Climate variability

Climate variability

Fluctuating weather conditions in a specific region are defined by a complex process involving certain limiting factors, forcings, natural feedback or iterations between the different subsystems. The analysis of the temporal variations affecting a particular variable implies knowledge of these issues specifically.

At IH Cantabria we combine the knowledge on the geophysics of the system with the application of mathematical techniques. Our studies on climatic variations analyze multiple time scales (seasonal , interannual and secular variability) and have led to the development of mathematical-statistical techniques in the following areas: time series analysis, extreme value analysis, heteroscedastic regression models (to consider changes in the mean and variance), nonstationaryprobability distributions  analysis, characterization synoptic weather types classification techniques and machine learning techniques.

Therefore we investigated: seasonal patterns, teleconnections that can affect a specific variable in a given location, the influence of orbital forcings, or long-term trends.
