متن کاملSolar 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...

متن کاملSolar 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...
متن کاملCross polar cap potentials measured with Super Dual Auroral Radar Network during quasi-steady solar wind and interplanetary magnetic field conditions
[1] We have analyzed Super Dual Auroral Radar Network (SuperDARN) data between February 1998 and December 2000 to determine the statistical characteristics of the total variation in the high-latitude ionospheric electric potential, or cross polar cap potential, PC. Periods are chosen to satisfy the criteria that (1) the solar wind and interplanetary magnetic field (IMF) are quasi-stable for 40 ...
