We present here a simulation based study of possible sawtooth activity during the magnetic storms during the periods of October 29 to November 1, 2003. Our initial simulation of this period using the Lyon-Fedder-Mobarry (LFM) global MHD code showed indications of sawtooth activity after 1800 of October 29, consistent with observations from geosynchronous orbit. We present here the results of new simulations we have performed to address possible problems of our initial simulation due to uncertainties in the solar wind observations and relatively low spatial resolution used. We have used a synthesis of the ACE and GEOTAIL plasma data, we have using the Lyon-Fedder-Mobarry (LFM) global MHD code to simulate both the magnetosphere and ionosphere, with progressively larger grid resolutions. We also have performed a simulation using the CMIT model, in which the ionosphere of the LFM is replaced by the NCAR Thermosphere Ionosphere Nested Grid (TING). We will investigate closely the plasma and magnetic field configurations in the inner magnetosphere for all the simulations to identify the presence of sawtooth activity. We will compare our results with the available magnetospheric and ionospheric observations, in particular observations from geosynchronous satellites.
