baroclinic instability 中文意思是什麼

baroclinic instability 解釋
斜壓不穩定
  • baroclinic : 斜壓
  • 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。
  1. The result indicates that, in the course of the rainstorm in huoshan, there are obvious low - level jet of great intensity, infection of mesoscale shear line, enhancement of plus vorticity which increases intensity of convergence, improves ascending velocity and brings on precipitation, and quick enhancement of helicity which provides the basis to forecast, in addition, convergence of moisture flux and analyzed potential vorticity which reflects baroclinic convective instability sufficiently indicate the characteristics of the rainstorm

    結果表明：此次霍山暴雨發生前後，存在明顯的大強度低空急流，並受到中尺度切變線的影響，而且正渦度的加強引起了輻合加劇，提高了上升速度從而引起降水，同時暴雨發生前螺旋度的迅速增強，也為預報提供了根據，另外水汽通量的輻合以及分析位渦反映出的斜壓對流不穩定都充分體現了這次降水的特點。
  2. One is the change of the basic - state parameters ( e. g., the zonal wind field ) ; the other is existence, in the real atmosphere, of instabilities not described in our model, like for instance, baroclinic instability

    一個是基態參數（例如緯向風場）的變化；另一個在實際大氣存在的不穩定（此模式未予涉及） ，例如斜壓不穩定。
  3. Starting from a two - layer nonlinear quasi - geostrophic baroclinic vorticity equation containing ekman friction, a new generalized energy is proposed to act as lyapunov function and thus a new criterion of nonlinear baroclinic subcritical instability containing two inequalities is obtained

    從含ekman摩擦的二層非線性準地轉斜壓渦度方程出發，提出了一種新的廣義能量作為lyapunov函數，導出了非線性斜壓亞臨界穩定性判據。該判據含有兩個不等式： （ 1 ）
  4. The numerical experiments show that when nondimension parameter 0. 35 < 0. 65, the phenomenon of subcritical instability can exist in two - layer baroclinic atmosphere. the occurrence of subcritical instability is relative to the latitudinal gradient of coriolis parameter

    試驗結果表明：當無量綱量0 . 35 0 . 65時，斜壓兩層大氣中可能發生亞臨界不穩定現象。
  5. First using analytical method, we obtained the nonlinear baroclinic subcritical instability criterion and symmetric subcritical instability criterion. second using numerical experiments, we analyzed the influenced fact on the baroclinic subcritical instability, and we also analyzed what the nonlinear subcritical symmetric instability effects on a rainstorm, and advanced a new mechanism produced the rainstorm

    本文利用解析方法導得了大氣中非線性斜壓亞臨界穩定性判據和對稱亞臨界穩定性判據；並分別用數值試驗方法分析了斜壓亞臨界不穩定的影響因素以及亞臨界對稱不穩定在一場暴雨過程中所起的作用，提出了產生暴雨的新的物理機制。
  6. 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。
