对25.05°S ~ 19.6°N多个测站的ECC臭氧和位温廓线资料进行了处理，以寻找对流层和平流层下部层流结构的类型、季节变化和垂直分布。根据臭氧与位温结构的相关性，确定了与Rossby和重力波诱导的臭氧层有关的臭氧层的比例。平流层中的重力波诱导纹层被发现与冬季的深对流和希洛站夏季的西南风有关，与比勒陀利亚站9月的地形波活动有关。这些站没有发现明显的Rossby波活动。混合特性的低对流层纹层被发现是普遍的希洛，从东北部的运输，大陆热带站在6月至8月期间，这是与生物质燃烧。
ECC ozonesonde ozone and potential temperature profile data for several stations from 25.05°S to 19.6°N were processed to look for the type, seasonal behavior, and vertical distribution of the laminar structure in the troposphere and lower stratosphere. The fractions of ozone laminae associated with Rossby and gravity wave induced laminae were determined from correlations between ozone and potential temperature structure. Gravity‐wave‐induced laminae in the stratosphere were found to be associated with deep convection in the winter months and winds form the southwest in the summer months for the Hilo station, and orographic wave activity for the Pretoria station in September. No significant Rossby wave activity was found for these stations. Lower tropospheric laminae of mixed characteristics were found to be prevalent at the Hilo, related to transport from the northeast, and the continental tropical stations in the June–August period, which are associated with biomass burning.
