摘要
在对青藏高原大地形的动力和热力作用作物理分析的基础上 ,着重分析了青藏高原大地形的高度、地形坡度和非绝热加热对中高纬低频振荡的影响 ,指出 :青藏高原大地形的高度、合适的地形坡度和地形加热都可以促进低频振荡的形成 ,而且 ,这些因子都会影响低频Rossby波的稳定性 .
WT5BZ]Based on the physical analysis of the dynamic and thermodynamic effects of the Tibetan Plateau, the influence of the height, orographic slope and diabatic heating of the Tibetan Plateau on the low frequency fluctuation at the middle and high latitudes is examined. The results indicate that the height, proper orographic slope and diabatic heating of the Tibetan Plateau can facilitate the generation of the low frequency fluctuation and affect the stability of the low frequency Rossby wave.[WT5BZ] [WT5HZ]
