Seasons occur because Earth is tilted on its axis relative to the orbital plane, the invisible, flat disc where most objects in the solar system orbit the sun. This draws in more humid air from surrounding areas, and as the air rushes in, the Coriolis effect, created by the Earth’s spin, causes it to follow a curved path, leading the developing storm to spin anticlockwise in the northern hemisphere. A season with many strong, long-lasting storms will have a higher ACE than a season with shorter-lived, weaker storms.
