The use of polarized light in the zonal orientation of the sandhopper Talitrus saltator (Montagu) by Alberto Ugolini, Takahiko Hariyama, David C. Wilcockson, Luca Mercatelli

“…The bowl was covered by a blue gelatin filter with a grey filter (control condition) and a linear polarizing filter (experimental conditions) positioned under the blue one in such a way as to occupy half of the upper surface of the Plexiglas bowl so as to create a linear polarization gradient. …”

Temporally and zonally varying atmospheric waveguides – climatologies and connections to quasi-stationary waves by R. H. White, L. Mareshet Admasu

“…Conversely, the background flow for the KS waveguides is calculated using time and zonal filtering. We isolate the impacts of the background flow methodology from the different waveguide definitions by calculating PV waveguides using the same background flow calculation method as the KS waveguides. …”

Blocking Detection Based on Synoptic Filters by Bernd Schalge, Richard Blender, Klaus Fraedrich

“…We introduce three blocking filters and analyse their sensitivities: (i) a quantile filter requiring a minimum geopotential height anomaly to reject cut-off lows, (ii) an extent filter to extract scales above a minimum zonal width, and (iii) a persistence filter to extract events with a minimum duration. …”

Climatology of mesopause region nocturnal temperature, zonal wind and sodium density observed by sodium lidar over Hefei, China (32° N, 117° E) by T. Li, C. Ban, C. Ban, X. Fang, J. Li, Z. Wu, W. Feng, W. Feng, J. M. C. Plane, J. Xiong, D. R. Marsh, M. J. Mills, X. Dou

“…The large zonal momentum flux in summer and winter due to short-period GWs is clearly anticorrelated with eastward zonal wind maxima below 90 km, suggesting the filtering of short-period GWs by the SAO wind.…”

Reducing Forecast Errors of a Regional Climate Model Using Adaptive Filters by Michel Pompeu Tcheou, Lisandro Lovisolo, Alexandre Ribeiro Freitas, Sin Chan Chou

“…The K-means unsupervised learning algorithm is used to obtain the number of filters to employ from the climate variables. The proposed approach is applied to some climate variables such as the meridional wind, zonal wind, and the geopotential height. …”

Long term variations of atmospheric synoptic variability: A study based on radiosonde data from Lindenberg (Germany) by Martin Göber, Andreas Hense

“…For the time interval 1971-90 we find that the already described significant increase of monthly mean tropospheric temperature and mean zonal wind is accompanied both by changes of different transports carried out by the time mean circulation and by significant changes of monthly variances and transports by eddies of different scales. …”

On Interface Issues in LES/RANS Coupling Strategies: A Method for Turbulence Forcing by Suad JAKIRLIC, Björn KNIESNER, Gisa KADAVELIL

“…The present work deals with a computational strategy coupling near-wall, eddyviscosity-based RANS models with LES within a zonal Hybrid LES/RANS (HLR) framework. Key questions concerning the coupling of both methods, the inherently steady RANS method and highly-unsteady LES method, are closely connected to the treatment at the interface separating both sub-regions. …”

Development of a High-Resolution Wind Forecast System Based on the WRF Model and a Hybrid Kalman-Bayesian Filter by Carlos Otero-Casal, Platon Patlakas, Miguel A. Prósper, George Galanis, Gonzalo Miguez-Macho

“…A period of one year is simulated at 333 m horizontal resolution, with a daily operational forecasting set-up. The Kalman-Bayesian filter was tested both directly on wind speed and on the U-V (zonal and meridional) components for nowcasting periods from 10 min to 6 h periods, all of them with important applications in the wind industry. …”
