The predictability of the extratropical stratosphere on monthly time‐scales and its impact on the skill of tropospheric forecasts (2015, background): “However, a few general-circulation models have been shown to be able to simulate the evolution of the QBO (Takahashi, 1996; Scaife et al., 2000; Giorgetta et al., 2002; Kim et al., 2013).”
Using Satellite Observations to Constrain Parameterizations of Gravity Wave Effects for Global Models (2006, background): “Gravity waves are now known to also influence the stratospheric circulation in the spring and summer seasons (Alexander and Rosenlof 1996; Scaife et al. 2002) and in the tropical lower stratosphere (Dunkerton 1997; Giorgetta et al. 2002 ).”
Reconstructing, Monitoring, and Predicting Multidecadal-Scale Changes in the North Atlantic Thermohaline Circulation with Sea Surface Temperature (2004, methodology): “A high vertical resolution version of ECHAM5 has been used by Giorgetta et al. (2002) to study the dynamics of the stratospheric quasi-biennial oscillation (QBO).”
Improved Middle Atmosphere Climate and Forecasts in the ECMWF Model through a Nonorographic Gravity Wave Drag Parameterization (2010, background): “The primary source of the resolved waves is parameterized deep convection in the tropics (e.g., Giorgetta et al. 2002).”
Recent developments in gravity‐wave effects in climate models and the global distribution of gravity‐wave momentum flux from observations and models (2010, background): “…general circulation models (AGCMs) are effective tools with which to study the role of atmospheric waves in driving the QBO (Takahashi 1996, 1999; Horinouchi and Yoden 1998; Hamilton et al., 1999, 2001; Giorgetta et al., 2002, 2006; Shibata and Deushi 2005; Kawatani et al., 2005, 2010a, 2010b).”
Global estimates of gravity wave momentum flux from High Resolution Dynamics Limb Sounder observations (2008, methodology): “In the ECHAM4 model experiments of Manzini and McFarlane [1998] and Giorgetta et al. [2002] , which gave realistic middle atmosphere circulations, the parameterized gravity wave momentum flux at the tropopause was also a local minimum at the equator.”
Implementation of a gravity wave source spectrum parameterization dependent on the properties of convection in the Whole Atmosphere Community Climate Model (WACCM) (2005, methodology): “Giorgetta et al. [2002] have shown that a resolution of � 1 km or less is required for a GCM to be able to model a QBO, whereas the WACCM2 resolution in this region is closer to 1.5 km. [47] In summary, we have successfully implemented a more physically based source spectrum parameterization of con”
Improved 11‐year solar signal in the Freie Universität Berlin Climate Middle Atmosphere Model (FUB‐CMAM) (2004, methodology): “The generation of a realistic model-QBO would need sufficient spatial resolution, a gravity wave parameterization and a realistic simulation of tropical convection [e.g., Giorgetta et al., 2002 ].”
Impact of the QBO on surface winter climate (2009, background): “While a few atmosphere general circulation models (AGCM) are able to reproduce the evolution of the QBO [e.g., Takahashi, 1996; Scaife et al., 2000; Giorgetta et al., 2002 ], many simulate a tropical stratosphere with mean easterly winds instead of QBO-like oscillations [Boer and Hamilton, 2008].”
The Roles of Equatorial Trapped Waves and Internal Inertia–Gravity Waves in Driving the Quasi-Biennial Oscillation. Part I: Zonal Mean Wave Forcing (2010, background): “Atmospheric general circulation models (AGCMs) are effective tools with which to study the roles of atmospheric waves in driving the QBO (Takahashi 1996, 1999; Horinouchi and Yoden 1998; Giorgetta et al. 2002, 2006; Hamilton et al. 1999, 2001; Shibata and Deushi 2005a,b; Kawatani et al. 2005).”
Predictability of the quasi‐biennial oscillation and its northern winter teleconnection on seasonal to decadal timescales (2014, methodology): “However, a few climate models, including the models used here, now successfully simulate the QBO through the combined forcing from resolved waves and the parameterization of nonorographic gravity wave momentum fluxes [Scaife et al., 2000; Giorgetta et al., 2002; Scinocca et al., 2008].”
