Modelling of the near-surface wind speed
Das Wissen über die oberflächennahe Windgeschwindigkeit und deren Vorhersage ist von größtem Interesse für eine Vielzahl von Anwendungen, einschließlich der Windenergie. Für die vorliegende Arbeit wurden folgende Aspekte untersucht: i) die Variabilität des Windes in der Vergangenheit über …

The trend of wind speed over the United States during 1998 - 2011
… over the U.S., we identified a decreasing trend near the surface and an increasing trend at the upper levels, which is consistent with previous studies. The decreasing trend of near-surface wind speed is statistically significant (p<0.01). However, the statistical significance of the decreasing …

On the role of high frequency waves in ocean altimetry
… the goals are to refine satellite retrieval of wind, wind stress, and sea level using a microwave radar altimeter. The data were collected from a low-flying aircraft using a sensor suite designed to measure the surface waves, radar backscatter, the atmospheric flow, and turbulent fluxes within …

Near-surface tornado wind field estimation using damage patterns
… are considered the most violent and dangerous wind hazards and are emerging as a major public concern, causing a significant amount of property loss and casualties in the past decades. In response, the engineering community in the United States is implementing tornado-based design in codes and …

Trade wind cloud evolution observed by polarization radar: relationship to aerosol characteristics
… defined the starting or ending times of trade-wind cumuli development. The goals of this research are to: 1) investigate the characteristic time and height of warm rain formation in trade-wind cumulus using radar and 2) determine the sensitivity of precipitation development in shallow maritime …

Hydrometeorological Variability over Pakistan
… drought, rain, hail, snow, lightning, fog, wind, temperature extremes, air pollution, and climatic change. However, three of the most pressing challenges in terms of water resource availability, that are different in nature, but are inter-linked to each other are discussed over here. We …
