An inherently mass‐conserving semi‐implicit semi‐Lagrangian discretization of the deep‐atmosphere global non‐hydrostatic equations (2014, methodology): “Developing the shallow-atmosphere rotation matrix approaches of Côté (1988) and Temperton et al. (2001), Staniforth et al. (2010) show how, within a deep-atmosphere context, this issue can be addressed by defining a rotation matrix M, the elements of which depend on the particular coordinate…”
Horizontal grids for global weather and climate prediction models: a review (2012, methodology): “The spectral method can be adapted to use a reduced Gaussian grid (Temperton et al., 2001) whilst avoiding most of the issues of reduced lat–lon grids mentioned above.”
Dynamical kernel of the Aladin–NH spectral limited‐area model: Revised formulation and sensitivity experiments (2010, methodology): “The 2-TL SL time discretization follows that of the IFS/ARPEGE model (Temperton et al., 2001) and uses the so-called ‘SETTLS’ time extrapolation (Hortal, 2002).”
Climate model configurations of the ECMWF Integrated Forecasting System (ECMWF-IFS cycle 43r1) for HighResMIP (2018, background): “…on a hydrostatic, semi-Lagrangian, semi-implicit dynamical core with computations alternated between spectral and reduced Gaussian grid-point representations each time step (Hortal and Simmons, 1991; Hortal, 2002; Ritchie et al., 1995; Simmons et al., 1989; Temperton, 1991; Temperton et al., 2001).”
20-km-Mesh Global Climate Simulations Using JMA-GSM Model —Mean Climate States— (2006, methodology): “Furthermore, a two-time-level semiLagrangian scheme has been introduced instead of a three-time-level scheme, which provides a doubling of efficiency in principle (Temperton et al. 2001; Hortal 2002; Yoshimura and Matsumura 2005).”
Tropospheric chemistry in the integrated forecasting system of ECMWF (2014, methodology): “At the start of the time step, the three-dimensional advection of the tracers mass mixing ratios is simulated by the SL method as described in Temperton et al. (2001) and Hortal (2002).”
Description of the NCAR Community Atmosphere Model (CAM 3.0) (2004, background): “In addition Hortal’s modification [Temperton et al., 2001] is included, in which d dt [ − ( psB ∂T ∂p )”
A new dynamical core for the Met Office's global and regional modelling of the atmosphere (2005, methodology): “The case for using the deep-atmosphere equations is discussed by White and Bromley (1995) and White et al. (2005), and primarily amounts to the desirability of retaining a complete representation of the Coriolis force.”
Ensemble forecasting (2008, methodology): “The numerical weather prediction model used for all forecasts is a two-time-level semi-Lagrangian global spectral model [33].”
