Abstract: A formula is presented for the frequency distribution function of wind direction, P(?), having a lateral intensity of turbulence, σv/?. A simple set-up is described which measures the relative frequency of electrical dc ...

Abstract: The discontinuity of the wind direction at 360° complicates automatic calculations of some atmospheric parameters. Various methods were suggested to obtain the standard deviation of the wind direction (σ?). They are reviewed ...

Abstract: The variations of lateral gustiness with wind speed were studied using a light-weight, fast-response wind system coupled to an automatic sampling system. Accuracies of 1° in determining the width of the wind direction ...

Abstract: The average flow over northern Israel in July has been analyzed. Three-hourly maps of the flow were obtained and discussed. The synoptic pressure distribution is relatively invariable in this period. Therefore, the flow ...

Abstract: This paper describes an effort to identify instrumental and flow-related contributions to the mean vertical velocity offsets observed by sonic anemometers on the Boulder Atmospheric Observatory's 300 m tower. A simple ...
