The Origin of Major Solar Activity - Collisional Shearing Between Nonconjugated Polarities of Multiple Bipoles Emerging Within Active Regions
Georgios Chintzoglou, Jie Zhang, Mark C. M. Cheung +1
Active Regions (ARs) that exhibit compact Polarity Inversion Lines (PILs) are known to be very flare-productive. However, the physical mechanisms behind this statistical inference…
Torsional Alfven wave embedded ICME magnetic cloud and corresponding geomagnetic storm
Anil N. Raghav, Ankita Kule, Ankush Bhaskar +3
The energy transfer during the interaction of large-scale solar wind structure and the Earth's magnetosphere is the chronic issue in space-weather studies. To understand this, rese…
Definition of the moist-air exergy norm: a comparison with existing "moist energy norms"
Pascal Marquet, Jean-François Mahfouf, Daniel Holdaway
This study presents a new formulation for the norms and scalar products used in tangent linear or adjoint models to determine forecast errors and sensitivity to observations and to…
A Study of a Compound Solar Eruption with Two Consecutive Erupting Magnetic Structures
Suman K. Dhakal, Georgios Chintzoglou, Jie Zhang
We report a study of a compound solar eruption that was associated with two consecutively erupting magnetic structures and correspondingly two distinct peaks, during impulsive phas…
Exponential Integrators with Parallel-in-Time Rational Approximations for the Shallow-Water Equations on the Rotating Sphere
Martin Schreiber, Nathanaël Schaeffer, Richard Loft
High-performance computing trends towards many-core systems are expected to continue over the next decade. As a result, parallel-in-time methods, mathematical formulations which ex…
Dayside magnetospheric and ionospheric responses to a foreshock transient on June 25, 2008: 2. 2-D evolution based on dayside auroral imaging
Boyi Wang, Yukitoshi Nishimura, Heli Hietala +8
The foreshock region involves localized and transient structures such as foreshock cavities and hot flow anomalies due to solar wind-bow shock interactions, and foreshock transient…
