Why does Titan, Saturn's largest moon, have what looks like an enormous white arrow about the size of Texas on its surface? A research group has answered this question by using a global circulation model of Titan to demonstrate how planetary-scale atmospheric waves affect the moon's weather patterns, leading to a "stenciling" effect that results in sharp and sometimes surprising cloud shapes.
