Ionosphere Response to the simultaneous and consecutive occurrence of
Geomagnetic Storm and Lightning at various intensities in a Low Latitude
Region
Abstract
Information from total electron content (TEC) from Global Navigation
Satellite Systems (GNSS) could be assessed to know the impact of weather
events to help in developing prediction and warning systems. The
majority of studies focus on the occurrence of only one event neglecting
situations where these weather events happen almost simultaneously or
consecutively. This current study tends to fill the gap by analyzing
ionosphere response following the simultaneous and/or consecutive
occurrence of geomagnetic storm and lightning events at various
intensities in southern China coastal region. The results showed that
the magnitude of the frequency lightning-related events using continuous
wavelet transform (CWT) was 0.3-0.4 while that of geomagnetic storm was
0.15-0.3. However, the various levels of intensity could not be
distinguished. Being able to differentiate the weather events by the
magnitude values following the ionosphere response is good for
prediction and modeling purposes as the use of TEC in some studies does
not provide this clear distinction.
