The aim of this TFC is investigate and analyse the influence of the climate change in the formation of thermal winds in the Mediterranean coast of the Iberian Peninsula, in special attention in sea and land breeze, using three different numerical models. The sea breeze is formed in this coastline of Iberian Peninsula from Mars to September, and has the maximum intensity in early spring and latest summer and early autumn, when the thermal gradient between the airs placed inland and over the sea is large. In addition, this TFC propose to answer several questions, like if the global warming in the Mediterranean area will increase or decrease the thermal gradient, and so the intensity and frequency of the sea and land breeze could be modified, or if the month to begin and to finish could be displaced in time. The structure of TFC is as follow: 1. A Bibliographic Research about thermals wind formation, and mathematical interpretations. 2. A training about the numerical models of climate change, overall the regionalization models integrated in Prudence and Ensembles Projects, both financed by the UE. 3. A selection of those areas in the Mediterranean coast of the Iberian Peninsula with large sea and land breeze, and data gathering and analyse of the simulation in these areas. 3. A process and interpretation of the results, and main conclusions. 4. Write the memory.
