Over five decades the large scale properties of the solar wind have been described. These observations have shown that the solar wind flow is turbulent. This research project will refine the description of the solar wind by separating the ordered and disordered structures in the solar wind. The proposal posits that hypothesis that space weather is strongly influenced by the cumulative effects of many small disturbances. The researchers are interested in learning if the properties of the turbulent flows in the solar wind are biased by the presence of small scale "fossil" structures whose source is the Sun. The team has proposed to develop and use a series of analysis techniques not currently used in space physics.This research will support graduate students including training them to use the new techniques. The characterization of the solar wind will be useful for others in studying space weather at Earth.

在五十年的时间里，已经描述了太阳风的大规模特性。这些观察结果表明太阳风流是湍流。该研究项目将通过将太阳风中的有序结构分开，从而完善对太阳风的描述。该提议表明，假设太空天气受到许多小型干扰的累积影响的强烈影响。研究人员有兴趣了解太阳风中湍流的特性是否受到小规模“化石”结构的存在的偏见。该团队已提出开发和使用当前在太空物理中未使用的一系列分析技术。这项研究将支持研究生，包括培训他们使用新技术。太阳风的特征将对其他人在研究地球的太空天气中有用。
