对于半径在0.176 ~ 6.61µm之间的颗粒，在80%的相对湿度下，得到了海浪粗糙度雷诺数RHa和RHw的参数化海雾气溶胶源通量。这些源函数在观测中所占的方差是风速本身的两倍。这是第一次直接证明波浪状态对海洋喷雾气溶胶产生变异性的影响。全球欧洲中期天气预报中心业务模式场用于驱动参数化。RH参数化得到的源通量是风速参数化得到的源通量的大约0.1至3倍（RHa）和5倍（RHw），这是由相同的测量得到的，其中波状态与当地风速下的平衡波状态相比，分别是明显不发达或过度发达的。
Parameterizations of the sea spray aerosol source flux are derived as functions of wave roughness Reynolds numbers, RHa and RHw, for particles with radii between 0.176 and 6.61 µm at 80% relative humidity. These source functions account for up to twice the variance in the observations than does wind speed alone. This is the first such direct demonstration of the impact of wave state on the variability of sea spray aerosol production. Global European Centre for Medium‐Range Weather Forecasts operational mode fields are used to drive the parameterizations. The source flux from the RH parameterizations varies from approximately 0.1 to 3 (RHa) and 5 (RHw) times that from a wind speed parameterization, derived from the same measurements, where the wave state is substantially underdeveloped or overdeveloped, respectively, compared to the equilibrium wave state at the local wind speed.
