虽然对流层顶是一个公认的概念，但它的定义和物理特性仍然是一个活跃的研究课题。在热带地区，世界气象组织建立的直减率对流层顶定义和温度廓线中的最低值（冷点）都用于确定对流层顶高度。我们研究了这两个定义产生的差异，使用高分辨率的空中原位测量的温度，水蒸气，和臭氧在热带对流层顶层从最近的实验在西太平洋使用美国国家航空航天局（NASA）全球鹰无人驾驶飞机系统。当这两种定义不能产生相同的对流层顶高度时，大约有一半的情况下，温度和微量气体的综合分析表明，直减率定义更好地识别了从对流层到平流层的过渡。
Although the tropopause is a well‐established concept, its definition and physical properties remain an active research topic. In the tropics, both the World Meteorological Organization established lapse rate tropopause definition and the minimum in the temperature profile (the cold point) are used to determine the tropopause height. We examine the differences produced by these two definitions using high‐resolution airborne in situ measurements of temperature, water vapor, and ozone in the tropical tropopause layer from a recent experiment over the western Pacific using the National Aeronautics and Space Administration (NASA) Global Hawk unmanned aircraft system. When the two definitions do not produce the same tropopause height, which is in about half of the cases, the combined temperature and trace gas analysis shows that the lapse rate definition better identifies the transition from the troposphere to the stratosphere.
