Abstract

In this paper, we investigate the emissions of Magneto hydrodynamic (MHD) waves along Bursty Bulk Flows (BBFs) located in the Earth's magnetotail. We use the global MHD code LFM coupled with RCM with real-time solar wind data from OMNI as the driver. In chosen substorm events, we look for MHD wave emissions along BBFs, including several hours before and after the substorm onsets and recovery phases, in order to see the effects of solar wind conditions. We look into every phase of a substorm for any generation of MHD waves along BBFs and their relation to substorm phases and solar wind conditions. We then consider the possible evolution of Kelvin-Helmholtz Instability (KHI) along BBFs with MHD waves in order to investigate if the KHI is the driving mechanism for these waves. We further investigate the characteristics of the emitted MHD waves and their possible impacts on the BBFs and the regions surrounding BBFs.
