Özet
A geomagnetic storm is a major disturbance in the Earth's magnetosphere due to the solar wind entering the magnetosphere and ionosphere, lasting about 1-3 days. Storms are known by different categorical names such as weak, moderate, strong (intense), severe (very intense). This study aims to make a mathematical analysis of the latest super geomagnetic storm of the 23rd solar cycle (Dst: -247 nT) which occurred on May 15, 2005. The variables of the study are solar wind parameters (Bz, E, P, N, v, and T) and zonal geomagnetic indices (Dst, ap, and AE). The value range and deviations of variables were defined by the descriptive analysis and the binary relationships of the data were shown by the covariance matrix. A factor analysis was carried out with the help of normal distributions of data and the event (geomagnetic storm) was discussed with linear and nonlinear models. Finally, nonlinear model is also created with solar wind pressure (P), proton density (N), and the ap index. This model explains the storm with an accuracy of 87.5%. In general, this study aims to help the reader understand the storm by presenting models in which parameters and inscription coexist.
