Description
Earth’s magnetosheath is a turbulent region where magnetosheath jets, localized dynamic pressure enhancements, are often observed. These magnetosheath jets form primarily at the quasi-parallel bow shock and move through the magnetosheath towards the magnetopause. Jets therefore transport mass, momentum, and energy across the magnetosheath. However, so far there are no estimates on the contribution of jets in energy transport through the magnetosheath due to limitations of observations that are single point measurements. 3D simulations with realistic scales are therefore needed to estimate the contribution of jets to magnetosheath transport. For these estimates we make use of the Amitis code, a hybrid-kinetic plasma simulation (particle ions and fluid electrons). Amitis simulates the solar wind interaction with Earth at realistic scales in three-dimensions in both configuration and velocity space. Using the simulation results we identify the magnetosheath and jets. We then calculate the mass, momentum, and energy contained in jets and compare it to regions deficit of jets. We also calculate the mass and energy flux carried by jets across the bow shock and the magnetopause.
