Abstract [en]

The drift of persistent meteor train from the 2009 Leonid shower is studied. A Matlab simulation is performed using cardinal wind data from the National Institute of Polar Research (NIPR) meteor radar in Tromsø. The simulation is compared with NIPR all-sky images of the train to see if the wind velocity can explain its drift. The lower altitude part of the simulated train correlates decently with the images in both northward and eastward directions. The higher altitude part of the simulation have the correct northward movement but moves with high speed to the east while the all-sky images indicate a fast westward movement. This discrepancy can likely be attributed to the ~200 km2  averaging of the wind field by the meteor radar and turbulence in the atmosphere.
