RAMIREZ SANCHEZ, Hermes Ulises; MEULENERT PENA, Ángel Reinaldo  and  GOMEZ REYNA, José Antonio. Update of Bioclimatic Atlas of Jalisco State. Invest. Geog [online]. 2013, n.82, pp.66-92. ISSN 2448-7279.

In this new version of the bioclimatic Atlas of Jalisco State, we present a more detailed description of bioclimate conditions for municipalities in the state, obtained using the most current methodology and larger meteorological database, than used in the previous version, by Amador SEMADES (2009). Processed data were used from 1971-2000 from the Climatological Normal data of the National weather Service belonging to the National Water Commission. The maps were developed using the ArcGIS Geographic Information System 9.3, with monthly and annual seasonality. It is observed that in the months of January to May the predominant bioclimate in most of the state is dry extremes, with lesser occurrence of warm and cold, but from June, the bioclimate changes to warm, with occurrence temperate days. In July temperate bioclimate predominates with lesser occurrence of warm and August is characterized by warm; then from September to October temperate dominates again, followed by warm bioclimate. Finally in November and December extremely dry is dominant again and followed by temperate and cold. As for the annual distribution, since the average bioclimate is a balance of extremes, most of the state has temperate bioclimate.
