Summary
We investigated the unidirectional fractional density gradient in GSE-z (GzU) of Galactic Cosmic Ray (GCR) by using the data obtained by the Muon detector network. The analysis period is from 1994 to 2005. We found that the yearly averaged GzU show temporal variations. It was also found that there is a correlation between the North-South asymmetries of GCR density and solar wind speed at high latitudes. These results suggest that there are some physical connections between them.
