How do the seasons on Uranus work when the planet is tilted so far?

Because Uranus is tipped almost on its side, the sunlight it receives changes dramatically over the course of its orbit. Each pole can face the Sun for decades, then spend decades in darkness, creating extraordinary seasonal swings. Since Uranus takes about 84 Earth years to orbit the Sun, one pole experiences roughly 42 years of daylight before the situation reverses. The atmosphere, clouds, and winds respond to these long seasons, although the exact mechanisms are still being studied. Uranus offers a rare example of how axial tilt can dominate planetary climate.
