Atmospheric fields exhibit extreme variability over a wide range of spatial and temporal scales; they are also intermittent, which means that their activity is often concentrated at smaller and smaller scales. Conventional statistical tools fall short in capturing this and detecting extremes. However, characterization of geophysical fields with their underlying complexities and correlations is ever important in prediction, modelling and understanding the weather conditions we live in, which is even more relevant now in the context of climate change.The heterogeneous properties of atmospheric fields come form the governing non-linear equations of the turbulence (Navier-Stokes), which still remains as an unsolved problem regardless its ubiqui...
