Mutual Information as a Nonlinear Measure of
Correlation in Multi-point Measurements in the
Solar Wind
By Rob Wicks
With increasing numbers of
spacecraft in the solar wind new
techniques for analysing multispacecraft data are in demand.
We present results obtained
using mutual information to
measure
correlation
of
fluctuations in the magnetic
field, density and velocity of the
solar wind observed by the ACE
and WIND spacecraft. We show
that there is variation in
correlation length with the solar
cycle, this has implications for
research into coronal heating,
solar wind acceleration and
cosmic ray propagation in the
heliosphere.
The postgraduate seminar series is a series of informal talks run by
postgraduates for postgraduates. All postgraduates are welcome and
refreshments are always provided!
