The impact of cirrus clouds on tropical troposphere-to-stratosphere transport (2006, unknown): “Speciﬁcally, absorption of infrared radiation in upper tropospheric cirrus leads to enhanced upwelling. that this transport mechanism is too rare for being responsible for TST (Gettelman et al., 2002; Kupper et al., 2004).”
Tropical troposphere‐to‐stratosphere transport inferred from trajectory calculations (2004, background): “Gettelman et al. [2002a] presented an analysis of tropical deep convection, focusing on the fraction of convection that penetrates the tropical tropopause (� 0.5%).”
Radiation balance of the tropical tropopause layer (2004, background): “Convection dominates the lower portion of the TTL, but the frequency of convection declines rapidly with height [Gettelman et al., 2002].”
Detection of tropical deep convective clouds from AMSU-B water vapor channels measurements (2005, methodology): “…over oceans, satellite data including passive measurements of visible, infrared, and microwave radiances and active measurements of radar have been used in the studies of deep convective clouds [e.g., Liu et al., 1995; Hall and Haar, 1999; Gettelman et al., 2002; Alcala and Dessler, 2002].”
Global distribution of convection penetrating the tropical tropopause (2005, methodology): “5 , 6 hour interval NCEP reanalysis data described by Kistler et al. [2001]. After recording the general information of PF size (total pixel numbers), mean rain rate, convective rain contribution etc., the convective intensity proxies for each PF, such as minimum 85 GHz Polarization Corrected Temper”
Thermal variability of the tropical tropopause region derived from GPS/MET observations (2003, methodology): “We note that tropical convection rarely penetrates above 14 km [e.g., Gettelman et al., 2002], so that the patterns revealed in these correlations represent temperatures mostly above the convective region.”
Underestimation of deep convective cloud tops by thermal imagery (2004, background): “Cumulus mixing effects near the tropopause, which may be important for tracer transport and energy budgets [Fromm and Servranckx, 2003; Gettelman et al., 2002; Sherwood et al., 2003], are also sensitive to small changes in penetration depth.”
Tropical tropopause layer (2009, background): “During boreal winter, transport processes are thought to be responsible for shifting minimum concentrations to regions north of the equator [Gettelman et al., 2002a], and during boreal summer the Indian/Southeast Asian monsoon leads to exceptionally high water vapor concentrations north of the…”
Effect of convection on the summertime extratropical lower stratosphere (2004, background): “In the tropics, convection to the altitude of the tropopause and above does occur [e.g., Alcala and Dessler, 2002; Gettelman et al., 2002] and appears to play a role in determining the abundance of trace species there [e.”
A Climatology of the Tropical Tropopause Layer (2002, background): “A small fraction of the time, convection penetrates above the cold point in isolated locations and seasons ( Gettelman et al. 2002 ).”
Horizontal transport and the dehydration of the stratosphere (2001, background): “Furthermore, recent studies [e.g., Highwood and Hoskins, 1998; Folkins et al., 1999; Gettelman et al., 2001] suggest that overshooting of tropical convection into the interior of the TTL is not a common occurrence, and that the characteristics of the bulk of the TTL are not primarily controlled by…”
Impact of monsoon circulations on the upper troposphere and lower stratosphere (2004, background): “However, there may exist a dry bias in HALOE, especially below the tropopause, because HALOE cannot retrieve in the presence of clouds, and the Asian monsoon region is one of the regions with the highest frequency of convective clouds at and above the tropopause [Gettelman et al., 2002].”
Stratospheric water vapor predicted from the Lagrangian temperature history of air entering the stratosphere in the tropics (2005, background): “Although due care should be used when interpreting the red contour lines as the ECMWF velocity fields almost certainly represent convective transport poorly, we find that these locations are in general agreement with the spatial distributions of deep convection derived from, for example, cloud top b”
