By: 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.
Which is the best definition of the word orographic?
Definition of orographic : of or relating to mountains especially : associated with or induced by the presence of mountains orographic rainfall Examples of orographic in a Sentence
Where does most of the orographic rain fall?
Most orographic rain falls upwind of the mountain range, with some also falling a short distance downwind. This process can produce any type of precipitation, including snow, sleet, hail or freezing drizzle. Orographic precipitation, also known as relief precipitation, typically affects mountainous areas near coastlines.
