Comparison of Evaporation and Cold Pool Development between Single-Moment and Multimoment Bulk Microphysics Schemes in Idealized Simulations of Tornadic Thunderstorms (2010, background): “Bryan et al. (2003) suggests that grid spacings much smaller than 1 km may be necessary to properly resolve convection.”
Operational Convective-Scale Numerical Weather Prediction with the COSMO Model: Description and Sensitivities (2011, background): “Nevertheless, the resolution dependency is an important aspect when simulating deep convection (Weisman et al. 1997; Bryan et al. 2003; Roberts and Lean 2008; Weisman et al. 2008; Schwartz et al. 2010).”
Effects of Upper-Level Shear on the Structure and Maintenance of Strong Quasi-Linear Mesoscale Convective Systems (2006, methodology): “Although Bryan et al. (2003) show that interpretations of MCS structure can be altered significantly with much higher resolution, these simulations are designed to be in the class of idealized simulations of Weisman (1993) and WR04, who used a grid with 1-km horizontal spacing.2 Using the C04…”
Evaluating Mesoscale NWP Models Using Kinetic Energy Spectra (2004, methodology): “The spectra have also been used to estimate the resolution capabilities in some idealized cases (Bryan et al. 2003).”
The Maximum Intensity of Tropical Cyclones in Axisymmetric Numerical Model Simulations (2009, methodology): “, Qiu et al. 1993; Lackmann and Yablonksy 2004). As a simple check on the realism of the model output, we compare ymax to the maximum intensity reported in observational studies. In a study of the Atlantic Ocean, DeMaria and Kaplan (1994) reported a maximum intensity for Ts 5 268C of roughly 50 m s ”
The Role of Entrainment in the Diurnal Cycle of Continental Convection (2010, background): “Although 600-m resolution is considered high enough to explicitly simulate many aspects of deep convection, this is not true of shallow convection, and several studies in fact indicate that the character of deep convection changes at resolutions of 100–200 m (Petch et al. 2002; Bryan et al. 2003).”
Comparison of Two-Moment Bulk Microphysics Schemes in Idealized Supercell Thunderstorm Simulations (2011, background): “Bryan et al. (2003) argued that horizontal grid spacing of order 100 m is needed to resolve deep convection using traditional sub-grid closure assumptions in cloud models.”
Some Practical Considerations Regarding Horizontal Resolution in the First Generation of Operational Convection-Allowing NWP (2008, background): “…suggest that, for the geographical, phenomenological, and temporal parameters of this study, any added value provided by decreasing the grid increment from 4 to 2 km (with commensurate adjustments to the vertical resolution) may not be worth the considerable increases in computational expense.”
Next-Day Convection-Allowing WRF Model Guidance: A Second Look at 2-km versus 4-km Grid Spacing (2009, background): “Additionally, several studies (e.g., Petch et al. 2002; Adlerman and Droegemeier 2002; Bryan et al. 2003; Xue and Martin 2006) have demonstrated that grid spacing on the order of 1 km or less is necessary to begin resolving convective-scale circulations and generate more realism on convective scales”
Convection‐permitting models: a step‐change in rainfall forecasting (2016, background): “Real clouds have important motions on scales much smaller than those resolved by the horizontal grid lengths (1–5 km) of current CPMs. Resolutions of 100 m or higher might be needed to ‘properly’ resolve deep convective clouds (Bryan et al., 2003).”
Sensitivity of a Simulated Squall Line to Horizontal Resolution and Parameterization of Microphysics (2012, positive): “versus one-moment schemes include particle size sorting and rain evaporation (Milbrandt and Yau 2005b; Morrison et al. 2009; Luo et al. 2010). Morrison et al. (2009) found that a two-moment scheme reduced rain”

A Vortical Hot Tower Route to Tropical Cyclogenesis. (2006, background): “Although the specific details are likely to be somewhat resolution-dependent until truly cloudresolving scales are attained (e.g., Bryan et al. 2003 ), and while some of the simulated convective vorticity anomalies are spatially small (5‐10 km—arguably not well resolved here), it will be shown in u”
Mesoscale Predictability of Moist Baroclinic Waves: Convection-Permitting Experiments and Multistage Error Growth Dynamics (2007, background): “1 Convection-resolving experiments would require a grid scale well within the inertial subrange of moist cumulus convection (see e.g., Bryan et al. 2003 ).”
Cloud‐resolving model intercomparison of an MC3E squall line case: Part I—Convective updrafts (2017, background): “…have shown that finer resolution (less than 1 km horizontal grid spacing) better resolves turbulent mixing (e.g., entrainment/detrainment) and can lead to more diluted updraft cores; i.e., the area of weaker updrafts is larger [Bryan et al., 2003; Lebo and Morrison, 2015; Varble et al., 2014a].”
