春季亚洲沙尘暴的气溶胶上升到高海拔地区，平流穿过太平洋，近年来被认为定期到达美国西部。作为我们使用遥感测量的长期卷云研究计划的一部分，我们观察到与亚洲尘埃气溶胶输送相关的异常温暖的卷云冰云。偏振激光雷达的数据表明，尘埃粒子，这是特别活跃的冰核，可以影响云的形成和阶段，从而改变其辐射特性，至少远至美国东部大盆地。
Aerosols lofted to high altitudes by springtime Asian dust storms advect across the Pacific Ocean and, as recognized in recent years, regularly reach the western US. As part of our long‐term cirrus cloud research program using remote sensing measurements, we have observed unusually warm cirrus ice clouds associated with transported Asian dust aerosols. The polarization lidar data presented for illustration here suggest that the dust particles, which are indicated to be especially active ice nuclei, can affect the formation and phase of clouds, and hence alter their radiative properties at least as far away as the eastern Great Basin of the US.
