Hurricane gif part 2 (IMAGE)
Caption
Warm, moist air above the Eastern Pacific is less dense than cold, drier air. This difference in density leads to convection and, ultimately, the generation of Rossby waves. Rossby waves create atmospheric circulation changes depicted here as two rotating circles—cyclone in blue and anticyclone in white. Closer to the sea surface, air moves in a clockwise direction. Higher in the atmosphere, air moves counterclockwise.
