Annual cycle of sea level height

The annual cycle of sea level height refers to the seasonal fluctuations in sea level that occur due to a variety of factors, including temperature, precipitation, and wind patterns. Here are some key components that contribute to this cycle: 1. **Thermal Expansion**: Sea water expands as it warms. During warmer months, typically around summer in each hemisphere, sea surface temperatures rise, leading to thermal expansion and a slight increase in sea level.
