barotropic instability 中文意思是什麼
barotropic instability
解釋
正壓不穩定- barotropic : 正壓的
- instability : n. 動搖性，不穩定性；不堅決，反復無常，三心二意。 the instability of human affairs 人事滄桑。
-
One of factors which activize the explosive development of cyclone exists strong convective instability in lower layers from the analysis of the barotropic potential vorticity
由正壓位渦分析得出，氣旋爆發性發展的啟動因子之一為低層存在強對流性不穩定。 -
In a word, convective instability strong baxoclinicity barotropic advection of potential vorticity and latent heat release are factors which activize this explosive development of cyclone
總之，對流不穩定、強斜壓性和正壓位渦平流、潛熱釋放是本次氣旋發展的啟動因子。 -
Inertial instability barotropic advection of potential vorticity the subsidence of the large value of potential vorticity above cyclone and geostrophic adjustment process is dynamical factors which make the cyclone developed violently
慣性不穩定，正壓位渦平流以及正壓位渦大值下沉至氣旋上空和地轉適應過程是氣旋強烈發展的動力因子。 -
Internal waves are a kind of bridge relating the diapycnal mechanical mixing to external sources of mechanical energy : first, internal waves are driven by wind stress and barotropic tide so that large amount of mechanical energy are transported to abyssal ocean with propagation of internal waves ; second, the mechanical energy can directly be cascaded to mixing through instability and breaking of internal waves
內波是外界提供的機械能與混合之間聯系的橋梁之一，一方面風和潮汐通過激發內波，將能量向深海和大洋內區傳遞，另一方面，內波的不穩定和破碎直接將機械能串級到小尺度湍流混合中去。開展傾斜地形上內波的傳播以及內潮的產生等方面的研究對海洋混合過程的參數化以及混合對大洋環流的影響等方面的研究具有重要的科學意義。 -
The result also shows, for the waves of 0. 5 k < 6, the nonlinear baroclinic subcritical instability easily occurs than the barotropic one. 2. a two - layer quasi - geostrophic model forced by surface friction and radiative relaxation is used to study numerically the phenomenon of subcritical instability in baroclinic atmosphere
文中還指出對於0 . 5 k 6的中等波長的波動，非線性斜壓亞臨界不穩定比正壓亞臨界不穩定更易發生，這與實際大氣中的情況類似。
