Space Weather: Forecasting the State of the Solar Wind

这笔赠款将开发一个太阳风计算模型，能够根据对太阳的远程观测预测太阳风状况。 PI将开发一个全面的三维磁流体动力学（MHD）模型，能够计算太阳风从太阳到地球轨道以外的起源。 基于一个强大的MHD代码已经用于三维计算的日冕和太阳风，该仪器产生了令人满意的计算与日冕和日光层的观测。 代码的主要改进将包括重要的动力学和热力学效应，包括过渡区，辐射，热传导，日冕加热和阿尔芬波加速。 该项目涉及到实施1-D形式主义到一个3-D MHD模型，并参数化的重要影响，通过比较太阳神，风，太阳风数据。 这项资助的最终结果是：一种独特的计算工具，能够预测日冕和日光层内部的演变结构。

This grant will develop a computational model of the solar wind, capable of forecasting solar wind conditions based on remote observations of the Sun. The PI will develop a comprehensive three-dimensional magnetohydrodynamic (MHD) model capable of computing solutions for the solar wind from its genesis at the Sun to beyond Earth orbit. Based on a robust MHD code already used in 3-D calculations of the corona and solar wind, this instrument has produced agreeable calculations with coronal and heliospheric observations. Key improvements to the code will be inclusion of important dynamic and thermodynamic effects, including a transition region, radiation, thermal conduction, coronal heating and Alfven wave acceleration. The project relates to implementing the 1-D formalism into a 3-D MHD model, and parameterizing the important effects via comparison to Helios, WIND, and Ulysses solar wind data. The grant's end result: a unique computational tool capable of predicting the evolving structure of the solar corona and inner heliosphere.
