The North Atlantic tropical cyclone track data for 2020 (hurdat2) has finally been released by the NHC. It was such a busy year that it must have taken till now to ratify or whatever it is they’ve been doing to the data for the last six months. For the more eagle eyed amongst you, you may notice that my app doesn’t list the entry for Ten as a tropical cyclone because maximum winds reached only 30 knots and it was only classified as a tropical depression. I wonder if 2021 will surpass last year? I’ve been closely monitoring tropical cyclones in the Atlantic for ten years or more now and it seemed that last year the NHC were on an even a higher state of heightened alert than normal, naming anything that remotely could develop a vortex. Six of the named storms never made it beyond 40 knots and two survived for no more than 36 hours.
The 30 tropical cyclones in the 2020 season may have have just pipped 2005 into second place with 29, but the total ACE of the cyclones in 2020 was only 72% of the total ACE of the cyclones in 2005. I wonder just how many extra tropical cyclones they would have found in the 1933 season if they had had the sophisticated surveillance techniques we have today?
