Solar Wind and Interplanetary Magnetic Field: A Tutorial

The convection layer completes the transport of energy from the nuclear furnace at the center of the sun to its radiation into space by the photosphere, but most importantly for the solar wind it sets the temporal and spatial scales for the structure of the coronal magnetic field that in turn controls the properties of the solar wind. In this tutorial review we examine the properties of the fie...

Solar wind and interplanetary magnetic field features before magnetic storm onset

The presented results, concerning the features of the solar wind plasma structure as observed by spacecraft upstream of Earth, could be used for development of middle-term forecasts of magnetic storms. We have analyzed 1-hour data for 1995-2005 and a whole year of 1-min data during solar minimum (1995) and during solar maximum (2000) with 48 and 60 storms, respectively. The long-term statistica...

Reconstruction of Solar Coronal Linear Force-Free Magnetic Field

Investigation of global solar magnetic field by computational topology methods

This paper analyzes the dynamics of large scale or background solar magnetic field by the methods of computational topology. First of all, we investigate global reversal of the field. A reversal refers to a change in the sign of the field dipole component on the solar poles. The synoptic chart is a synthetic representation of solar structures visible during one rotation of the Sun. A time seque...
