深对流系统（DCS）可以迅速地将水汽和其他污染物从对流层低层提升到对流层高层和平流层低层。主要疏散高度决定了空气包裹被提升到的高度。基于CloudSat云廓线雷达2B_GEOPROF数据集和Aura微波临边探测器2级云冰产品，分析了青藏高原及其南坡的主要消散高度。结果表明，青藏高原及其南坡地区的大气环流的主要消散高度（约10-16 km）高于同纬度地区。在青藏高原及其南坡，平均主要消散高度分别为12.9和13.3km。在排除了DCS的影响后，云冰水路径减小了16.8%，云冰水含量增加最大的高度位于178 hPa（约13 km）。青藏高原中东部、南坡西部和东南缘地区的主外流高度和外流水平变幅均大于青藏高原西北部地区。夜间的主要外流高度和外流水平范围比白天低而宽。
Deep convection systems (DCSs) can rapidly lift water vapor and other pollutants from the lower troposphere to the upper troposphere and lower stratosphere. The main detrainment height determines the level to which the air parcel is lifted. We analyzed the main detrainment height over the Tibetan Plateau and its southern slope based on the CloudSat Cloud Profiling Radar 2B_GEOPROF dataset and the Aura Microwave Limb Sounder Level 2 cloud ice product onboard the A-train constellation of Earth-observing satellites. It was found that the DCSs over the Tibetan Plateau and its southern slope have a higher main detrainment height (about 10–16 km) than other regions in the same latitude. The mean main detrainment heights are 12.9 and 13.3 km over the Tibetan Plateau and its southern slope, respectively. The cloud ice water path decreases by 16.8% after excluding the influences of DCSs, and the height with the maximum increase in cloud ice water content is located at 178 hPa (about 13 km). The main detrainment height and outflow horizontal range are higher and larger over the central and eastern Tibetan Plateau, the west of the southern slope, and the southeastern edge of the Tibetan Plateau than that over the northwestern Tibetan Plateau. The main detrainment height and outflow horizontal range are lower and broader at nighttime than during daytime.
