Convection in warm sector of extratropical
The windfield of an extratropical cyclone constricts with distance in relation to surface level pressure, with the lowest pressure being found near the center, and the highest winds typically just on the cold/poleward side of warm fronts, occlusions, and cold fronts, where the pressure gradient force is highest. The area poleward and west of the cold and warm fronts connected to extratropica… WebPatterns of tropical Pacific convection anomalies and associated extratropical wave trains in AMIP5

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.
