| 摘要 | Geomagnetic data from 20 observatories in East-Asia and Oceania regions were used
to investigate the seasonal variation characteristics of the external and internal Sq current systems
by spherical harmonic analysis (SHA). The seasonal current models of D (northern winter) season, E
(equinox) season, and J (northern summer) season have been constructed respectively, and the current
parameters of these models were analyzed. The main results are obtained as follows: (1) The local time
T of the northern vortex moves from local noon to prenoon from D to E to J season for both external and
internal currents; meanwhile, in the southern hemisphere, the T moves from local noon to afternoon.
(2) The vortex intensity J increases from local winter to equinox then to local summer. The interseasonal
change rate of internal current is larger than that of external current. (3) The latitude Φ of the external
current vortex exhibits seasonal variation in the southern hemisphere, while in the northern hemisphere
the latitude Φ of the internal current vortex shows obvious seasonal changes. (4) The correlations between
the internal and external currents are further analyzed. In the E season the correlation of T is the highest,
and in the local summer and winter, the correlation of J is the strongest. The different seasonal behavior
of the external and internal current systems is unexpected, and its mechanism remains to be identified in future study |
