Updating of the Köppen and Thornthwaite and Mather (1955) climate classification system for the Southern Amazonas

The Climate Classification Systems (CCS) play an important role to define the geographic boundaries and agroclimatic zone. Thus, main aim of this paper was determine evaluate Köppen Thornthwaite Matter (1955) climatic classification for Southern mesoregion Amazonas. data have been collected throughout 10 years (April 2008 through April 2018) by National Meteorological Institute (INMET) automatic weather stations installed in municipalities Humaitá, Apuí, Manicoré, Boca do Acre, Lábrea, Amazonas State, Brazil. results shown that Köppen’s CCS has presented same type subtype climate, entire analyzed region. Mather's showed greater sensitivity thermal water climate variation, totaling 4 (four) types 5 (five) subtypes considering information generated respective balances such as deficit surplus, real potential, which can serve a subsidy studies land or arable areas. On other hand, Koppen indicated more general are better suited macroscale. In way, Mather accuracy than method study
