描述了一种降水指数，它基于沿单个卫星轨道所做的观测来量化高纬度粒子降水的强度和空间范围。通过根据该指数对等离子体对流数据进行分类，从由米尔斯通山雷达五年观测所组成的数据集中推导出了电离层对流电场的平均模式。参考瞬时降水指数以及与之对应的平均模式，为描述整个事件中的全球降水和对流模式提供了一种方法。
A precipitation index is described which quantifies the intensity and spatial extent of high-latitude particle precipitation based on observations made along individual satellite passes. By sorting plasma convection data according to this index, average patterns of the ionospheric convection electric field have been derived from a data set consisting of five years' observations by the Millstone Hill radar. Reference to the instantaneous precipitation index, and the average patterns keyed to it, provides a means of characterizing the global precipitation and convection patterns throughout an event.
