| Resumo | Changes in the solar wind flow, generally linked to interplanetary coronal mass ejections (ICME) or high-speed streams (HSS), are directly related to the space environment near Earth. The impact of these structures on the Earths magnetosphere perturbs the geomagnetic field. Variable geomagnetic fields give rise to measurable effects in the magnetosphere, the ionosphere, the upper atmosphere, and on the ground. Rapid changes in the geomagnetic field can lead to the generation of geomagnetically induced currents (GICs). Intense GICs can have adverse effects on technology systems, leading to power outages and damage to power grid components as well as impacting pipelines and train systems. The goal of this work is to evaluate how the characteristics of different solar wind structures (ICME and HSS) correlate with the magnetic field perturbation (dB/dt) occurrence, intensity, and location. We selected storm events based on the Sym-H index less than or equal to -50 nT. A total of 534 events were selected, 263 related to ICME and 271 to HSS. To capture the variations in a broad range of latitudes, the thresholds of dB/dt were defined as 200, 300, 400, and 500 nT/min in stations at geographic latitudes varying from +- 30 to +-90 degrees. The asymmetry in the distribution of dB/dt spikes according to MLT, discussed in previous work, is observed. We also observe differences in the preferential location of dB/dt with respect to storms related to HSS and ICME. Our investigation seeks to evaluate the relationship between ground level dB/dt variation and solar wind parameters including mesoscale structures of solar wind events and the periodicity of solar wind velocity and magnetic field variations. This analysis will enhance our understanding of these mechanisms and aid in the incorporation of solar wind parameters to machine learning models to improve the accuracy of forecasts of dB/dt recorded on the ground. | |||
