Study of extreme values in weather

This thesis is an attempt to find any sign of global warming by studying weather data on the local level. For this weather data for three cities is analyzed, using statistical methods based on extreme values. Extreme values means that extraordinary situations can be predicted, or in this thesis, quantified. To understand what the analysis of the weather data means, numerous experiments were performed to understand the nature of extreme values. The study of extreme values began with Emil Gumbel in the mid-20th century and is best understood through the application of the Generalized Extreme Value distribution. It is with an applied-math approach that this thesis attempts to understand how local climate changes can be quantified.
