中文摘要:
      海气之间动量和热量交换在台风生成和维系过程中扮演着重要角色。虽然已有研究指出海气通量依赖于表面波和海洋飞沫,但其影响机制仍需要通过现场观测数据进行有效评估。为此,本文利用南海北部浮标观测获取的2008年黑格比台风过境期间的气象和表面波时间序列,研究表面波和海洋飞沫对海气通量的影响。其中,浮标位置非常接近台风,且最小距离不足40公里。研究表明,表面波的存在使海气动量通量增长15%,海洋飞沫的存在使黑格比台风从海洋中多汲取500 W/m2的热通量。这些结果无疑对于理解台风-海洋相互作用、改善台风强度预报技巧具有重要的参考价值。
英文摘要:
      Air-sea exchange plays a vital role in the development and maintenance of tropical cyclones (TCs). Although studies have suggested the dependence of air-sea fluxes on surface waves and sea spray, how these processes modify those fluxes under TC conditions have not been sufficiently investigated based on in-situ observations. Using continuous meteorological and surface wave data from a moored buoy in the northern South China Sea, this study examines the effects of surface waves and sea spray on air-sea fluxes during the passage of Typhoon Hagupit. The mooring was within about 40 km of the center of Hagupit. Surface waves could increase momentum flux to the ocean by about 15%, and sea spray enhanced both sensible and latent heat fluxes to the atmosphere, causing Hagupit to absorb 500 W/m2 more heat flux from the ocean. These results have powerful implications for understanding TC-ocean interaction and improving TC intensity forecasting.
