2024 Is Likely To Be Another Year With A High Level Of Hurricane Intensity

According to https://tropical.atmos.colostate.edu/Realtime/index.php?arch&loc=northatlantic, the accumulated cyclone energy of North Atlantic cyclones has been above 95 for each of the past 8 years (2016 thru 2023) and above 100 for 7 of the last 8 (2022 was the outlier with 95). Comparing this result to the previous 30 years, 14 out of the previous 30 years had accumulated energy below 95 (47%). I doubt many readers of this blog will be surprised by the fact that years with accumulated cyclone energy of North Atlantic hurricanes with high intensities are becoming more frequent.

I conducted this review because I speculated it highly likely that given the warmer ocean temperatures, that the Carribean Islands, Atlantic and Gulf of Mexco coastal communities are likely to be devastated by the next round of hurricanes following the flip of ENSO to La Nina.

However, when comparing accumulated energy years to El Nino and La Nina years, I found that while there is definitely a correlation, it is not as strong as I had expected to find https://ggweather.com/enso/oni.htm. While El Niño generally tends to suppress Atlantic hurricane activity, and La Niña tends to enhance it, an eyeball review of the results suggests that it does not appear to be highly predictive of whether there will be destructive hurricane activity in 2024. Thus, if there is a flip of the ENSO cycle from El Niño to La Niña, as some forecasters are predicting, it makes a devastating hurricane season more likely but not a certainty.

While coastal communities may not be as vulnerable to hurricanes in 2024 as I had supposed before starting this review, I fear that the warmer ocean temperatures will lead to more devastating Atlantic hurricanes in the not too distant future during both El Niño and La Niña years.
