Information icon Hello! I'm Jasper Deng. Your recent edit(s) to the page Typhoon Yagi (2024) appear to have added incorrect information, so they have been reverted for now.

If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Nowhere in the following prognostic reasoning message does it say 155 kt:

WDPN31 PGTW 060900 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/PROGNOSTIC REASONING FOR TYPHOON 12W (YAGI) WARNING NR 020// RMKS/ 1. FOR METEOROLOGISTS. 2. 6 HOUR SUMMARY AND ANALYSIS.

SUMMARY: 

  INITIAL POSITION: 19.7N 111.3E
  INITIAL INTENSITY: 125 KTS
  GEOGRAPHIC REFERENCE: 314 NM EAST-SOUTHEAST OF HANOI, VIETNAM
  MOVEMENT PAST 6 HOURS: WEST-NORTHWESTWARD AT 10 KTS
  SIGNIFICANT WAVE HEIGHT: 51 FEET

SATELLITE ANALYSIS, INITIAL POSITION AND INTENSITY DISCUSSION: AS INDICATED IN ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY, TYPHOON (TY) 12W IS BEGINNING TO WEAKEN AS IT MAKES LANDFALL OVER NORTHERN HAINAN ISLAND. HOWEVER, EIR IMAGERY AND RADAR IMAGERY CONTINUE TO SHOW A ROUND 21NM EYE WITH A NEAR COMPLETE EYEWALL AND SPIRAL BANDING OVER THE SOUTHERN SEMICIRCLE. ALTHOUGH THE EYEWALL IS BEGINNING TO ERODE OVER THE WESTERN QUADRANT, THE OVERALL STRUCTURE REMAINS WELL-ORGANIZED WITH EXTENSIVE SPIRAL BANDING OVER ALL QUADRANTS. SURFACE OBSERVATIONS AT HAIKOU (ZJHK), OVER NORTHERN HAINAN ISLAND, HAVE INCREASED QUICKLY TO 52 KNOTS SUSTAINED (10-MINUTE AVERAGE) GUSTING TO 8O KNOTS, WITH SLP NEAR 970MB. OVERALL, THERE IS HIGH CONFIDENCE IN THE INITIAL POSITION BASED ON THE EIR IMAGERY. THE INITIAL INTENSITY IS ASSESSED AT 125 KNOTS BASED ON THE LOWER END OF THE AGENCY DVORAK CURRENT INTENSITY ESTIMATES AND OBJECTIVE INTENSITY ESTIMATES RANGING FROM 116 TO 132 KNOTS.

INITIAL WIND RADII BASIS: SAR DATA

CURRENT STEERING MECHANISM: DEEP-LAYERED SUBTROPICAL RIDGE (STR) ENTRENCHED OVER CENTRAL AND EASTERN CHINA.

AGENCY DVORAK AND AUTOMATED FIXES: 

  PGTW: T7.0 - 140 KTS 
  RJTD: T6.5 - 127 KTS
  KNES: T6.5 - 127 KTS
  DEMS: T7.0 - 140 KTS 
  CIMSS ADT: 132 KTS AT 060600Z
  CIMSS AIDT: 123 KTS AT 060600Z
  CIMSS DPRINT: 116 KTS AT 060600Z
  CIMSS DMINT: 127 KTS AT 060551Z

FORECASTER ASSESSMENT OF CURRENT ENVIRONMENT: MARGINALLY FAVORABLE 

  VWS: 0-5 KTS
  SST: 30-31 CELSIUS
  OUTFLOW: MODERATE RADIAL
  OTHER FACTORS: LAND INTERACTION

ANALYSIS CONFIDENCE: 

  INITIAL POSITION: HIGH
  INITIAL INTENSITY: MEDIUM
  INITIAL WIND RADII: MEDIUM

3. FORECAST REASONING.

SIGNIFICANT FORECAST CHANGES: THERE ARE NO SIGNIFICANT CHANGES TO THE FORECAST FROM THE PREVIOUS WARNING.

FORECAST DISCUSSION: TY 12W IS FORECAST TO TRACK WESTWARD TO WEST- NORTHWESTWARD THROUGH THE FORECAST PERIOD. AS THE SYSTEM TRACKS OVER HAINAN ISLAND, RAPID WEAKENING WILL COMMENCE DUE TO INTERACTION WITH THE RUGGED TERRAIN. AFTER TAU 12, TY 12W WILL WEAKEN FURTHER AS IT TRACKS ACROSS THE GULF OF TONKIN, WITH LANDFALL OVER NORTHERN VIETNAM EXPECTED NEAR TAU 24. AS THE SYSTEM TRACKS INTO NORTHERN VIETNAM, IT WILL WEAKEN RAPIDLY AND DISSIPATE BY TAU 72.

MODEL DISCUSSION: DETERMINISTIC MODEL GUIDANCE USED IN THE JTWC CONSENSUS (CONW) REMAINS IN TIGHT AGREEMENT WITH A 40NM CROSS-TRACK SPREAD AT TAU 24. PROBABILISTIC GUIDANCE FROM THE ECMWF (EPS) AND GFS (GEFS) ENSEMBLES ALSO REMAINS IN TIGHT AGREEMENT SUPPORTING THE JTWC TRACK FORECAST WITH HIGH CONFIDENCE. RELIABLE INTENSITY GUIDANCE IS ALSO IN VERY GOOD AGREEMENT SUPPORTING THE RAPID WEAKENING PHASE EXPECTED AFTER TAU 12.

FORECAST CONFIDENCE: 

  TRACK 0 - 72 HR: HIGH
  INTENSITY 0 - 72 HR: MEDIUM//

I see the previous reasoning mentioned RCTP giving a T7.5 = 155 kt fix, but that was not JTWC's final intensity determination by any means.--Jasper Deng (talk) 08:49, 6 September 2024 (UTC)[reply]
The prognostic reasoning message issued by JTWC at 6 Sep 0300Z had one measurement of 155 kts:

AGENCY DVORAK AND AUTOMATED FIXES:
PGTW: T7.0 - 140 KTS
RJTD: T7.0 - 140 KTS
RCTP: T7.5 - 155 KTS
KNES: T6.0 - 115 KTS
CIMSS SATCON: 145 KTS AT 052130Z
CIMSS ADT: 132 KTS AT 060000Z

Those are not measurements. Those are Dvorak technique estimates, and even if they were measurements, the "MAX SUSTAINED WINDS" at the top is JTWC's official conclusion from that data and is what is used in the article.--Jasper Deng (talk) 09:04, 6 September 2024 (UTC)[reply]
