climate classification

climate classification The grouping of climates into broad types according to their shared characteristics. There are three principal approaches to the task. (a) Generic classification is based on levels of temperature and aridity as these relate to vegetation boundaries. Aridity is usually expressed as ‘effective precipitation’, which is calculated as the ratio of rainfall to temperature. Climatic types are defined by the response of flora to them. The Köppen system, with its modifications, uses this approach. (b) Classifications based on the moisture budget and ‘potential evapotranspiration’ (i.e. the maximum moisture that will be transferred from the ground to the atmosphere, provided that sufficient moisture is available) which do not rely on vegetation boundaries. The Thornthwaite system uses this approach. (c) Genetic (i.e. pertaining to its origin) classification, based on factors related to the atmospheric circulation of major winds and air masses, and on other factors that cause climate, is used in the systems of H. Flohn (1950) and A. N. Strahler.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
