When the Moon is high in the sky, it produces bulges in the Earth’s atmosphere that create measurable changes in the amount of rain that falls below, according to new research. But no-one should carry an umbrella just because the Moon is rising — even in the tropics, average rainfall rates are only increased by 1/10,000 of an inch per hour.
