近日，美国斯坦福大学Qing Ji团队报道了飓风登陆过程中湍流产生的地震声印记。2026年8月6日，《科学》杂志发表了这一成果。

飓风演变受飓风边界层（HBL）湍流的影响，通常通过飞机观测和塔站测量获取。

通过对一次登陆飓风的案例研究，研究组表明地震声学数据也可用于HBL湍流分析。他们确定了HBL湍流在次声压力和地震位移中的贡献，并通过将基于气象数据校准的大涡模拟与准静态弹性变形建模相结合，验证了该解释。

湍流压力场的对流速度是这种压力-位移耦合的关键。在大气研究领域，连续次声压力可作为10米高度风速的替代观测指标，而压力谱的惯性子区间可估算近地面层顶部（约100至200米高度）的湍流耗散率，与约10米高度的便携式塔站数据形成互补。

Abstract: Hurricane evolution is affected by turbulence in the hurricane boundary layer (HBL), which is typically measured using aircraft flights and towers. Through a case study of a landfalling hurricane, we show that seismoacoustic data can also be used for HBL turbulence analysis. We identified contributions of HBL turbulence in infrasound pressure and seismic displacement, validating our interpretation by combining large-eddy simulation, calibrated with meteorological data, with quasi-static elastic deformation modeling. The convection velocity of the turbulent pressure field is key to this pressure–displacement coupling. For atmospheric studies, continuous infrasound pressure serves as a proxy for 10-meter wind speed, and the inertial subrange of pressure spectra provides an estimate of the turbulent dissipation rate near the top of the surface layer at ~100 to 200 meters, complementing portable tower data at ~10 meters.
