The main mechanicm of strengthening barotropic enstrophy is the transformation from baroclinic to barotropic enstrophys. The baroclinic enstrophy comes from the net transport from outside to inside of the blocking area and the net growth of the baroclinic enstrophy. The weakening mechanisms of the barotropic enstrophy are the drag machanism and effect. Therefore, the blocking process is the result of barotropic and baroclinic enstrophy interaction. The transportation of baroclinic vorticity under influence of zonal baroclinic wind has great effect on the maintaining and declining of blocking.And the transportation of baroclinic vorticity with the meridional baroclinic wind is vital in the shaping of blocking.The transportation of barotropic enstrophy under influence of meridional barotropic wind and the transportation of mixing enstrophy under influence of baroclinic wind also have key contribution.Read More
