Modelización en Geografía Física.-Evolución espacio-temporal de variables climáticas en la Cuenca del Río Segura en el periodo 1976-2007

Abstract

ABSTRACT This work developes a methodology to analyse the spatio-temporal distribution of the must important climatic variables controlling environmental and socioeconomic processes in river Segura basin.

A global multiple regression model is applied to interpolate climatic variables. Using as independent variables distance to sea, height aspect, easting and northing. In cases where it is not possible to use a global model, local interpolation procedure will be used (krigging, IDW or splines).

The methodology has six stages: 1) selection of stations, 2) data filtering and gep filling after an homogeinity test, 3) estimation of parameters for a regression model, 4) interpolation, 5) validation and 6) evolution analysis.
