Cai and Clauer [2009] shows the mean period of sawtooth events has a large variability from 2 to 4 hours, with a mean period around 3 hours. What controls the period, whether by solar wind drivers or internal magnetospheric parameters, is unknown. In this presentation, we examine the relationship between the solar wind drivers and the period for each individual tooth. No clear linear trends are found so we conclude that the period of sawtooth events does not depend on any single solar wind driver exclusively. However sawtooth events driven by stream interaction events have a longer period (~ 180 minutes) than those driven by interplanetary coronal mass ejections (~ 150 minutes). This might suggest the solar wind-magnetosphere system has different coupling efficiencies during these two types of sawtooth events. We also propose an idea to explain why sawtooth events occur periodically and why the Earth has different response modes.
