Atlantic hurricane reanalysis results
It looks like it has been a while since this forum was utilized. However, seeing that there has not been any recent discussion about the ongoing Atlantic hurricane reanalysis, I think it is a good idea to talk about the latest changes. Last November (2019), the Atlantic Oceanographic and Meteorological Laboratory (AOML) finalized their reanalysis for the 1961 to 1965 Atlantic hurricane seasons. Here were the major revisions I observed:
- Hurricanes Anna and Debbie from 1961 were downgraded to Category 2 and 1 intensity, respectively. This means 1961 only had five major hurricanes and 2005 (after 14 years) now singlehandedly holds the record for most major hurricanes in an Atlantic season. That being said, 1961 also ties with 1933, 1999, and 2005 for having the most Category 4 hurricanes (5) in a single year.
- Also, it turns out Hurricane Debbie was extratropical after all when it made landfall in Ireland. Hurricane Vince is now the only tropical cyclone that made landfall in Europe as such.
- Hurricane Carla was downgraded to a Category 4 hurricane, but Hurricane Esther was upgraded to a Category 5. Moreover, an unnamed tropical storm was discovered in November and Hurricane Hattie remains a Category 5. 1961 is now tied with 2001 and 2005 for having the most November storm formations (3).
- It appears that Hattie and Inga are still separate systems. I remember some weather enthusiasts claiming that Hattie, Tropical Storm Simone in the EPAC, and Inga were just one tropical cyclone, but the official reanalysis says otherwise. Also, Tropical Storm Simone was never actually a tropical system (only a cyclonic gyre).
- An unnamed tropical storm and hurricane were discovered at the beginning and at the end of the 1962 season, respectively.
- Hurricane Ella was downgraded to a Category 2 hurricane. There are now six seasons since 1950 that have not had major hurricanes: 1962, 1968, 1972, 1986, 1994, and 2013.
- An unnamed tropical storm in June 1963 was added to the database, and Hurricane Arlene from that same year is now a Category 3 major hurricane.
- The original Tropical Storm Three (now Four) and Hurricane Cindy from 1963 "swapped intensities". In other words, the former was upgraded to a Category 1 hurricane, and the latter was downgraded to a tropical storm.
- An unnamed tropical storm was discovered at the end of July 1964.
- The original Tropical Storm Two (now Three) from 1964 was upgraded to a Category 1 hurricane, and Hurricane Ethel was downgraded to a Category 2. Unfortunately, this means the 1964 season has lost its defining characteristic for me, as not every hurricane became a major after all.
- Hurricane Hilda's Louisiana landfall intensity was downgraded to a Category 2 hurricane (and only Dora and Isbell were landfalling U.S. major hurricanes in 1964). On the contrary, Billion-Dollar Hurricane Betsy from 1965 was actually a Category 4 hurricane when it struck Louisiana.
- Four new tropical storms in 1965 were added to the Atlantic hurricane database.
- I knew a little about this reanalysis when Dylan linked a video talking about this in Beryl's archive in the Atlantic two years ago in July 2018, but apparently they only went up to 1965 in their recent update. I heard the following changes might also happen in that video, for the 1966-1970 Atlantic seasons:
- Inez might be upgraded to a category 5 in reanalysis around when it struck Haiti, and Faith's track as a tropical cyclone will be significantly cut short; it actually turned extratropical long before reaching Europe.
- Beula of 1967 will probably be downgraded to a category 4 storm in reanalysis, like Carla '61 was.
- A post-season hurricane might be added to one of those years.
- And Celia of 1970 was actually a 130 mph cat 4 when she struck Corpus Christi, Texas.
