Query: Bursty magnetic reconnection at the Earth's magnetopause triggered by
  high-speed jets   The impact of high-speed jets -- dynamic pressure enhancements in the
magnetosheath -- on the Earth's magnetopause has been observed to trigger local
magnetic reconnection. We perform a three-dimensional hybrid simulation to
study the magnetosheath and magnetopause under turbulent conditions using a
quasi-radial southward interplanetary magnetic field (IMF). In contrast to
quasi-steady reconnection with a strong southward IMF, we show that after the
impact of a jet on the magnetopause, the magnetopause moves inwards, the
current sheet is compressed and intensified and signatures of local magnetic
reconnection are observed, showing similarities to spacecraft measurements
