Abstract As offshore wind power is continuously integrated into the electric systems in around world, it critical to understand its variability. Weather regimes (WRs) can provide meteorological explanations for fluctuations power. Instead of relying on traditional large-scale circulation WRs, this study focuses assessing dependency resources WRs tailored region clustered based finer spatial sca...
Morphodynamic changes at sandy coasts, as are dominant in The Netherlands, are typically monitored at yearly intervals by means of LIDAR. Meanwhile it is recognized that beach morphodynamics is not a regular process but is strongly correlated to meteorological conditions. A time series of 14 terrestrial laser scans of a beach experiment is analyzed, obtained during a time period of 88 hours cha...
Two key elements in predicting odour response are the estimation of peak (few seconds) ground-level concentrations and the evaluation of the likelihood of a consequent adverse response. Peak rather than ensemble-average concentrations are not easily predicted by current dispersion models. The required peak-to-mean ratios depend on source characteristics, downwind distance and atmospheric stabil...
Physical conditions in the atmospheres of tidally locked, slowly rotating hot Jupiters correspond to dynamical circulation regimes with Rhines scales and Rossby deformation radii comparable to the planetary radii. Consequently, the large spatial scales of moving atmospheric structures could generate significant photospheric variability. Here, we estimate the level of thermal infrared variabilit...
This paper documents the main features of the weather, climate and climate variability over Andes cordillera in South America on the basis of instrumental observations. We first provide a basic physical understanding of the mean annual cycle of the atmospheric circulation and precipitation and over the Andes and adjacent lowlands. In particular, the diversity of precipitation, temperature and w...
Traceability of pitch angle position for small scale wind turbine to get a maximum Energy Extraction
Global crisis in financial, energy, together with climate and enviromental, has motivated word community to seek for alternative energy resourses, known as the new and renewable energy source to replace conventional widely used fossil energy. Wind energy, regarded as potential candidate of the clean alternative source that may help to solve the crisis. The development of the world’s wind turbin...
S afety-critical systems appear in several application areas, such as transportation and air-traffi c control systems, nuclear plants, space systems, and operating rooms in hospitals. Reliable control of these systems requires not only meeting performance specifi ca-tions in the presence of multiple constraints, which together ensure predictable response of the overall system and safe operation...
The IEA Wind agreement, also known as the Implementing Agreement for Cooperation in the Research, Development, and Deployment of Wind Energy Systems, functions within a framework created by the International Energy Agency (IEA). Views, findings, and publications of IEA Wind do not necessarily represent the views or policies of the IEA Secretariat or of all its individual member countries. Exper...
The extreme high winds, intense rainfall, large ocean waves, and copious sea spray in hurricanes push the surface-exchange parameters for temperature, water vapor, and momentum into untested regimes. The Coupled Boundary Layer Air–Sea Transfer (CBLAST)-Hurricane program is aimed at developing improved coupling parameterizations (using the observations collected during the CBLAST-Hurricane field...
Mexico City lies in a high altitude basin where air quality and pollutant fate is strongly influenced by local winds. The combination of high terrain with weak synoptic forcing leads to weak and variable winds with complex circulation patterns. A gap wind entering the basin in the afternoon leads to very different wind convergence lines over the city depending on the meteorological conditions. ...
