Abstract:
Stratospheric warming is related to the strong planetary wave activities in the polar region. In recent years, observations have shown noticeable ionospheric signatures in the mid and lower latitudes during stratospheric warming events. In this report, we present mid latitude lower and upper thermospheric wind observations from Boulder and Millstone Hill Fabry Perot interferometers and incoherent scatter radar ionosphere observations from Millstone Hill during the Jan 2013 stratospheric warming event. We also compare the observation with various simulations from TIEGCM, TIMEGCM, and WACCM to examine the stratospheric influence and geomagnetic effects on the mid latitude thermospheric winds and ionosphere density.
