Why is the ninth month called September?

katabatic wind

wind that blows down a slope because of gravity. It occurs at night, when the highlands radiate heat and are cooled. The air in contact with these highlands is thus also cooled, and it becomes denser than the air at the same elevation but away from the slope; it therefore begins to flow downhill. This process is most pronounced in calm air because winds mix the air and prevent cold pockets from forming.
