Practical Calculation Method of Downburst Wind Profiles for Engineering Applications

Abstract:

Downburst is a kind of strong wind that resulted from the flow downdraft in thunderstorm, which could assert the most serious destruction in the zone nearby ground. Researches on downburst usually focusing on modeling and calculations of downburst wind profiles while the proposed nondimensional empirical models are dispersed for practical engineering applications. Accounting for this problem, diagram for of downburst wind profile calculation is cleared up by assuming jet impinging orthogonally and axisymmetrically to plane ground. Different empirical models, which include maximum horizontal velocity distributions at different radial locations, height distribution of half maximum horizontal velocity along radial direction, and horizontal velocity distributions at different heights with constant radial location, are presented and combined together to calculate dimensional radial wind profiles of horizontal velocity. The obtained wind profiles can be combined with atmosphere boundary layer wind profiles together for practical engineering applications.
