Parameter Characterization of High Latitude Geomagnetic Storms in 2010 ()
ABSTRACT
Geomagnetic storm is a kind of
severe disturbance that lasts for more than ten hours to several tens of hours
in the entire Earth’s magnetosphere. This paper uses the NRLMSISE-00 model to
calculate the temperature and density data. According to the surveyed medium
magnetic storm events, the characteristics of daily average density and
temperature in the occurrence of magnetic storms in 2010 were studied. At the
same time, high latitude meridians were taken as research objects. Divide the
temperature and density characteristics at different heights. Results showed
that the annual trend of density is the same for different heights, and there
is an average of the average density every day on the six medium magnetic storm
mountains. For the average daily temperature,
each medium magnetic storm event corresponds to a temperature peak. The
peak temperature on April 5 was the highest temperature throughout the year,
consistent with the annual average density distribution. Due to the intensity
of the magnetic storm, the temperature of a large area of bright areas rose
sharply on April 12, which is also the highest in the year. At 18:00 on May 2,
it was the peak time of the moderate magnetic storm event caused by CIR, but
May 3 was the date of the peak temperature. This peak delay is reasonable.
