Each of the three models was tested with approach wind directions from 0° to 90°, in 15° increments. It was observed that speed-up can vary significantly depending on the approaching wind direction. The effect of wind direction on speed-up was also investigated using field data from a ...
A numerical model has been used to investigate the wind-driven circulation in a stratified basin of moderate size, Lake Tahoe, California-Nevada. Two types of circulation are identified: direct circulations, in which the current directions remain relatively constant and the mean circulation formed ove...
refraction directionsclassical wave refraction calculationswind waveUSADirectional wave spectra calculated from digitized synthetic aperture radar (SAR) images of waves on Lake Michigan are compared to a wave directional spectrum determined from measurements taken at a tower and to a one-dimensional ...
Variable correlations between Toirano precipitation and hydroclimate in the North Atlantic (Fig.1c; black and blue lines) match the trend of the SLP time series over southwestern England (Fig.1c; brown line) and the reconstructed EA index (Fig.1c; red line)41. This confirms that EA phase...
(3) Vegetation prevents expansion of the blowout in certain directions and impediments to flow, such as slump blocks, alter circulation patterns and sand transport paths. (4) Prevailing onshore winds deflate the floor and promote eastward expansion of lateral erosional lobes, whereas strong flows ...
1a–c). Figure 1a depicts wind rose and the distributions of sand-flux directions. Due to limited sediment supply and unidirectional flows, numerous barchan dunes have formed and migrated at high speed. These highly favorable conditions in the field make it a perfect region for our study. ...

The driving device includes a transmission (16, 17, 18, 20; 51-54) between rings (10, 19) that turns the rings uniformly in mutually opposite directions. The transmission is provided with adjustable setting devices (40, 41; 50) that are arranged in a manner to establish a selected attack...
Ice drift vectors data is stored as two orthogonal vectors, the horizontal and vertical components, ‘u’ and ‘v’.In the EASE-grid projection used for the ice drift, the cardinal directions of ‘u’ and ‘v’ depend on the longitude. References Pyke, G. H., Pulliam, H. R. & ...
(in m/s) is represented by a series of increasing circles starting from the intersection of the two cardinal directions axes where wind speed is null: the farther the circle is away from the intersection, the faster the wind speed is. In panel (B), the density distribution of the average...
