Analysis of climate variables in the Cauca river valley


Biomes are regions of the planet that share similar geological and climatic conditions (Strakhov, 1967), whose interaction initially translates into characteristic soils on which typical vegetation develops. In the sugar cane producing region of the Cauca River Valley, three biomes predominate: the Azonal Orobiome, the Helobiome of the Cauca Valley and the Tropical Alternohygric Zonobiome of the Cauca Valley (Valderrama, 2013). The Azonal Orobiome, which is located in the foothills of the Western mountain range, is characterized by being very dry. The Helobiome of the Cauca Valley, located in the flood zones of the Cauca River (flood plains), is characterized by its dry climate. The Alternohygric Zonobiome, located on the alluvial fans, is also characterized by being dry in the flat area, but is more humid near the Central mountain range. This means that in the Cauca River valley there are different ecosystems, all warm, from very dry areas to humid areas. This chapter deals with the climatic variability of the Cauca River Valley, both spatially and temporally, and seeks to characterize the climate of the region not only based on air temperature and precipitation but with other elements.
