Question: Why exactly were Greek letters used as names for Hurricanes in the first place, despite the fairly obvious and predictable impracticalities? Certainly this exact problem was brought up, how was it dismissed?
Related but different (because the current question is backward-looking), and also in need of answers:
But if you say, "aren't the number of tropical cyclones supposed to increase under climate change?" to challenge my assumption of constant tropical cyclones per decade, I will argue that canonically, the frequency that tropical cyclones form should decrease, but the intensity should increase. So the assumption doesn't actually hold, but should actually overestimate the probability of more hurricanes in the long term.
So why use Greek letters? Well, to be consistent, something has to be used to draw attention to the storm. Cycling back to the A's sends the wrong message. And the Greek alphabet was used previously, without major consequence.
Arguably, it may be easier to only name storms that make hurricane strength. However, that would be inconsistent, and may miss strong, rain-heavy storms. For example, Tropical Storm Allison was retired without making the hurricane wind requirement.
