Field Observations of Near-Surface Wind Flow Across Expressway Embankment on the Qinghai–Tibet Plateau

Yanhu Mu,Wei Ma,Zhaohui Joey Yang,Xiaolin Li,Kun Zhang,Yuncheng Mao,

Engineering 2022, Volume 14, Issue 7,   Pages 169-180 doi: 10.1016/j.eng.2021.10.020

Abstract: As convection is a crucial working mechanism of these ACSs, it is imperative to understand the near-surfacewind flow (NSWF) across a constructed infrastructure, such as an embankment.The wind speed and direction along a transect perpendicular to the embankment on both the windward andleeward sides and at four different heights above the ground surface were collected and analyzed.It is concluded that underestimating the PLI and neglecting wind direction variations may lead to unconservative
