What Controls the Mean Depth of the PBL (2005, background): “Figure 1 is an idealized schematic depicting a variety of these regimes and the largescale environment thought to be conducive to their formation (see also Lock et al. 2000).”
Tropical and Subtropical Cloud Transitions in Weather and Climate Prediction Models: The GCSS/WGNE Pacific Cross-Section Intercomparison (GPCI) (2011, methodology): “…advances in the development of cloud and cloudy boundary layer parameterizations during the last several years (e.g., Tiedtke 1993; Del Genio et al. 1996; Fowler et al. 1996; Rasch and Kristjánsson 1998; Lock et al. 2000; Lock 2001; Bony and Emanuel 2001; Teixeira and Hogan 2002; Tompkins 2002).”
A PDF-Based Model for Boundary Layer Clouds. Part I: Method and Model Description (2002, methodology): “Lock et al. (2000) presented a parameterization consisting of various schemes coupled together, including a mass-flux convection scheme for cumulus layers, a nonlocal eddy viscosity scheme for mixed layers, and a cloud-top entrainment parameterization .”
The University of Washington Shallow Convection and Moist Turbulence Schemes and Their Impact on Climate Simulations with the Community Atmosphere Model (2009, background): “In the last few years, other AGCMs have also modernized their treatments of stratocumulus-capped PBL dynamics or shallow cumuli (e.g., Lock et al. 2000; von Salzen and McFarlane 2002; GAMDT 2004).”
Mixing‐length controls on high‐resolution simulations of convective storms (2013, neutral): “The model uses the surface-layer scheme of Best et al. (2011), the radiation scheme of Edwards and Slingo (1996), the mixed-phase cloud microphysics scheme of Wilson and Ballard (1999) and the non-local boundary-layer scheme of Lock et al. (2000).”
Vertical velocity variance and skewness in clear and cloud‐topped boundary layers as revealed by Doppler lidar (2009, methodology): “In particular, the scheme of Lock et al. (2000) categorizes boundary-layer profiles into one of six categories, five of which were identified in this study.”
The GFDL Global Atmosphere and Land Model AM4.0/LM4.0: 2. Model Description, Sensitivity Studies, and Tuning Strategies (2018, methodology): “0 continues to use Lock et al. (2000) for its boundary layer scheme, as in AM2 and AM3. In AM4.0, boundary layer clouds are also strongly affected by the PBL entrainment of free-tropospheric air, which controls the PBL depth and relative humidity in regions of little or no moist convection. In parti”
Revision of Convection and Vertical Diffusion Schemes in the NCEP Global Forecast System (2011, neutral): “To increase vertical diffusion in the cloudy region of the lower troposphere, therefore, a stratocumulus cloud-top-driven vertical diffusion scheme (Lock et al. 2000) has been incorporated into the MRF PBL model along with the new SC scheme.”
Unified treatment of dry convective and stratocumulus‐topped boundary layers in the ECMWF model (2011, background): “Cloud-top-driven diffusion is described after Lock et al. (2000) as Ktoph = 0.85κ vcld z − zmb zi − zmb ( 1 − z − zmb zi − zmb )1/2 , (15) where zi is the inversion height that could be cloud top (see definition in section 3.1) and zmb is the level below cloud base to which the top-driven mixing…”
Upgrades to the Boundary-Layer Scheme in the Met Office Numerical Weather Prediction Model (2008, methodology): “The function implemented is the ‘sharp’ function of King et al. (2001)”
