This project will examine transient events in the dayside region of Earth's magnetosphere and ionosphere. The study will make use of remote sensing and ground-based data combined with magnetohydrodynamic (MHD) simulations to assess the roles of a variety of physical processes. In particular, the project will examine the properties of waves on the magnetopause boundary to determine the direction in which the waves propagate and the occurrence patterns. Such waves can be generated by pressure pulses in the solar wind, by intermittent magnetic reconnection, or by instabilities such as the Kelvin-Helmholtz instability. The project will also examine how the transient events on the magnetopause propagate down into the ionosphere and lead to transient phenomena in the auroral zones. Most of the research will be carried out by students at the Inter-American University of Puerto Rico San Juan. The project will aid in the development of an graduate level degree program focusing on space and aerospace. It will promote collaborations with the aerospace industry.

该项目将研究地球磁层和电离层白天区域的瞬态事件。 该研究将利用遥感和地面数据与磁流体动力学（MHD）模拟相结合来评估各种物理过程的作用。 特别是，该项目将检查磁层顶边界上波的特性，以确定波传播的方向和发生模式。 这种波可以由太阳风中的压力脉冲、间歇性磁重联或开尔文-亥姆霍兹不稳定性等不稳定性产生。 该项目还将研究磁层顶上的瞬变事件如何传播到电离层并导致极光区的瞬变现象。 大部分研究将由波多黎各圣胡安美洲大学的学生进行。 该项目将有助于开发专注于太空和航空航天的研究生学位课程。 它将促进与航空航天业的合作。
