Abstract
Analysis of the meteorology of Polar Regions is fundamental to the process of
understanding the global climatology of the Earth and Earth-like planets. The
nature of air circulation in a polar vortex is of preliminary importance. I
have show that the local and continental spatiotemporal relationship between
near surface wind events is self-organized criticality. In particular, the wind
event size, wind event duration, and duration of quiescent wind event are well
approximated by power-law distributions. On a continental scale, the wind
events in the Antarctic tend to be self-organized criticality with ergodic
properties. A similar self-organized criticality wind event was also found in
Taylor Valley located at McMurdo Dry Valleys discovered by Captain Scott's
expedition. Captain Scott's meteorological Terra Nova record was also examined.
I have also revisited and re-analyzed wind events in Hornsund at Spitsbergen
Island, in terms of marginal probabilities and marginal copulas which describe
positive L\'evy process.
