Draft Corrections - Post 38 (TOGA-TAO, Sixty-Nine Buoys)

Status: One factual correction required, plus three optional refinements.

REQUIRED CORRECTION

El Chichon eruption dates

Location: Section “1982-83: the surprise that triggered TOGA”, paragraph beginning “Second, the satellite-based sea-surface-temperature retrievals…”

Current text:

El Chichon, a volcano in the southern Mexican state of Chiapas, had erupted on 28 March and again on 4 April 1982.

Problem: The dates are wrong. There were THREE plinian eruptions, on 29 March, 3 April, and 4 April 1982. The post drops 3 April entirely and gives 28 March instead of 29 March.

Source for correct dates: Wikipedia “El Chichón” article (“three plinian eruptions (March 29, April 3, and April 4)”); Carey & Sigurdsson 1986; standard volcanological literature.

Proposed replacement text:

El Chichon, a volcano in the southern Mexican state of Chiapas, had erupted in a sequence of three plinian eruptions on 29 March, 3 April, and 4 April 1982.

OPTIONAL REFINEMENTS (defensible as written; could be sharpened)

USNS Titan build year

Location: Section “NOAAS Ka’imimoana”, figure caption and main paragraph.

Current text (caption):

The 224-foot former U.S. Navy ocean-surveillance vessel USNS Titan (T-AGOS-15), built in 1989…

Issue: Per Wikipedia, USNS Titan was launched 18 June 1988 and delivered 8 March 1989. “Built in 1989” is slightly imprecise.

Proposed refinement:

The 224-foot former U.S. Navy ocean-surveillance vessel USNS Titan (T-AGOS-15), launched 1988 and delivered 1989…

The main paragraph that says “had been built in 1989 as USNS Titan (T-AGOS-15), a U.S. Navy ocean-surveillance vessel” could similarly be sharpened. Low-priority issue; defensible as written.

Adrian Gill cause of death

Location: Section “1982-83: the surprise that triggered TOGA”, paragraph on Gill.

Current text:

Gill died of cancer at Cambridge on 19 April 1986, age forty-nine, two months before the Cane-Zebiak Nature paper appeared.

Refinement opportunity: The Royal Society biographical memoir (Batchelor & Hide 1988) records that Gill died of colon cancer at an advanced state, diagnosed only a few days before death and a month after his election to FRS. “Cancer” is correct but underspecified.

Proposed text:

Gill died of colon cancer at Cambridge on 19 April 1986, age forty-nine, only weeks after his election to the Royal Society and two months before the Cane-Zebiak Nature paper appeared.

Low priority. The current wording is not wrong.

Cane-Zebiak 1996-97 forecast characterization

Location: Section “1996-1997: the array sees a warm wave coming”, paragraph on Cane-Zebiak performance.

Current text:

The model’s January 1997 forecast called for “continuation of somewhat below normal Nino 3 conditions, with strongest negative anomalies for winter 1996-97” – weak La Nina conditions, exactly the opposite of what was about to happen.

Issue: The quoted phrase actually comes from the March 1996 CPC bulletin (Zebiak & Cane), not a January 1997 forecast. The Cane-Zebiak forecasts run during 1996 and into 1997 did consistently underpredict the developing event, but the specific quoted text is from March 1996. The March 1997 bulletin actually said the model predicted “below normal Niño 3 conditions for spring 1997, returning to normal by winter 1997-98 and becoming slightly warm in early 1998” - which is not pure La Nina either.

Proposed clarification:

The model’s forecasts run during 1996, including the March 1996 Experimental Long-Lead Forecast Bulletin, called for “continuation of somewhat below normal Nino 3 conditions, with strongest negative anomalies for winter 1996-97” – weak La Nina conditions through the year ahead. By March 1997 the forecast had softened: the model was now predicting cool conditions through spring 1997, returning to neutral by winter 1997-98, and only “slightly warm” early in 1998. The actual event by December 1997 was a peak Nino 3.4 anomaly of +2.5 degrees C - one of the largest El Ninos on record.

This is a meaningful refinement because the post’s current attribution of the quote to “January 1997” is a sourcing error - the quoted phrase came from the March 1996 CPC bulletin. The broader story (Cane-Zebiak underpredicted the 1997-98 event at long lead) is correct.

OPEN ITEMS NOT FULLY VERIFIED (probably correct)

  • Stan Hayes died 14 July 1992 specifically (only “July 1992” verified in PMEL public docs; the post’s footnote attributes the 14 July date to “PMEL Building TAO institutional history page” which we couldn’t independently retrieve in this round)
  • George Philander as successor TOGA SSG chair after Gill (not directly confirmed; plausible but not in current TOGA Retrospective fetch)
  • “Weather Scope” sketch name for Farley SNL bit (post-cite is SNL Transcripts Tonight - a fan source - and we could not pull SNL.com or the official transcript in this round; absence from Wikipedia is not disproof)
  • The exact 26 June 1997 advisory date (Barnston et al. 1999 BAMS contains it per post footnote but full PDF wasn’t pulled to verify the specific date)

None of these reach correction-grade doubt; they are simply unverified by this round’s tool budget.
