Is Solar Wind Turbulence a Driver of Geomagnetic Activity at Mid-Low Latitudes?
Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2014, Vol 9, Issue 2
Abstract
The coupling of solar wind to the magnetosphere is one of the widely studied dynamical processes that characterize the Sun-Earth coupled system. In this work, the effects of solar wind magnetohydrodynamic (MHD) turbulence on geomagnetic field at the mid-low latitudes during the year 2009 when the Sun nearly plunged into the Maunder minimum was studied statistically. We characterized the MHD Alfvénic turbulence by means of 2-D histograms and related these histograms to the behaviour of geomagnetic activity at mid-low latitudes as measured by ASY-D, ASY-H, SYM-D, and SYM-H indices. We discovered that geomagnetic activity at mid-low latitudes is not driven by solar wind Alfvénic turbulence during period of low solar activity.
