RF stands for "Range Folding". The true wind direction can be determined on a radial velocity plot only where the radial velocity is zero (grey colors). Where you see a grey area, draw an arrow ...

Keep tabs on the wind speed and direction any day. These factors can have a huge impact on temperature and weather in general – simply because of our proximity to Lake Michigan.

Depending on the characteristics and availability of the sediment supply, dominant wind velocity and direction, moisture and vegetation present, and the geomorphology of the nearshore and beach ...

Astronomers from the University of Sheffield and Pennsylvania State University have performed X-ray and optical observations ...

Wind direction can be calculated by taking velocity readings from two ultrasonic sensor pairs perpendicular to each other and using a bit of simple trigonometry. For an ultrasonic anemometer to ...

"Here at the Santee Cooper lakes, wind velocity and direction can combine to create dangerous conditions. This is a legendary ...

To measure wind speed and direction ... pulse outputs and processing of the received signal to calculate direction and velocity. The ultrasonic transducers are mounted in a circular baseplate ...
