| Summary: | Geomagnetic storm is a large-scale disturbances in the Earth's magnetic field that
serve as representations of space weather. Various efforts have been made to
prevent and reduce the impact of geomagnetic storms caused by extreme space
weather, one of which is to predict the scale of disturbances that will occur on Earth.
Geomagnetic storm prediction requires sufficient realtime observation data as an
input provider and a numerical model that can project current conditions into the
future as the main element. Various geomagnetic storm models have been
proposed. One of the geomagnetic storm models that is constantly undergoing
development is WINDMI, which is a model of low-dimensional solar wind energy
transfer through the magnetosphere to the ionosphere. This model is able to predict
the intensity of geomagnetic storms by producing a geomagnetic disturbance index
in the form of AL and Dst. This Final Project discusses the prediction of weak (Dst
<-50 nT), medium (Dst <-100 nT), and strong (Dst <-200 nT) storm models in the
24th solar cycle that best fits the observations based on the WINDMI model. The
cause of each geomagnetic storm originating from solar eruptive phenomena is
determined by means of solar wind plasma parameters and interplanetary magnetic
fields using descriptive analysis. |
