Tropical troposphere‐to‐stratosphere transport inferred from trajectory calculations (2004, background): “It was suggested by Sherwood [2000] and Holton and Gettelman [2001] that air masses in this region rather descend than ascend.”
Radiation balance of the tropical tropopause layer (2004, background): “These processes include cumulus convection which overshoots its level of neutral buoyancy [Sherwood, 2000], large-scale waves [Fujiwara et al., 2001], horizontal transport and slow diabatic ascent [ Holton and Gettelman, 2001 ].”
Impact of the vertical velocity scheme on modeling transport in the tropical tropopause layer (2010, background): “However, the importance of different mechanisms, such as horizontal advection [ Holton and Gettelman, 2001 ], convective overshooting [Danielsen, 1982], in particular above continental areas [Ricaud et al., 2007] and mixing [Konopka et al., 2007], for transport from the main convective outflow to th”
Trends in the temperature and water vapor content of the tropical lower stratosphere: Sea surface connection (2008, background): “Although the temperature change appears limited in longitudinal scope, it can still have an impact on zonal distribution of lower stratospheric water vapor, as demonstrated in the model of Holton and Gettelman [2001] .”
Stratospheric water vapor predicted from the Lagrangian temperature history of air entering the stratosphere in the tropics (2005, background): “Holton and Gettelman [2001] pointed out that horizontal advection of air through the coldest regions rather than enhanced vertical motion in those regions, could resolve the discrepancy between esti-JOURNAL OF GEOPHYSICAL RESEARCH, VOL.”
Interannual changes of stratospheric water vapor and correlations with tropical tropopause temperatures (2004, background): “... temperatures over 108N‐ 108S are substantially larger than observed (Fig. 15), this can be reconciled by the observed latitudinal spreading of the tropical signal to ;408N‐408S, so that the forced tropical signal is ‘‘diluted.’’ The observation that interannual changes in water vapor are closely”
Control of interannual and longer‐term variability of stratospheric water vapor (2005, background): “It is widely agreed that the water vapor mixing ratio of air entering the stratosphere (henceforth [H2O]e) is 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 [H2O]e remain controversial [N”
Modeling atmospheric stable water isotopes and the potential for constraining cloud processes and stratosphere‐troposphere water exchange (2005, background): “…include (a) the gradual ascent of water vapor that undergoes freeze-drying at the tropical tropopause, (b) uplift of thin cirrus ice particles and (c) episodic lofting of ice by deep convective overshoot [Holton et al., 1995; Holton and Gettelman, 2001; Sherwood and Dessler, 2001] (among others).”
Tropical stratospheric aerosol layer from CALIPSO lidar observations (2009, background): “Indeed, aside from the known minimum vertical velocity around 20 km at the bottom of the BD circulation [Hartmann et al., 2001; Holton and Gettelman, 2001; Corti et al., 2005; Fu et al., 2007; Yang et al., 2008].”
