Simulation of Energetic Particle Precipitation Effects During the 2003-2004 Arctic Winter
Energetic particle precipitation (EPP) during the 2003–2004 Arctic winter led to the production and subsequent transport of reactive odd nitrogen (NOx =NO+NO2) from the mesosphere and lower thermosphere (MLT) into the stratosphere. This caused NOx enhancements in the polar upper stratosphere in April 2004 that were unprecedented in the satellite record. Simulations of the 2003–2004 Arctic winte...
متن کاملThe response of the middle atmosphere to energetic particle precipitation
Accurate representation of odd-nitrogen species (NOx) in the winter polar middle atmosphere is an important factor in correctly predicting ozone in the upper stratosphere. The concentration of NOx depends on several factors, including the state of stratospheric winds, the strength of diffusive transport near the mesopause, and the deposition of energetic particles in the mesosphere and the lowe...
متن کاملEnergetic electron precipitation during sawtooth injections
We present simultaneous riometer observations of cosmic noise absorption in the nightside and dawn-noon sectors during sawtooth particle injections during 18 April 2002. Energetic electron precipitation (>30 keV) is a feature of magnetospheric substorms and cosmic radio noise absorption acts as a proxy for qualitatively measuring this precipitation. This event provides an opportunity to compare...
متن کاملSimulation of denitrification and ozone loss for the Arctic winter
We present simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS) for the Arctic winter 2002/2003. We integrated a Lagrangian denitrification scheme into the three-dimensional version of CLaMS that calculates the growth and sedimentation of nitric acid trihydrate (NAT) particles along individual particle trajectories. From those, we derive the HNO3 downward flux resulting fr...
متن کاملParticle simulation of energetic particle driven Alfv19 en modes
The mutual nonlinear interactions of shear Alfvén modes and alpha particles can enhance their transport in burning plasmas. Theoretical and numerical works have shown that rapid transport of energetic ions can take place because of fast growing Alfvén modes (e.g. energetic particle driven modes, EPMs). This kind of transport has been observed in experiments as well as in numerical simulations. ...
