Abstract Association of coronal holes with large scale solar magnetic fields has been investigated. It is concluded that coronal holes always form in the large unipolar magnetic field patterns, and no specific polarity rule holds true for low-latitude coronal holes. The coronal holes show a strong tendency to bypass the opposite polarity regions in their location. Coronal holes get fragmented into pieces, if opposite polarity flux encroaches and/or erupts into their boundaries. Migration of coronal holes or their fragments and the growth of coronal holes out of hole fragments are also discussed.
