摘要：1978 年 12 月 9 日，在湖效应暴风雪期间，利用多普勒雷达和飞机对密歇根湖上空的边界层结构和环流进行了探测。证据表明，观测到的风平行回波带和卫星云带是由边界层水平滚转对流产生的。讨论了辊场内降水的组织，并将辊的几何形状与文献中报道的干水平辊对流的情况进行了比较。
Abstract The boundary-layer structure and circulation over Lake Michigan were probed with a Doppler radar and an aircraft during a lake-effect snow storm on 9 December 1978. Evidence is presented that observed wind-parallel echo bands and satellite cloud bands resulted from horizontal-roll convection in the boundary layer. The organization of precipitation within the roll field is discussed, and the roll geometry is compared with cases of dry horizontal-roll convection reported in the literature.
