结合太阳轨道器上的METIS日冕仪对日冕源区的遥感观测，研究了帕克太阳探测器在日球层最内层的太阳风。2021-01-17 UT时间16：30，METIS观测到的黄道面附近日冕流出的区域位于太阳边缘上方3.5R⊙和6.3RAu之间，这可能与PSP在太阳0.11Au和0.26Au采样的流有关，时间间隔几乎为5天。这两个等离子体流来自两个不同的源区，在日冕底部具有不同的磁场极性和强度。因此，这两个流的全局和局部属性都是不同的。具体地说，从较强磁场区域发出的太阳风，正如预期的那样，具有较低的体积通量密度，并且处于阿尔夫尼克湍流发育良好的状态，具有低间歇性。在几乎不可压缩的磁流体力学背景下，这可以用板条湍流来解释。相反，来自较弱磁场区域的太阳风的高度间歇性和欠发达的湍流行为可能是由于大的磁偏转，最可能归因于互换重新连接起源的回转的存在。
The solar wind measured in situ by Parker Solar Probe in the very inner heliosphere is studied in combination with the remote-sensing observation of the coronal source region provided by the METIS coronagraph aboard Solar Orbiter. The coronal outflows observed near the ecliptic by Metis on 2021 January 17 at 16:30 UT, between 3.5 and 6.3 R ⊙ above the eastern solar limb, can be associated with the streams sampled by PSP at 0.11 and 0.26 au from the Sun, in two time intervals almost 5 days apart. The two plasma flows come from two distinct source regions, characterized by different magnetic field polarity and intensity at the coronal base. It follows that both the global and local properties of the two streams are different. Specifically, the solar wind emanating from the stronger magnetic field region has a lower bulk flux density, as expected, and is in a state of well-developed Alfvénic turbulence, with low intermittency. This is interpreted in terms of slab turbulence in the context of nearly incompressible magnetohydrodynamics. Conversely, the highly intermittent and poorly developed turbulent behavior of the solar wind from the weaker magnetic field region is presumably due to large magnetic deflections most likely attributed to the presence of switchbacks of interchange reconnection origin.
