Slightly off-topic, but I will forever be fascinated and mystified by the 1933 Atlantic Season, which actually surpassed 2005 in terms of ACE and in my opinion almost certainly had far more name-worthy storms than its official tally, given that it occurred before satellites and therefore would have missed a huge number of recurving fish storms.
I would love
to get my hands on the kind of teleconnection data we have access to now (global SST anomalies, SAL analyses, wind shear etc) to compare the 1933 season with 2005, 2017 and 2020, as I'm very much convinced that there are as-yet undiscovered teleconnections which make hurricane seasons more or less active, beyond the well known markers such as ENSO, PDO, AMO, IOD etc.
2005, for example, did not feature a La Nina event but featured a prolonged period of severely curtailed convection in the Central Pacific, almost like a season-long standing wave of subsidence and an equivalent standing wave of enhancement over the Atlantic. None of the obvious teleconnections account for what might cause these conditions and obviously for 1933 there just isn't enough data, but it raises the possibility that there are other processes involved which we don't understand yet, and I for one can't get enough of that kind of thing
EDIT: To give one simple example: Do we know what caused the African Easterly Jet to slow to a crawl during peak season, such that tropical waves got stuck in the East Atlantic and moved far too slowly to develop? And could this have been predicted ahead of time? It seems to have caught every forecasting agency and meteorologist off guard. The wave which became Paulette, for instance, seemed to take forever to actually make it into the Atlantic after the NHC tagged it as an invest inland over Africa and even then it crawled
along for the first few days.
