Journal ArticleDOI
Improvements in wind speed forecasts for wind power prediction purposes using Kalman filtering
P. Louka,P. Louka,George Galanis,George Galanis,N. Siebert,Georges Kariniotakis,Petros Katsafados,Ioannis Pytharoulis,Ioannis Pytharoulis,George Kallos +9 more
TL;DR: The results obtained showed a remarkable improvement in the model forecasting skill, with a significant reduction of the required CPU time in the case of wind power prediction.
Journal ArticleDOI
Coupling between air flow in streets and the well-developed boundary layer aloft
TL;DR: In this paper, the mean and turbulent characteristics of air flow within and above, a street under neutral stratication were studied and compared with the mean wind and turbulent statistics over smoother terrain.
Journal ArticleDOI
Thermal Effects on the Airflow in a Street Canyon – Nantes'99 Experimental Results and Model Simulations
TL;DR: In this article, the authors examined the thermal effects on the airflow within a street canyon, which are produced by the variation of direct solar heating of the street sides and ground, using the standard k-e model.
Journal ArticleDOI
Applications of Kalman filters based on non-linear functions to numerical weather predictions
George Galanis,George Galanis,P. Louka,P. Louka,Petros Katsafados,Ioannis Pytharoulis,Ioannis Pytharoulis,George Kallos +7 more
TL;DR: It is shown that in both cases, a polynomial of low order is adequate for eliminating any systematic error, while higher order functions lead to instabilities in the filtered results having, at the same time, trivial contribution to the filter.
Journal ArticleDOI
An improved limited area model for describing the dust cycle in the atmosphere
TL;DR: In this paper, a combined effort was devoted to upgrading the SKIRON/Dust forecasting system by incorporating new features for the description of the lower boundary characteristics of the atmospheric model and the dust aerosol properties.
