The results of eight soundings conducted from sites at high latitude during the summers of 1963 through 1965 suggest that a relation exists between the winds at the mesopause and the occurrence of noctilucent clouds. These measurements indicate that situations in which noctilucent clouds are present are associated with lower wind speeds than is the case where there are no clouds.
