例句与用法
- Second , we discuss the influence of environmental referance potential temperture and thermal wind on mesoscale symmetric instability . we find the expression of disturbance stream function and criterion of symmetric instability by analytical method and conclude that change caused by environmental referance potential temperture with height and thermal wind make critical richardson number and disturbance critical half - wave length of symmetric instability larger , that is to say , they benefit the occurance of symmetric instability . third , we study nonlinear perturbation analysis of mesoscale vertical circulation and evolution equation by means of f - plane . non - hydrostatic balance and filiter model
第二，讨论了环境位温与热成风因子对中尺度对称不稳定的影响。运用解析的方法求出了扰动流函数的表达式和对称不稳定的判据，发现环境参考位温随高度的变化与热成风因子使得对称不稳定临界理查逊数及扰动的临界半波长都变大，这有利于对称不稳定的发生。第三，采用f平面、非静力平衡、滤声波模式，讨论了中尺度垂直环流非线性摄动分析及演变方程。
