The ambient solar wind plays a significant role in propagating interplanetary coronal mass
ejections and is an important driver of space weather geomagnetic storms. A …

Progress in space weather research and awareness needs community-wide strategies and
procedures to evaluate our modeling assets. Here we present the activities of the Ambient …

Space weather models endeavoring to connect remote observations to in-situ
measurements at various locations in the heliosphere invariably require a coronal model to …

The solar magnetic fields emerging from the photosphere into the chromosphere and corona
are comprised of a combination of closed (field lines with both ends rooted at the Sun) and …

Efforts are underway to use high-precision timing of pulsars in order to detect low-frequency
gravitational waves. A limit to this technique is the timing noise generated by dispersion in …

We explore the use of observed polar coronal holes (CHs) to constrain the flux distribution
within the polar regions of global solar magnetic field maps in the absence of reliable quality …

State-of-the-art predictions of the solar-wind and space weather phenomena are today
largely based on the equations of magnetohydrodynamics (MHD). Despite their …

A potential field solution is widely used to extrapolate the coronal magnetic field above the
Sun's surface to a certain height. This model applies the current-free approximation and …

As an important part of space weather forecasting, the prediction of solar wind parameters in
the near‐Earth space is particularly significant. The introduction of data assimilation (DA) …

The release and acceleration of the solar wind is still an outstanding question. There are
several aspects related to this phenomenon that still need to be investigated, and one of …
