Space Weather: Characteristics and Dynamics of CME Induced Radio Emissions

研究人员正在使用可视化和跟踪技术来研究从尤利西斯号和风号航天器上远程观测到的行星际II型射电暴。II型辐射是由日冕物质抛射驱动的激波通过行星际介质从太阳传播到地球时产生的，它为日地联系提供了一个中间环节。研究人员将更好地了解(1)单个II型射电暴的物理特征和动力学，(2)II型辐射与日冕物质抛射驱动的冲击和行星际介质条件的关系，(3)射电发射日冕物质抛射的地磁响应特征，以及(4)日冕物质抛射的行星际传输及其到达地球的预测。

The investigators are using visualization and tracking techniques in studying interplanetary type II radio bursts observed remotely from the Ulysses and WIND spacecraft. Type II emissions are generated when coronal mass ejection-driven shocks propagate through the interplanetary medium from sun to Earth, and provide an intermediate link in the solar-terrestrial connection. The investigators will better understand (1) the physical characteristics and dynamics of individual type II radio bursts, (2) the relationship of type II radiation to the coronal mass ejection-driven shocks and conditions in the interplanetary medium, (3) the characterization of the geomagnetic response to radio emitting coronal mass ejections, and (4) the interplanetary transport of coronal mass ejections, and predictions of their arrival at Earth.
