Tropical tropopause layer (2009, result): “Other modeling studies employ different mechanisms [e.g., Johnson et al., 2001; Dessler and Sherwood, 2003; Gettelman and Webster, 2005] to arrive at results broadly in agreement with observations.”
A Model for Transport across the Tropical Tropopause. (2001, methodology): “However, the simulated gradients of water and ozone are consistent in sign with those observed and with the observations reported by Sherwood and Dessler (2000). d. Sensitivity to model parameters The only interesting features of the simulations that showed sensitivity to model parameters were the…”
Tropical troposphere‐to‐stratosphere transport inferred from trajectory calculations (2004, background): “Sherwood and Dessler [2000] termed this layer the ‘‘tropical tropopause layer’’ (TTL) and defined its boundaries to be the level of zero net radiative heating (� 350 K) and the highest level that convection reaches (� 420 K). Air in this layer is considered to slowly ascend through net radiative he”
Stratospheric water vapor predicted from the Lagrangian temperature history of air entering the stratosphere in the tropics (2005, background): “…cirrus as ''dehydration engines'' [Danielsen, 1982], or that deep, overshooting convection could inject air into the tropopause region which is drier than expected from the saturation mixing ratio of the surrounding synoptic-scale temperature field [Danielsen, 1993; Sherwood and Dessler, 2000].”
How Well Do We Understand and Evaluate Climate Change Feedback Processes (2006, background): “…the troposphere to the lower stratosphere: recent observations suggest that convective and gradual ascent processes, at least, play important roles, but the relative importance of both remains a matter of debate (Keith 2000; Sherwood and Dessler 2000; Webster and Heymsfield 2003; Rosenlof 2003).”
Control of interannual and longer‐term variability of stratospheric water vapor (2005, background): “…limited to a few parts per million by volume (ppmv) by the extremely low temperatures at the tropical tropopause, but the details of the processes that control [H 2 O] e remain controversial [Newell and Gould-Stewart, 1981; Danielsen, 1993; Sherwood and Dessler, 2000; Holton and Gettelman, 2001].”
Global distribution of convection penetrating the tropical tropopause (2005, background): “Some studies suggest that the deep convection has an important impact on the water vapor budget [Sherwood and Dessler, 2000].”
Detection of tropical deep convective clouds from AMSU-B water vapor channels measurements (2005, background): “The tropical tropopause layer (TTL) between about 14–18 km [e.g., Sherwood and Dessler, 2000, 2001; Alcala and Dessler, 2002] is the important transition layer between the convectively dominated tropical troposphere and the radiatively controlled stratosphere [e.g., Highwood and Hoskins, 1998;…”
The Global Circulation of the Atmosphere (2021, background): “The most prominent dry air pool in the atmosphere is found in the subtropics, and over the next several years a number of investigators developed an interest in large scale control of subtropical humidity, employing Lagrangian techniques (Emanuel and Pierrehumbert, 1996; Salathe and Hartmann, 1997; ”
