辐合带 meaning in English

belt of convergence
belt of convergency

Results of experiment b demonstrate that a convergence zone of wind vector and water vapour with dense pressure gradient is formed alone the coast after tc ' s outer circulation encountering land , which results in more precipitation
试验b的结果显示，热带气旋外圈环流与陆地接触后到中心登陆前后，沿海岸线一直存在一条气压梯度相对密集的风矢量、水汽辐合带，引起该处降水增多。
The occurrence of cirrocumulus clouds indicates the distant presence of a convergent zone such as a pressure tough or a cyclone in lower levels ; or a frontal zone where cold air meets moist warm air . vigorous convection and lifting motion bring water vapour up in the sky where the water vapour sublimes into ice crystals , forming the high clouds
卷积云的出现显示远处地方低层有一强辐合带如低压槽或气旋或锋面即暖湿空气碰到冷气团，向上爬升的交界面形成，强烈的对流和抬升运动将水汽带到高空，在那里水汽直接升华变为冰晶而形成高层云。
