Climatology to estimate the various components of the climate and their variability to determine, for example, the wind potential of a given region or global warming. Air quality where they are interested in the phenomena of transport, transformation and dispersion of atmospheric pollutants and may be called upon to design scenarios for the reduction of polluting emissions. Atmospheric convection to refine knowledge of the structure and forces involved in tropical cyclones, thunderstorms and mid-latitude storms; The modeling of the atmosphere and the development of numerical weather prediction.
