What does orography mean?
Orography is a specialized branch of physical geography concerned with the elevation, form, and relief of land, especially mountainous and hilly terrain. The term is formal and is used in geography, geology, climatology, and meteorology, where the distribution and character of raised land can strongly affect climate. For example, a mountain range may intercept moist air, causing heavy precipitation on its windward side and creating a comparatively dry rain shadow on the leeward side. Orography also gives maps and analyses of terrain a more specific focus than the broader study of topography, which includes the position and arrangement of natural and built features. Although “orographies” is grammatically possible, the word is normally used in the singular as a field of study or an uncountable name for the configuration of relief. The concept is useful whenever terrain, rather than place alone, is central to explaining an environmental pattern.

Where does orography come from?
The term developed in English during the 19th century from Greek ὄρος (oros), meaning “mountain,” combined with the combining form -graphy, derived from Greek -graphia, meaning “writing” or “description.” The two elements together denote the description or study of mountainous relief. Its relatives in other European languages were formed from the same Greek roots.
