TL;DR: In this paper, the authors categorize HCS crossings in two ways: first, using the change in magnetic polarity, as either away-to-toward (AT) or toward-toaway (TA) magnetic field directions relative to the Sun, and, secondly using the strength of the associated solar wind compression, determined from the observed plasma density enhancement.

TL;DR: The average error in predicting arrival speed is 151 km s−1, with an average arrival speed of 425km s− 1, and the average transit time of 82.3 h as discussed by the authors.

TL;DR: In this paper, a two-step mechanism is proposed: lightning rates vary with galactic cosmic ray (GCR) flux incident on Earth, either via changes in atmospheric conductivity and/or direct triggering of lightning.

TL;DR: In this article, the authors used the reconstruction of power input to the magnetosphere given in Paper 1 (arXiv:1708.04904) to reconstruct annual means of geomagnetic indices over the past 400 years to within a 1-sigma error of +/- 20pc.

TL;DR: In this article, the authors used a computationally efficient solar wind model to produce 200-member ensemble hindcasts, perturbing the modelled CME parameters within uniform distributions about the best estimates.
