NARRATOR: Leeward ("south") of a godwall ("baffle")...
MURTAUGH: Doesn't the lee side of a mountain typically get less rain than the windward side?
LEGS: Yes, but mere mountains aren't big enough to create a permanent low-pressure zone.
Lower pressure cools the air and lowers the dewpoint. That means more clouds and more rain.
SCHLOCK: And more sea-monsters.
