IMPACTS OF SURFACE FRICTION AND OROGRAPHICAL FORCING ON THE EAST ASIA COASTAL CYCLOGENESIS

Some numerical simulations from real data were carried out to examine the impacts of surface friction and orographic forcing on the East Asia coastal cyclogenesis.The results show that the decreasing of the surface friction over the ocean is essential for the cyclone development and the mechanical forcing of Qinghai-Xizang Plateau acts a damping effect in the initial stage of the cyclone.
