Title

DEVELOPING A THERMODYNAMIC MODEL TO PREDICT MINIMUM TEMPERATURE DUE TO COLD AIR ACCUMULATION OVER A COMPLEX TERRAIN (A CASE STUDY: NORTH MOUNTAINS OF TEHRAN)

Pages

  165-174

Abstract

 Topography is the most important parameter which produces MINIMUM TEMPERATUREs in COMPLEX TERRAIN. Radiative inversion occurs in the mountains and produces radiative freezing. When the land surface is cooled, a boundary layer forms. Since cold air is heavier than warm air, therefore, it flows toward the down slope, which is named KATABOLIC FLOW. When KATABOLIC FLOWs are formed, cold air accumulates in the valleys and thereafter in places which do not have a good drainage of air. Based on thermodynamic equations a model was developed to consider the accumulation of cold air in each point of a COMPLEX TERRAIN. MINIMUM TEMPERATURE prediction model (MTPM) was developed and used to predict the MINIMUM TEMPERATURE in COMPLEX TERRAINs. This thermodynamic model uses digital elevation model to produce MINIMUM TEMPERATURE maps. Running MTPM for North Mountains of Tehran showed a good correlation between modeled and actual MINIMUM TEMPERATUREs.
