Wind profile analysis for selected tropical cyclones over the South China Sea based on dropsonde measurements

Abstract

Highlights l Inflow/outflow is determined using dropsonde data and used to explain the strengthening/weakening trend of the typhoons l Vertical wind profiles of the typhoons as revealed by the dropsonde are compared with those in the wind engineering codes for southern China l It is proposed that the wind engineering codes for southern China be modified to take into account more dropsonde measurements over the South China Sea

Dropsonde observations and numerical simulations of intensifying/weakening tropical cyclones over the northern South China Sea

“…As reported in He et al . (2020), there is virtually no inflow of the air according to the vertical wind profiles. The thermodynamic profiles are presented in Figure 8.…”

“…This paper is a follow‐up of the previous case study by He et al . (2020) with the novelty of the consideration of thermodynamic profiles and the case study of the rapidly intensifying Cyclone Higos in 2020.…”

“…A weakening case is shown in Figure 7(c), that of Cyclone Khanun in 2017. As reported in He et al (2020), there is virtually no inflow of the air according to the vertical wind profiles. The thermodynamic profiles are presented in Figure 8.…”

Aircraft observations of Typhoon Nesat (2022) over the northern part of South China Sea

“…Instead, dropsondes provide vital information on the vertical profiles of cyclones, for example as stated in He et al . (2021) regards the strengthening and weakening of TCs, and in Chan et al . (2023) about the structure of a rare cyclone necessitating the issuance of gale to storm warning in Hong Kong during a late season (November) typhoon in this region.…”
