On the relation between ionospheric winter anomalies and solar wind
Ionospheric winter anomalies solar wind
2015/9/28
There are two different winter anomalies. A small one that appears in connection with ionization at relatively low latitudes in the bottom of the D-region of the ionosphere. There, the electron densit...

inospheric forecasting ionospheric modelling ionospheric storms
2015/9/10
For the reliable performance of technologically advanced radio communications systems under geomagnetically
disturbed conditions, the forecast and modelling of the ionospheric response during storms ...
Alfvén Waves in the Solar Wind
Alfvé, n wave Solar wind Rotational Discontinuity Tangential Discontinuity Solar wind structures
2013/10/3
Alfvén waves are found to be ubiquitous in the solar wind. Recent progress in observational studies of the waves is reviewed to formulate a microscopic picture for the Alfvénic fluctuations. The main ...
Changes in Sea-Level Pressure over South Korea Associated with High-Speed Solar Wind Events
solar-terrestrial weather sea-10 level pressure solar wind
2011/8/16
Abstract: We explore a possibility that the daily sea-level pressure (SLP) over South Korea responds to the high-speed solar wind event. This is of interest in two aspects: First, if there is a statis...
Apparent temperature anisotropies due to wave activity in the solar wind
Solar wind plasma — Wave–particle interactions—Waves in plasma.
2011/9/8
The fast solar wind is a collisionless plasma permeated by plasma waves on many different scales. A plasma wave represents the natural interplay between the periodic changes of the electromagnetic fie...
The higher order statistics of magnetic field magnitude fluctuations in the fast quiet solar wind are quantified systematically scale-by-scale for the first time. We find a single global non-Gaussian ...

Solar wind low-frequency magnetohydrodynamic turbulence extended self-similarity scaling laws
2009/11/16
In this paper we review some of the work done in investigating the scaling properties of Magnetohydrodynamic turbulence, by using velocity fluctuations measurements performed in the interplanetary spa...

In this paper we establish links between turbulence dissipation and wave-particle interactions in the solar corona and wind. Based on quasilinear theory, a set of anisotropic, multi-component fluid eq...
The study of the interaction of the solar wind with magnetized and unmagnetized planets forms a central topic of space research. Focussing on planetary magnetosheaths, we review some major development...
