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，討論了環(huán)境位溫與熱成風(fēng)因子對(duì)中尺度對(duì)稱不穩(wěn)定的影響。運(yùn)用解析的方法求出了擾動(dòng)流函數(shù)的表達(dá)式和對(duì)稱不穩(wěn)定的判據(jù)，發(fā)現(xiàn)環(huán)境參考位溫隨高度的變化與熱成風(fēng)因子使得對(duì)稱不穩(wěn)定臨界理查遜數(shù)及擾動(dòng)的臨界半波長(zhǎng)都變大，這有利于對(duì)稱不穩(wěn)定的發(fā)生。第三，采用f平面、非靜力平衡、濾聲波模式，討論了中尺度垂直環(huán)流非線性攝動(dòng)分析及演變方程。
