Connections Between Global Solar Magnetic Field Evolution and Interplanetary Transients

这个项目将把联合收割机威尔科克斯太阳观测站的实地数据和航天器的现场数据或日冕活动结合起来，以审查至少三个与太阳场演变和日冕及行星际现象之间的联系有关的问题。 这些问题包括：（1）源面外通量的太阳周变化与日冕物质抛射及其对应物行星际太阳风热通量下降的发生率之间的关系是什么？ (2)在日冕场模型中看到的日冕场结构演化与日冕物质抛射的位置和特征之间有什么关系？ (3)行星际日冕物质抛射场的出现与其投射源区的日冕场结构有什么关系？ 这些研究的结果将提供利用全球太阳磁场观测的新方法，作为了解和预测行星际瞬态现象的多用途工具。

This project will combine Wilcox Solar Observatory field data and spacecraft in-situ data or coronagraph activities to examine at least three questions related to the connection between evolution of the solar field and coronal and interplanetary phenomena. These questions include: (1) What is the relationship between the solar cycle variation of the flux out of the source surface and the occurrence rates of coronal mass ejections and their opposite counterparts, interplanetary solar wind heat flux dropouts? (2) What is the relationship between the coronal field structure evolution, as seen in the coronal field models, and the locations and characteristics of coronagraph CMEs? (3) What is the relationship between the appearance of interplanetary coronal mass ejection fields and the structure of the coronal fields in their projected source regions? Results of these studies will provide new ways of exploiting global solar magnetic field observations as a multi-purpose tool for understanding and predicting interplanetary transient phenomena.
