abstract = "{During a geomagnetic storm, the energy deposition from magnetosphere to
thermosphere through Joule heating leads to variations in the
total mass density of thermosphere. In this study, measurements
obtained from the Challenging Minisatellite Payload and Gravity
Recovery and Climate Experiment satellites between 2002 and 2008
are used to study the response of thermospheric density during
geomagnetic storms of different magnitudes inferred from the Dst
index. Based on the height-integrated Joule heating with data
derived from the Defense Meteorological Satellite Program
spacecraft, we statistically analyze 265 geomagnetic storm cases
to study the characteristics of Joule heating distribution and
its influence on thermospheric density. The results show that
between thermospheric density and Joule heating during weak and
moderate geomagnetic storms, the time lag is only about 0-2 hr,
while the same for intense storms is 3-5 hr. This indicates that
the time lag is positively correlated with the intensity of
geomagnetic storms. Besides, it is found that the peak duration
of Joule heating increases for more intense geomagnetic storms.}",
