What is the orographic effect simple definition?
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 the definition of orographic in geography?
Definition of orography : a branch of physical geography that deals with mountains.
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 is orographic also known as?
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.
Is orographic a 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 an orographic rain shadow?
When a parcel of warm air reaches a mountain range, it is lifted up the mountain slope, cooling as it rises. This process is known as orographic lifting and the cooling of the air often results in large clouds, precipitation, and even thunderstorms.
What are the characteristics of orographic rainfall?
Orographic Rainfall – Major Characteristics
- When the saturated air mass comes across a mountain, it is forced to rise.
- The rising air expands, eventually, the temperature falls, and the moisture gets condensed.
- The principal characteristic of this type of rain is that the windward slopes get more rainfall.
What is orographic rainfall also known as?
Orographic precipitation, also referred to as relief precipitation, is precipitation produced upon encountering a physiographic upland by a forced upward movement of air (see anabatic wind).
What do you mean by orographic rainfall Class 7?
Orographic rainfall is precipitation produced when the mountains of uplands act as barriers to airflow, forcing the air to rise and the moist air moving upslope coo down by producing clouds and precipitation.
What is orographic storm?
A storm that is produced or significantly enhanced by mountain effects such as orographic lifting or lee cyclogenesis.
What is the orographic rainfall?
What is orographic rainfall explain with certain examples?
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.
How would you describe a desert?
Desert s are areas that receive very little precipitation. People often use the adjectives “hot,” “dry,” and “empty” to describe deserts, but these words do not tell the whole story. Although some deserts are very hot, with daytime temperature s as high as 54°C (130°F), other deserts have cold winters or are cold year-round.
What is meant by orographic precipitation?
Orographic precipitation, rain, snow, or other precipitation produced when moist air is lifted as it moves over a mountain range.
What is the meaning of 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
What is the orographic effect in geography?
The orographic effect is one such case. 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.
