Numerical modeling of solar wind and coronal mass ejection in the inner heliosphere: A review

نویسندگان

چکیده

The predictions of plasma parameters in the interplanetary medium are core space weather forecasts, and magnetohydrodynamics (MHD) numerical simulation is an important tool prediction parameters. Operational forecasts commonly produced by a heliosphere model whose inner boundary set at 18 R s or beyond. Such typically use empirical/physics-based conditions to solve MHD equations for simulation. In recent years, significant progress has been made modeling heliosphere. this paper, solar wind coronal mass ejection reviewed. particular, different used investigated since solutions predetermined treatment large extent. Discussion on further development model.

Radial evolution of solar wind intermittency in the inner heliosphere

We analyzed intermittency in the solar wind, as observed on the ecliptic plane, looking at magnetic field and velocity fluctuations between 0.3 and 1 AU, for both fast and slow wind and for compressive and directional fluctuations. Our analysis focused on the property that probability distribution functions of a fluctuating field affected by intermittency become more and more peaked at smaller ...

Two-step forecast of geomagnetic storm using coronal mass ejection and solar wind condition

To forecast geomagnetic storms, we had examined initially observed parameters of coronal mass ejections (CMEs) and introduced an empirical storm forecast model in a previous study. Now we suggest a two-step forecast considering not only CME parameters observed in the solar vicinity but also solar wind conditions near Earth to improve the forecast capability. We consider the empirical solar wind...

The Solar Wind in the Outer Heliosphere

This paper reviews solar wind observations in the outer heliosphere, concentrating on new developments in the past 3 years. Voyager 2 has detected an increase in speed and decrease in normalized density, consistent with spending more time in the fast polar ow as it moves to higher heliolatitudes. The proton temperatures continue the increase which began at about 35 AU. We describe a new feature...

A Simulation of a Coronal Mass Ejection Propagation and Shock Evolution in the Lower Solar Corona

We present a detailed simulation of the evolution of a moderately slow coronal mass ejection (CME; 800 km s 1 at 5 R , where R is solar radii) in the lower solar corona (2Y5 R ). The configuration of the Sun’s magnetic field is based on the MDI data for the solar surface during Carrington rotation 1922. The pre-CME background solar wind is generated using the Wang-Sheeley-Arge (WSA) model. To i...

Coronal mass ejections and magnetic flux buildup in the heliosphere

[1] To test for magnetic flux buildup in the heliosphere from coronal mass ejections (CMEs), we simulate heliospheric flux as a constant background open flux with a time-varying interplanetary CME (ICME) contribution. As flux carried by ejecta can only contribute to the heliospheric flux budget while it remains closed, the ICME flux opening rate is an important factor. Two separate forms for th...
