favorable event
2.The results show that a warm high ridge at the middle level and transformed surface cold high over the plain provide a good background condition; a cooling process produced by net surface radiation fluxes is the trigger and strengthening mechanism for the fog event; the subsidence flow at the middle and low tropospheric levels is favorable for the setting-up and maintenance of stable stratification at the boundary layer and weak wind condition at the ground layer over the fog region; the transportation of weak warm advection at lower levels and weak lift motion at the boundary layer play a very important role to the long maintenance of the fog event; the intrusion of north wind accompanied by cold advection is a main dynamic factor of the fog dissipation.
3.The chief representative Bak Man Ky of Korean Daejeon Municipal Government especially touched upon the historic meaning of this Asia Outdoor Trade Fair which will be held in Nanjing, he said it ought to be a major event that worth of the concern of all outdoor products industries in Asia and will provide a favorable way for a number of brands come into China and also go out into international stage.
4.By mesoanalysis of a precipitation that occurred in the middle reaches of the Changjiang River, 8th Jul. in 2003, the formation and development of the event, its relation with the meso-microscale system are studied, it is emphasized that the low-level jet would cause favorable thermodynamic, moisture and dynamic conditions for the heavy rainfall in the middle reaches of the Changjiang River and that the mesoscale vortex formed in the left of the low-level jet would stimulate strong convective clouds and cause the heavy rain.
