Evolution and Structure of a Dry Microburst Line Observed by Multiple Remote Sensors in a Plateau Airport

The civilian airplane is a common transportation mode for the local people in Qinghai-Tibet Plateau (QTP). Due to profound dynamic and thermal effects, QTP can trigger strong windstorms during warm season, which downbursts cause severe low-level wind shear threaten aviation safety. However, study of over has not been given much attention. This analyzes interprets typical traveling dry microburst line that happened at Xining Caojiapu International Airport (ZLXN) on 14 May 2020, intending show better understanding explore synergetic usage different remote sensing technologies downburst detection warning plateau airports. Specifically, characteristics synoptic conditions, convective system formation process, structure evolution relevant winds are comprehensively investigated. results that, under control an upstream shallow trough, features atmosphere state, including dry-adiabatic stratification, temperature inversion, increases solar radiation heating, vertical shears horizontal winds, be favorable atmospheric prerequisites development storms downbursts. Low-reflectivity storm cells Mesoscale Convective System (MCS) organize form narrow bow echoes, radial convergences rapid descending reflectivity cores with hanging virga as observed by Doppler weather radar. Moreover, details gales, gust fronts, convergences, turbulences, collisions, outflow interactions triggered also detected interpreted scanning lidar from perspectives. In addition, findings this work have compared Denver, U.S., some simulation studies. Finally, few conceptual models evolutions influenced given.
