A new dynamical core for the Met Office's global and regional modelling of the atmosphere (2005, background): “Two alternative treatments of the nonlinear terms are either to extrapolate them to time-level n + 12 (McDonald and Bates 1989; Bates et al. 1993; Temperton et al. 2001) or to evaluate them at the latest available time-level and iterate (Côté et al. 1998; Cullen 2001; Yeh et al. 2002).”
Nonhydrostatic Atmospheric Models and Operational Development at JMA (2007, methodology): “Although GEM has a non-hydrostatic option (Yeh et al. 2002), the hydrostatic primitive equations are employed for operational NWP.”
Conservative Split-Explicit Time Integration Methods for the Compressible Nonhydrostatic Equations (2007, methodology): “tion with a semi-Lagrangian integration (e.g., Tanguay et al. 1990, Staniforth and Cˆot´e 1991, Yeh et al. 2002 ).”
The Evolution of Dynamical Cores for Global Atmospheric Models(125th Anniversary Issue of the Meteorological Society of Japan) (2007, background): “It has recently been extended into a nonhydrostatic version (Yeh et al. 2002). c. Net efficiency gains Hortal (1999) argued that NWP obtained an efficiency increase of a ‘‘factor of 72 by algorithmic changes in forecast model.’’”
A Multiscale Nonhydrostatic Atmospheric Model Using Centroidal Voronoi Tesselations and C-Grid Staggering (2012, methodology): “…with limited areas allowing nonhydrostatic motions, such as the exploratory efforts in the global nonhydro-static variable-resolution modeling of Yeh et al. (2002), and global high-resolution uniform-mesh modeling where nonhydrostatic scales are permitted everywhere on the globe, as in Satoh et…”
The Non-hydrostatic Icosahedral Atmospheric Model: description and development (2014, methodology): “Several authors (Semazzi et al. 1995; Cullen et al. 1997; Qian et al. 1998; Côté et al. 1998; Yeh et al. 2002; Davies et al. 2005; Wedi and Smolarkiewicz 2009; Wood et al. 2013) have used the lat-lon grid to solve a set of non-hydrostatic equations using the SLSI approach in order to acquire a large”
Staggered Vertical Discretization of the Canadian Environmental Multiscale (GEM) Model Using a Coordinate of the Log-Hydrostatic-Pressure Type (2014, methodology): “Many arguments, though, played in favor of at least a ‘‘mild’’ change of coordinate, from the original terrain following of hydrostatic-pressure type (Yeh et al. 2002) of GEM3 to one of log-hydrostatic-pressure type for GEM4 (this presently described version of GEM), which we are calling the z…”
Consistent approximate models of the global atmosphere: shallow, deep, hydrostatic, quasi‐hydrostatic and non‐hydrostatic (2005, methodology): “…centres has proceeded both with and without the inclusion of deep atmosphere effects: for example, the Meteorological Service of Canada has retained the shallow atmosphere approximation (Yeh et al. 2002) while the UK Met Office has included deep atmosphere effects (Staniforth 2001).”
A time-split nonhydrostatic atmospheric model for weather research and forecasting applications (2008, background): “This staggering is used in most nonhydrostatic NWP and research models (e.g. ARPS [45], COAMPS [14], RAMS [30], LM [8], GEM [46], MC2 [3], UKMO Unified Model [38], JMA Nonhydrostatic model [32]) because it provides the most accurate representation of gravity waves (horizontally-divergent modes, [26]”
