Wind speed and direction explained 1664% of the variation in ground speed among seabird types. For analyses on air speed (ground speed minus apparent wind speed), we divided the 25 groups according to four flight styles: gliding, flap-gliding, glide-flapping and flapping. Tailwind speed had ...

Wind speed and direction are inputs in calculation of evapotranspiration. Wind speeds are controlled by local pressure anomalies which in turn are influenced by the temperature and local topographic features. The wind speed exhibits a wide variation not only from place to place but also during the...
In addition to the usual capabilities of an ADCP, this combination of acoustic instrumentation allows wind direction and speed to be inferred from a subsurface platform. The method of wind speed determination from ambient sound levels is explained identifying some of the techniques and limitations. ...
Tip: An easy way to tell the difference between a headwind and a tailwind is that a headwind blows towards the head (the athlete's face) while a tailwind blows towards the tail (the athlete's backside). Anemometer An anemometer is an instrument for measuring the speed of the win...
Thewind speedand direction are the most important parameters for wind resource characterisation. • The wind power depends on the air density, the area of the rotor and the cube of the wind speed. • The air density and the wind speed vary with height. ...
The effect of wind speed on aerosol optical depth (AOD) at 0.55 ??m over remote ocean regions is investigated. Remote ocean regions are defined by the combination of AOD from satellite observation and wind direction from ECMWF. According to our definition, many ocean regions cannot be taken as...
Tornado - Wind Speed, Vortex, Destruction: Fully developed tornadoes contain distinct regions of airflow. As is shown in the figure, the central axis of circulation is within the core region, a roughly cylindrical area of lower atmospheric pressure that
Wind speed and direction measurement are not necessary to measure the thermal performance of a solar system. Some performance models use this information as an input to calculate possible impact on the optical accuracy of the collector and the heliostat. However, this effect is relatively small for...
