co-rotating interaction region.
The difference is expected because this example was taken during the recovery phase of a storm driven by a co-rotating interaction region (CIR) in the solar wind.
Each of them and their associated co-rotating interaction regions (CIRs) caused a series of geomagnetic disturbances, whose effects in geomagnetic indices are shown in Fig. 3 a, b.
High speed solar wind streams also act as a significant driver of activity in the Earth's magnetosphere co-rotating interaction region and are responsible for geomagnetic activities.
Solar wind disturbances, in particular, the co-rotating interaction regions (CIRs) on the leading edge of high-speed streams (HSSs) and interplanetary coronal mass ejections (ICMEs) have been closely linked with the occurrence of scintillation at high latitudes (Prikryl et al. 2012).
Many in-situ spacecraft observations suggest that shock waves in the interplanetary space such as planetary bow shocks and traveling shocks in the co-rotating interaction regions are often accompanied by turbulent fluctuations, and furthermore, there are indications that interstellar shocks or supernova remnants may be associated with turbulence (Hester et al., 1994; Spitler and Spangler, 2005).
High-speed imaging from the downstream side of the combustor demonstrates that the heat release rate perturbation associated with the nonlinear interaction of the helical mode and the acoustic oscillations produces a "yin and yang" -type pattern rotating with the interaction frequency in the direction of the mean swirl.
In the viewing screen (Fig. 8 a), both the reference and test meshes were shown in animation and the interaction (rotating and zooming) was simultaneous.
Co-rotating interaction regions (CIRs) are radially aligned solar wind flows of varying speeds with forward and reverse shocks bordering the flows with greater velocities (Gosling and Pizzo 1999).
The solar wind variability caused by the presence of low-latitude coronal holes on the Sun was also studied and comparisons were made between magnetospheric responses due to CME and co-rotating interaction region (CIR) structures.
During solar minimum, the interaction of co-rotating interaction regions (CIRs) of solar origin with the magnetosphere produces weak recurrent storms (e.g., Richardson et al. 2001; Tulasiram et al. 2010; Cramer et al. 2013).
