Cálculo de índices de cambio climático en base a datos diarios de temperatura y precipitación para la región costa en el sur del Ecuador

Abstract

Abstract: Climate change is evident across the planet. However, there are regional and local differences that must be evaluated to implement adequate mitigation and adaptation strategies to the climate of the future. Regional studies regarding climate change in Ecuador so far are scarce, due to the lack of historical meteorological information. The present study analyzed the trends of 12 climatic indices for three coastal provinces of Ecuador during the period 1980 and 2015. The basis of the analysis is the daily information on temperature and precipitation from 27 meteorological stations obtained from the National Institute of Meteorology and Hydrology (INAMHI). To calculate the trends of the different climatic indices, the software RClimDex 1.0 was used, which allows evaluating climate change in the region. The results showed non-uniform trends in the study area, due to local circumstances and the prevailing atmospheric conditions. Furthermore, the trends were mostly not statistically significant due to limited information. However, the changes with respect to the temperature indices could be related to changes in cloudiness, which also caused variation in precipitation.
