Mathematical modelling European temperature data: spatial differences in global warming
share
This paper shows an analysis of the gridded European precipitation data. We combine simple linear regression with data mining tools like clustering, and evaluate the strength of the results by the modern bootstrap methods. We have used the 0.5 grade-grid of daily temperatures for 65 years, created by the European Climate Assessment. We have checked the stability of the results by changing the starting point of the linear regression - this approach might be valuable for climatologists in finding the "best" starting point for assessing the global warming in Europe. Different bootstrap approaches were compared and it turned out that the dependent weighted bootstrap is the best for checking the significance of the estimators.
