If there was any company that I would trust less with a web browser (and related user data) than an ad-tech company, it would be an AI company.

Accumulated Cyclone Energy (ACE) https://tropical.atmos.colostate.edu/Realtime/

The figure in parentheses is ACE, averaged over 30 years up to and including September 30th: 77.8 (94.1)

There's more detail here, including a helpful chart: https://tropical.atmos.colostate.edu/Realtime/index.php?loc=...

EDIT: Interesting that Beryl had more ACE than Helene. I wonder if that figure will change as the effects from Helene are investigated further?

sudenmorsian · a year ago
No, Helene's ACE will remain unchanged until the post-season analysis of both storms. It's a measure of the storm's duration and intensity; Helene was a rather short-lived storm with the intense period only occuring for a short time compared to Beryl which is why it has such a lower value than Beryl.

While I like a good conspiracy, it seems to me as though this was a perfectly appropriate outcome of technological advancement. Surely old storms would be biased high given a variety of reasons.
sudenmorsian · 2 years ago
It's been acknowledged in the meteorological community that reconnaissance wind speed estimates for storms in the 1950s and 1960s have a high bias in the most intense storms, as the field was still in its infancy during that time period. Further advancement in later decades has improved the confidence in the estimates.

No conspiracy needed. After all, the first time a hurricane was intentionally flown into by a storm was only in 1943: https://en.wikipedia.org/wiki/1943_Surprise_Hurricane. The 1950s and 1960s are not that far removed from that initial attempt.

Confusingly, that wikipedia page cites the same IBTrACS system that I referred to, and in that page[0] the max intensity is listed at 213 knots. The data shows that the 213 knot speed was seen for measurements across twelve hours on 1958-09-24.

You are looking at the data for the CMA (China Meteorological Agency). The official data center for the Western Pacific according to the World Meteorological Agency is the Japan Meteorological Agency (JMA/Tokyo), but the IBTrACS dataset does not have wind speeds from them for 1958.

The Wikipedia article is sourcing data from the JTWC (Joint Typhoon Warning Center), the US wind column for 1-minute sustained wind speeds. In general, the Wikipedia convention is to include wind speed data from the JMA and JTWC when available.

I've read that 'tl' was similar to the welsh 'll' sound (a kind of hissy L sound, though not really, youtube will have some spoken examples) but when I've heard 'tl' spoken it usually sounds like a 'tl', as in 'little'.
sudenmorsian · 3 years ago
Yes, it’s a very similar sound. The Welsh <ll> is the voiceless lateral fricative /ɬ/, which is effectively <tl> without the initial ‘t’ at the start of the phoneme.

See: https://en.wikipedia.org/wiki/Voiceless_dental_and_alveolar_...
