Continuous volcanic infrasound signal was recorded on a three-microphone network at Kilauea in July 2008 and inverted for near-surface horizontal winds. Inter-station phase delays, determined by signal cross-correlation, vary by up to 4% and are attributable to variable atmospheric conditions. The results suggest two predominant weather regimes during the study period: (1) 6-9 m/s easterly trade winds and (2) lower-intensity 2-5 m/s mountain breezes from Mauna Loa. The results demonstrate the potential of using infrasound for tracking local averaged meteorological conditions, which has implications for modeling plume dispersal and quantifying gas flux.
2008 年 7 月，基拉韦厄火山上的三麦克风网络记录到连续的火山次声信号，并对近地表水平风进行了反演。通过信号互相关确定的站间相位延迟变化高达 4%，这归因于可变的大气条件。结果表明，在研究期间存在两种主要的天气类型：（1）6-9 m/s 的东风信风；（2）来自莫纳罗亚山的强度较低的 2-5 m/s 的山风。结果表明，利用次声跟踪当地平均气象条件具有潜力，这对模型羽流扩散和定量气体通量具有重要意义。
