| Abstract: | A quantitative diagnosis is carried out for the upward branch of a local meridional circulation over Southern China(SC) during the abnormal snowstorms with severe freezing rain from 10 January to 3 February 2008.The diagnostic study shows that the upward branch is mainly associated with the zonal advection of westerly momentum and meridional temperature advection instead of the latent heating(which is commonly the dominant factor in many storm cases).The corresponding weather analyses indicate that(1) the z... |
