Commentaries on Top-Cited Boundary-Layer Meteorology Articles
Garratt, John ; Wilczak, James ; Holtslag, Albert ; Schmid, Hans Peter ; Grachev, Andrey ; Beljaars, Anton ; Foken, Thomas ; Chen, Fei ; Fairall, Christopher ; Hicks, Bruce ; Kusaka, Hiroyuki ; Martilli, Alberto ; Masson, Valéry ; Mauder, Matthias ; Oncley, Steven ; Rotach, Mathias ; Tjernström, Michael
Brief critiques are given for:<br> 1. Articles related to flux?gradient relations and eddy-correlation measurements, viz. Dyer (1974), Louis (1979), Moore (1986), Wilczak et al. (2001), Finnigan et al. (2003; together with Finnigan 2004).<br> 2. Articles related to PBL modelling, viz. Deardorff (1980) and Troen and Mahrt (1986).<br> 3. Articles related to urban meteorology, specifically urban canopy schemes, viz. Masson (2000), Kusaka et al. (2001), and Martilli et al. (2002).<br>These actually provide an interesting and very informative glimpse of the historical development of techniques that underpin key components of contemporary measurement and numerical methodologies. Several of these articles complement others that appeared in other journals-we have in mind one that JRG was closely associated with, viz. Webb et al. (1980) regarding the influence of density fluctuations on measured eddy covariances. Another is associated with the pioneering numerical investigations of James Deardorff on the neutral and unstable planetary boundary layers, with and without clouds, viz. Deardorff (1972).<br>Unfortunately, not all invited contributions arrived in good time, and in the spirit of Corporal Jones' 'Don't panic, don't panic' (refer BBC TV, circa 1970) JRG asked, at short notice, the authors of Wilczak et al. (2001), Masson (2000), and Martilli et al. (2002) to submit short comments on their own articles. They rose to the challenge, and are included, even though Hans Peter Schmid's critique of Wilczak et al. (2001), Finnigan et al. (2003), and Finnigan (2004) arrived just in time to be included!<br>For practical purposes, acronyms (e.g., MOST) and initialisms (e.g., NWP) are defined here for use in all commentaries. Some are not defined at all, but may be found in the appropriate reference (e.g., COARE, KEYPS). I mention: LES?=?large-eddy simulation, MOST?=?Monin?Obukhov similarity theory, NWP?=?numerical weather prediction, PBL?=?planetary boundary layer, TKE?=?turbulence kinetic energy.</p>
