From this tweet. Additional, how would we know, and how would this be a stationary target given global warming or general changes?

Air has friction. As hurricane winds get faster, there is more friction resisting them.

Hurricanes get power from warm ocean water. Depending on the ocean temperature, there is only so much power available to overcome friction and make stronger winds. This is why big hurricanes usually happen in the late summer and early fall, when the ocean is warmest.

Physicists can calculate the maximum wind speed that a hurricane can achieve for a given ocean temperature. *This is not stationary.* As the ocean warms due to climate change, this maximum wind speed increases.
