摘要
对中、美、澳三国AMEX试验期间“向阳红5号”定点观测到的气象和海洋资料分析得出:①台风形成前,大气整个中、低层空气湿度较大,台风一旦形成,大气湿度最大层主要集中在中空;②风速垂直切变小,对形成台风是一个必要条件,但并非整个对流层风速切变都小,而且不同地区形成的台风,风速切变状况是不同的;③厄尔尼诺年南半球与北半球对应位置同期的θ_G、θ_8、Q_b相差不大,但是南半球的θ_c较北半球的大。
The analyses of the meterological and oceanographical data from seriel observations aboard R/V Xiangyanghong 5 during the voyage of joint AMEX experiment by Australia,China and the United States show that (1) there is high level of humidity within middle and low layers of troposphere at the initial stage of a typhoon's formation,and once a typhoon has fully developed,the highest level of humidity remains within middle layer of tropisphere;(2) although small vertical wind shear is a requisition for a typhoon's growth,it is not always the case for the whole troposphere but.varies with regions and (3) in El-Nino years,the contrast of values of QE,Qs and Qb of the region is small to those of the corresponding zones in the northern hemisphere while the value of Qc of the region is greater than that of the zones in the northern hemisphere.
