DIURNAL AND SEMIDIURNAL ATMOSPHERIC TIDES IN RELATION TO PRECIPITATION VARIATIONS1

Abstract

Evidence is presented that precipitation variations in the United States are related to the solar and lunar tidal forces. The results of the statistical investigation are consistent with a mathematical model that shows how a small periodic influence can be of possible importance for the timing of an event such as the initiation of precipitation.
