WebThe development of the turbulence intensity of the same flight still shows an increase at a distance of x=2 D, indicating measurements within the near wake, since the downstream position of the turbulence intensity peak is associated with the transition from the near wake into the far wake (Wu and Porté-Agel, 2012). Webmicroburst turbulence intensity is found in terms of the radial distance from the microburst center and the height above the ground. Based on these turbulence parameters relevant to a microburst, a turbulence model is developed to supplement the existing JAWS quasi-steady mean wind data.
