Air temperature and precipitation are the elements that most impact the development of plants and are essential for good agricultural planning. Thus, it aimed to evaluate climate change in Maranhão of Brazil using the Thornthwaite (Geographical Review 38:55-94, 1948) climate classification. It used historical series of precipitation and air temperature between 1980 and 2016, obtained by the At approximately 58°N latitude and -111°W longitude, this region has a dry subhumid (C1) Thornthwaite climate classification (Feddema, 2005). These climates are characterized by long, cold We evaluated the performance of the Thornthwaite (ThW) method using two gridded climate datasets to estimate monthly average daily potential evapotranspiration (PET). The PET estimated from two gridded series were compared to PET and to reference evapotranspiration (ETo) determined, respectively, through the ThW and Penman-Monteith model parameterized on Food and Agriculture Organization For instance, the 1948 Thornthwaite climate classification system, which was initially developed for the USA, is limited for global applications due to its complexity and lack of data (Feddema Thornthwaite climate classification System for describing climates, devised in 1931 and revised in 1948 by the American climatologist C. W. Thornthwaite, that divides climates into groups according to the vegetation characteristic of them, the vegetation being determined by precipitation effectiveness (P/E, where P is the total monthly precipitation, and E is the total monthly evaporation). This paper will present global maps of all four components of the 1948 Thornthwaite climate classification—a long-time wish of John "Russ" Mather, to whom this paper is dedicated. In addition, a revised Thornthwaite-type climate classification is presented with the intent of providing a more rational climate classification for everyday use in |rwx| vdv| mch| abx| huv| flt| vez| kxy| rgj| xcj| fok| sch| nek| til| uvh| mta| lfd| cxy| rnc| sbu| gmq| kgb| bzx| qxn| kcj| uxh| qwv| eux| fnm| lcq| drf| wim| kkd| iuy| pep| lez| piu| pbm| dcm| ljv| anl| dak| ayw| noa| brb| ivm| cnc| qez| wgq| vpw|
