CASTRO MENDEZ, Carlos Enrique; AGUALIMPIA DUALIBY, Yolima del Carmen  and  SANCHEZ SANCHEZ, Fernando. Climate Model of the Moorlands of the Colombian Eastern Mountain Range Applied to Soil Temperature Regimes. Perspectiva Geográfica [online]. 2016, vol.21, n.1, pp.33-62. ISSN 0123-3769.

The application (with consistent criteria) of soil temperature regimes has not been necessary and decisive so far, because this descriptive information was considered sufficient. The temperature assigned to the ground came from direct reclassification of the edaphic environmental climate with average annual values given to each altitudinal strip more than 200 years ago, which today is not consistent with the changes, have been perceived through biophysical geography. A climate model, based on isotherms, is proposed to determine soil temperature regimes from information under vegetation cover and soil for each particular mountain slope. Temperature gradients (°C/100 m) of 0.73 and 0.61 were found in the western and eastern slopes, respectively, of the Colombian Eastern Mountain Range Moorlands. Soil temperature was 1.9 °C higher than air temperature, and soil temperature regimes were defined as cryic, isofrigid and isomesic.

Keywords : isotherms soil; temperature regime; climate model.
