Variability of horizontal temperature fluxes over the Arctic

We used ERA-Interim reanalysis data to perform a pattern analysis of the tropospheric mean meridional temperature flux in the Northern Hemisphere exploiting an artificial neural network called self organizing map (SOM). The basic explanation of the neural network will be given for a better understan...
