Analysis of geomagnetic data identifies significant correlations and dynamics during magnetic storms in Georgia, indicating the importance of localized studies.
Key Points
This research aims to analyze geomagnetic field measurements during intense storms to understand the relationship between various solar and geomagnetic parameters.
Analyzed geomagnetic measurements from Dusheti Observatory during three storms in 2024.
Used cross-correlation, wavelet coherence, and detrended fluctuation analysis to assess data relationships.
Investigated dynamics between interplanetary magnetic field, solar wind plasma, and geomagnetic field H-component.
Identified significant correlations with distinct time lags of approximately 200 minutes.
Revealed complex solar wind-magnetosphere coupling dynamics through wavelet coherence analysis.
Observed increased coherence in plasma with a 12.5-hour time shift, linked to coronal mass ejection structure.
