|Num=1
|Meaning=(Abbreviated CIR.)
|Explanation=A term used in space weather to denote a compression region ahead of a [[coronal hole]] high-speed stream (CH HSS). They form due to the interaction of slower, ambient [[solar wind]] ahead of the higher-speed stream. They are not associated with every CH HSS; however, they most often develop ahead of the more persistent coronal holes. They usually result in particle [[density]] enhancement and interplanetary magnetic field strength increases and can cause [[geomagnetic storm|geomagnetic storms]] when reaching Earth.
