Low frequency variability of tropical cyclone potential intensity 1. Interannual to interdecadal variability (2002, methodology): “It is also possible that the spurious cooling is related to the anomalously warm tropical tropopause in the Reanalysis as compared to radiosonde temperatures in 1989–1993 [Randel et al., 2000].”
On The Relationship between the QBO and Tropical Deep Convection (2003, methodology): “As predicted by theory, the zonal mean tropopause is higher than normal (lower pressure) near the equator and slightly lower than normal in the subtropics during the east phase (Fig. 3c; also see Huesmann and Hitchman 2001; Randel et al. 2000).”
The Teleconnection of El Niño Southern Oscillation to the Stratosphere (2019, background): “This warming in the troposphere is associated with lower stratospheric cooling aloft (Figures 5a and 5c; Gettelman et al., 2001; Kiladis et al., 2001; Yulaeva & Wallace, 1994; Randel & Cobb, 1994; Randel et al., 2000; Scherllin-Pirscher et al., 2012; X. L. Zhou et al., 2001).”
Stratospheric water vapor trends over Boulder, Colorado: Analysis of the 30 year Boulder record (2011, background): “The trend strength diminished somewhat with altitude from 16 to 28 km, suggesting a tropical water vapor increase as the source, but several studies of long‐term changes in cold‐point temperatures near the tropical tropopause found cooling instead of warming trends for this period [e.g., Simmons et ”
Cause of the widening of the tropical belt since 1958 (2008, methodology): “There are warnings against using the reanalysis data prior to 1979 (the beginning of assimilation of satellite data into the reanalysis) for the study of multidecadal variability [Randel et al., 2000].”
Climatological characteristics of the tropical tropopause as revealed by radiosondes (2001, methodology): “[2000a] report a coarser resolution, and that of the NCEP reanalysis is about 2 km (20–30 hPa) [Randel et al., 2000].”
Thermal variability of the tropical tropopause region derived from GPS/MET observations (2003, background): “, 2001], or operational meteorological analyses, with relatively low vertical resolution and attendant biases [e.g., Hoinka, 1999; Randel et al., 2000].”
Effect of convection on the summertime extratropical lower stratosphere (2004, methodology): “To account for a known warm bias in the UKMO fields [Randel et al., 2000], we adjust the temperatures downward: temperatures below 200 K are reduced by 3 K, temperatures between 200 and 220 K are reduced by an offset that linearly decreases from 3 K at 200 K to 0 at 220 K, temperatures above 220 K a”
Trends in the temperature and water vapor content of the tropical lower stratosphere: Sea surface connection (2008, background): “The NOAA Boulder (40N) long-term frost point research balloon record shows increases in water over a 20–25 year period, while the temperature record shows cooling at the tropical tropopause [ Randel et al., 2000, 2006 ].”
Variability and trends in the global tropopause estimated from radiosonde data (2006, methodology): “[24] On multidecadal timescales, the global tropopause height rises with a warming troposphere and cooling stratosphere, in both climate models and reanalysis data sets (Sausen and Santer [2003] and Santer et al.”
Behavior of tropopause height and atmospheric temperature in models, reanalyses, and observations: Decadal changes (2003, methodology): “…show an increase in the height of the tropo-pause over the last several decades or longer, either at individual radiosonde stations [ Steinbrecht et al. , 1998], networks of stations in the tropics [ Seidel et al. , 2001], or in tropical averages from reanalysis products [ Randel et al. , 2000].”
Signals of El Niño Modoki in the tropical tropopause layer and stratosphere (2012, background): “4a are in agreement with the results of previous studies (e.g., Randel et al., 2000; Scaife et al., 2003; Xie et al., 2011).”
Introduction to the SPARC Reanalysis Intercomparison Project (S-RIP) and overview of the reanalysis systems (2016, background): “Other chapters will only include a subset of these reanalysis data sets, since some reanalyses have already been shown to perform poorly for certain diagnostics (e.g. Pawson and Fiorino, 1998; Randel et al., 2000; Manney et al., 2003, 2005; Birner et al., 2006; Monge-Sanz et al., 2007; Sakazaki et a”
The Response of Tropospheric Circulation to Perturbations in Lower-Stratospheric Temperature (2005, unknown): “The time period that is covered is January 1979–May 2002; earlier data are not used because of the well-known problem with the reanalysis in the stratosphere before the incorporation of satellite data in 1979 (see, e.g., Randel et al. 2000; Haigh 2003).”
SAGE II measurements of stratospheric aerosol properties at non-volcanic levels (2007, background): “Randel et al. [2000] has reported that the NCEP tropopause temperature is too warm by approximately 3-5 K.”
Recent widening of the tropical belt: Evidence from tropopause observations (2007, methodology): “period since 1979 because of inhomogeneities in the prior data [Randel et al., 2000].”
