WebExtratropical cyclones and their associated fronts are important weather features for moisture cycling over the Southern Ocean (Wernli and Schwierz, 2006; Simmonds et al., 2012; Papritz et al., 2014). Horizontal temperature advection in the cold and 25 warm sector of extratropical cyclones leads to contrasting properties in the two sectors. WebThe cold sector of a midlatitude storm is characterized by distinctive features such as strong surface heat fluxes, shallow convection, convective precipitation and synoptic subsidence. In order to evaluate the contribution of processes occurring in the cold sector to the mean climate, an appropriate indicator is needed.
