WebSep 22, 2016 · According to the statistics of radar measurements, micro-downburst has the scale space range of 1830 m to 3660 m from the strongest headwind to the strongest tailwind, so the horizontal distribution range of vortex pair is set to 5 km. Moreover, the spatial scale of wind shear and the aircraft speed determine the time scale of aircraft … WebThis often appears as a small blue circle within a larger red area.

WebJun 18, 2024 · 1 Introduction. A microburst is a strong downdraft in the lower troposphere, generated by dynamic and thermodynamic effects in the midtroposphere, which produces a divergent pattern of surface wind with a differential speed of, at least, 20 m s −1 (Fujita, 1985; Fujita & Byers, 1977; Fujita & Wakimoto, 1981; Wakimoto, 1985).This surface wind … WebDownbursts are particularly strong downdrafts from thunderstorms.
