Expansion Speed of Coronal Mass Ejections

Solar Physics, 2009
A large set of limb coronal mass ejections (CMEs) are used to determine the accurate relationship between radial (V rad) and expansion (V exp) speeds of CMEs. It is demonstrated that this relation is exceptionally well described by the function f(w)=1/2(1+cot w), representing a full cone model for the CME

Statistical Characteristics of Stormtime Bursty Bulk Flows

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Bursty bulk flows (BBFs) play a significant role in transporting plasma earthward in the magnetotail. While their properties have been extensively studied, their behavior during geomagnetic storms needs further understanding. In this study, we investigate the stormtime characteristics of BBFs, and compare them to non‐stormtime, by performing a

A Deep Learning Method for Automatic Coronal Mass Ejection Feature Identification

The Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs), intense solar eruptive phenomena, are the primary drivers of extreme space weather storms on Earth. As space activities become increasingly frequent and infrastructure more reliant on space-based systems, the rapid and ...

Regarding the detectability and measurement of coronal mass ejections

Journal of Space Weather and Space Climate, 2015
In this review I discuss the problems associated with the detection and measurement of coronal mass ejections (CMEs). CMEs are important phenomena both scientifically, as they play a crucial role in the evolution of the solar corona, and technologically,

Propagation of an Earth-directed coronal mass ejection in three dimensions

, 2010
Solar coronal mass ejections (CMEs) are the most significant drivers of adverse space weather at Earth, but the physics governing their propagation through the heliosphere is not well understood.

Dawn‐Side Anomaly in Sudden Geomagnetic Field Responses to Solar Wind Pressure Discontinuities During the 10 May and 10 October 2024 Geomagnetic Storms

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Interactions of solar wind dynamic pressure (SWDP) discontinuities with Earth's magnetosphere cause geomagnetic Sudden Commencements (SCs). Typically, positive/negative SCs occur at low latitudes due to enhancements/reductions in SWDP.

Coronal Mass Ejections: Models and Their Observational Basis

Living Reviews in Solar Physics, 2011
Coronal mass ejections (CMEs) are the largest-scale eruptive phenomenon in the solar system, expanding from active region-sized nonpotential magnetic structure to a much larger size.
