A Diagnostic for Evaluating the Representation of Turbulence in Atmospheric Models at the Kilometric Scale (2011, neutral): “Wyngaard (2004) studied this region, which he called ‘‘terra incognita.’’”
Exchange Processes in the Atmospheric Boundary Layer Over Mountainous Terrain (2018, background): “In addition, parameterization schemes that are appropriate at coarse resolutions may be inadequate for km-scale or sub-km-scale simulations, in particular for ABL mixing [232].”
A review on regional convection‐permitting climate modeling: Demonstrations, prospects, and challenges (2015, background): “3, the assumptions made in the applied turbulence parameterizations break down at kilometer-scale grid spacings [Wyngaard, 2004; Moeng et al., 2010].”
Convectively Induced Secondary Circulations in Fine-Grid Mesoscale Numerical Weather Prediction Models (2014, methodology): “This deficiency is one of the consequences of the terra incognita described by Wyngaard (2004).”
The Persistent Challenge of Surface Heterogeneity in Boundary-Layer Meteorology: A Review (2020, result): “The direction of this distortion and how to correct for it may be compared to the terra-incognita problem postulated for parameterizing turbulence in the ABL at intermediate model resolution (Wyngaard 2004).”
Mixing‐length controls on high‐resolution simulations of convective storms (2013, neutral): “This regime has been termed the ‘terra incognita’ by Wyngaard (2004) or ‘grey-zone’ of turbulence and it has been studied by several authors (e.g. Craig and Dörnbrack, 2008; Parodi and Tanelli, 2010; Honnert et al., 2011; Beare, 2014).”
Toward Convective-Scale Prediction within the Next Generation Global Prediction System (2019, methodology): “When the grid is locally refined to 4 km, the model enters the so-called planetary boundary layer gray zone (Wyngaard 2004), and the current GFS physics parameterizations may not optimally represent either the high-resolution area or the lower-resolution area on the opposite side of Earth.”
Nested Mesoscale Large-Eddy Simulations with WRF: Performance in Real Test Cases (2012, background): “As discussed by Wyngaard (2004), both the ﬁnest mesoscale simulation and the coarsest LES might fall in what he termed ‘‘terra incognita’’—a region where Reynolds-averaged closures can be problematic, since some turbulent ﬂuxes might be resolved, and where LES is also challenging since the grid…”
Implementation of a Nonlinear Subfilter Turbulence Stress Model for Large-Eddy Simulation in the Advanced Research WRF Model (2010, background): “Wyngaard (2004) provides an important discussion regarding some challenges associated with modeling the scales of motion between those for which LES is suitable and those for which a large-scale PBL parameterization is appropriate.”
Representation of the Subgrid-Scale Turbulent Transport in Convective Boundary Layers at Gray-Zone Resolutions (2015, background): “The gray zone for the SGS turbulence models is also called ‘‘terra incognita’’ by the pioneering study addressing this issue (Wyngaard 2004).”
Parametrization of Drag and Turbulence for Urban Neighbourhoods with Trees (2015, background): “Due to computational limitations, mesoscale model grid resolution has an upper limit on the order of 102–103m (issues of turbulence parametrization aside, e.g., see Wyngaard 2004).”
The Non-hydrostatic Icosahedral Atmospheric Model: description and development (2014, background): “It is a challenging issue to parameterize turbulent transport processes in such an intermediate resolution (Wyngaard 2004), and continuous efforts are needed to improve the subgrid-scale turbulence parameterization schemes along with shallow cumulus convection.”
Large-Eddy Simulations and Observations of Atmospheric Marine Boundary Layers above Nonequilibrium Surface Waves (2008, methodology): “We note that SGS modeling is an active research area and numerous alternate approaches to modeling these SGS variables are available (e.g., Meneveau and Katz 2000; Geurts 2001; Sullivan et al. 2003; Wyngaard 2004; Sullivan et al. 2006a; Hatlee and Wyngaard 2007).”
The Effect of Mesh Resolution on Convective Boundary Layer Statistics and Structures Generated by Large-Eddy Simulation (2011, methodology): “Potentially, this can be improved by utilizing a fuller set of rate equations for subgrid-scale variables (e.g., Wyngaard 2004b; Hatlee and Wyngaard 2007).”
Evaluation of the convection‐resolving climate modeling approach on continental scales (2017, background): “Grid spacings of O(1 km) are comparable to the size of the particularly energetic eddies in the planetary boundary layer [Wyngaard, 2004; Zhou et al., 2014], and consequentially, turbulent processes as well as the dominant turbulent length scale are still underresolved [Bryan et al.”
Examining Two-Way Grid Nesting for Large Eddy Simulation of the PBL Using the WRF Model (2007, methodology): “A careful design of subgrid mixing that blends the ensemble-mean PBL scheme to the LES type of SGS model is needed (Wyngaard 2004).”
