It hit the central Philippines on Saturday, killing at least 32 people and leaving more than 1,000 others homeless. Typhoons happen. Is there a point to all of this? Bob Kolker News Group. This is news. STRONGEST EVER IN HISTORY South China Sea Typhoon in month of May. 2nd busiest sea lanes in the world, 67,000 ships recalled to port or diverted, increase fuel costs, slipped schedules, economic impacts. More significant than if Barry Bonds hits a home run or not. Over 10,000,000 people were in the projected impact path when the storm was cat-5. Physics, Econ, Environment, Global Warming, Meteorology issues. If you are not interested, unsubscribe and not receive postings on subjects outside your limited interest range. QUESTIONS: What "invisible wall" did typhoon Chanchu hit? It was moving due west -- halted abruptly, made sharp right turn due north. Went from Category 1 to category 5 strength in 24 hours. Mystery -- What physics forces can make this happen? Nothing on the satellite screens can account for this behavior, was spinning off rainbands due west for many hours -- no "invisible wall" there then. Even after course change continued spinning off rainbands by centrifugal force to the west without visible wind shear impacting the thrust of these rainbands. What force known to science can change a cat-5 hurricane path 90 degrees without it affecting the rainbands? Mystery? This is news. This is newsgroups. Get with it or get out. BJ/PROGNOSTIC REASONING FOR TYPHOON 02W WARNING NR 36// RMKS/ 1. FOR METEOROLOGISTS. 2. PROGNOSTIC REASONING FOR 171200Z TO 190000Z MAY 2006. A. TYPHOON (TY) 02W (CHANCHU), LOCATED APPROXIMATELY 130 NM EAST OF HONG KONG, HAS TRACKED NORTH-NORTHEASTWARD AT 13 KNOTS OVER THE PAST 06 HOURS. ANIMATED SATELLITE IMAGERY AND A 171032Z SSM/I PASS INDICATE THAT TY 02W HAS BEGUN TRANSITIONING TO AN EXTRATROPICAL CYCLONE. B. TY 02W CONTINUES TO TRACK POLEWARD ALONG THE WESTERN PERI- PHERY OF A MID-LEVEL STEERING RIDGE CENTERED EAST OF TAIWAN. TY 02W IS FORECAST TO TURN NORTHEASTWARD IN RESPONSE TO A WEAKENESS DEVELOPING IN THE STEERING RIDGE CAUSED BY AN APPROACHING MID- LATITUDE TROUGH. TY 02W IS FORECAST TO MAKE LANDFALL EAST OF HONG KONG BY TAU 12. SATELITE IMAGERY INDICATES THAT TY 02W IS IN THE INITIAL STAGES OF EXTRATROPICAL TRANSITION; THIS TRANSITION IS FORECAST TO BE COMPLETE BY TAU 24. THE EXTRATROPICAL CIRCULATION WILL EXIT CHINA SOUTH OF SHANGHAI BY TAU 36. THE AVAILABLE DYNAMIC AIDS CONSISTING OF NOGAPS, GFDN, COAMPS, AFWA MM5, NCEP GFS, JGSM, JTYM, UKMET EGRR, TCLAPS, AND WBAR ARE IN FAIR AGREEMENT WITH THIS SCENARIO THROUGH TAU 36. VARIATION IN THE WESTWARD EXTENSION OF THE STEERING RIDGE CAUSE DIFFERENCES IN THE MODEL FORECAST TRACKS. THIS FORECAST IS BASED ON A CONSENSUS OF ALL AVAILABLE DYNAMIC AIDS. C. TY 02W HAS WEAKENED SLOWLY OVER THE PAST 24 HOURS AS IT APPROACHES SOUTHERN CHINA. RECENT MICROWAVE IMAGERY REVEALS ERO- SION OF THE CONVECTION IN THE WESTERN QUADRANTS, AND A BREAKDOWN OF THE DEEP CONVECTION IN THE EYEWALL. RAPID WEAKENING WILL OCCUR BY TAU 12 AS THE STORM TRACKS OVER LAND AND COMPLETES EXTRATROPICAL TRANSITION. D. CURRENT WIND RADII ARE BASED ON A 171032Z SSM/I PASS. FORE- CAST WIND RADII ARE BASED ON CLIMATOLOGY FOR AN AVERAGE- TO LARGE- SIZED SYSTEM. 3. FORECAST TEAM: ALPHA// NNNN |
