Description
Summary:The differents characteristics of ground covering in the Rio de Janeiro Metropolitan Region, where regions with high percentage of asphalt and concrete are surrounded for rural areas, determine the appearance of a temperature horizontal gradient knowledge as urban heat island phenomenon. Besides, diverse scientific works have demonstrated the influence of the mesoescale atmospheric circulation and synoptic scale in the urban heat island formation and dissipation. The main subjetive of study consists in analyze from simulated results, with the mesoescale model MM5, and observacionals data, the influence of synoptic systems and locals characteristics of the RMRJ in the formation and dissipation of urban heat island.
