Project Summary Greenwald/ATM-9320146 This project will evaluate the range of physical processes leading to the transfer of energy, momentum and mass from the solar wind to the earth's upper atmosphere. Specifically, the investigators will identify the conditions in the solar wind and earth's magnetosphere that lead to the onset of current surges and then to track the resulting gravity waves in the upper atmosphere as they propagate equatorwards, dissipating their energy. The proposal will constitute a continuation of a previous three-year study using high-latitude ground-based and satellite instrumentation for studies of gravity waves launched by electrojet current surges.

Greenwald/ATM-9320146项目摘要 该项目将评估导致能量、动量和质量从太阳风转移到地球高层大气的各种物理过程。 具体来说，研究人员将确定太阳风和地球磁层中导致电流浪涌发生的条件，然后跟踪高层大气中产生的重力波，因为它们向赤道传播，耗散它们的能量。 该提案将是前一项为期三年的研究的继续，该研究利用高纬度地面和卫星仪器研究电射流电流浪涌发射的重力波。
