摘要 介绍并讨论了湖泊效应暴风雪期间密歇根湖顺风岸附近粒子测量系统探测器测量的原位雪粒径谱。冰水含量范围为 0.002 至 0.264 g m−3。尺寸大于1毫米的浓度一般呈指数分布；然而，较小颗粒的浓度通常大于尺寸大于 1 毫米浓度的指数拟合值。指数分布参数（N0 和 λ）与之前报告的值一致。有证据表明在-25°C 时存在颗粒聚集。
Abstract In situ snow particle size spectra measured by Particle Measuring Systems probes near the downwind shore of Lake Michigan during lake-effect snow storms are presented and discussed. Ice water contents ranged from 0.002 to 0.264 g m−3. Concentrations of sizes larger than 1 mm were generally exponentially distributed; however, concentrations of smaller particles usually were greater than suggested by the exponential fitted to concentrations of sizes larger than 1 mm. Exponential distribution parameters (N0 and λ) are consistent with previously reported values. There is evidence of particle aggregation at −25°C.
