Space Weather: Using L1 Observations to Predict Solar Wind Conditions at Earth

研究人员将描述在内拉格朗日点（L1）（距离地球约160万公里）观测到的太阳风条件与30-60分钟后“相同”等离子体到达地球时的条件之间的差异。 该方法是扩展以前的工作，其中他们开发了经验关系的概率，太阳风事件在L1以类似的形式出现在地球上。新的努力是结合磁场数据，以确定磁场条件是否影响等离子体相关性。

The investigators will characterize differences between solar wind conditions observed at the inner Lagrange point (L1), approximately 1.6 million kilometers sunward of the Earth and the conditions at Earth 30-60 minutes later when the "same" plasma arrives. The approach is to expand on previous work in which they developed empirical relations for the probability that solar wind events at L1 appear in a similar form at Earth. The new effort is to incorporate magnetic field data to determine whether magnetic field conditions affect plasma correlations.
