Notice the three white oval-shaped storms that lie below and left of Jupiter's Great Red Spot. The outer two of the white storms formed in the late 1930s. In the centers of these storms the air is rising, carrying fresh ammonia gas upward. New, white ice crystals form when the upwelling gas freezes as it reaches the chilly cloud top level, where temperatures are -130 degrees C. Other areas are low pressure; the stronger the down flow, the less ice, and the browner the region.
