  1. IMPACTS: TROPICAL CYCLONES and their effects on the Department of Defense and others Typhoon Omar (15W) , Guam, August 1992 HQ AFWA/XOGM

  2. TROPICAL CYCLONES • DoD • Resource Protection • Mission • Aviation • Low Level Wind Shear • Naval Shipping • Costs • Position/Forecast • General • Winds • Sea State / Surf • Storm surge • Precipitation • Destructive potential • Loss of Life

  3. WINDS • Wind Damage: • Small Objects become missiles. • Great threat to personnel safety • Damage to living quarters, military and civilian infrastructure Courtesy: Dr. Steve Businger Univ. Hawaii/Manoa Hurricane Iniki, Hawaii, 1992

  4. Hurricane Floyd (15W), US Eastern Seaboard, September 1999

  5. SEA STATE/SURF • Difficult conditions for vessels at sea. • Beach Erosion, and difficulty in rescue operations Courtesy: Dr. Steve Businger Univ. Hawaii/Manoa

  6. STORM SURGE • Large “mound of water”. • Most Deaths occur in Storm surge • Damage to Low lying areas near coast • Extensive flooding

  7. Hurricane Floyd (15W), US Eastern Seaboard, September 1999

  8. STORM SURGE • Large “mound of water”. • Most Deaths occur in Storm surge • Damage to Low lying areas near coast • Extensive flooding

  9. STORM SURGE • Large “mound of water”. • Most Deaths occur in Storm surge • Damage to Low lying areas near coast • Extensive flooding

  10. STORM SURGE • Large “mound of water”. • Most Deaths occur in Storm surge • Damage to Low lying areas near coast • Extensive flooding

  11. PRECIPITATION • Extensive flooding over inland areas • Large Loss of life ; no protection • Dramatic Economic impact; Humanitarian relief needed

  36. Resource Protection The eye passage of Typhoon Omar (15W) from August 1992 This storm impacted Five major military installations on Guam, shutting down all normal operations Thus the DoD mission is impeded….. . NCTAMS

  38. Aviation Hazards Aircraft operating near a tropical cyclone will be subjected to significant Low Level Wind Shear. Also, some aircraft cannot take off if the crosswinds over an airstrip exceed a certain value. In the overwhelming majority of cases, 35 knot winds (tropical gale wind envelope) exceeds this threshhold for military aircraft (Can’t take off, can’t launch helicopter for rescue operations). These turbulent conditions can become a very dangerous hazard to equipment and personnel safety.

  43. DATELINE: October 31, 2000 -- Updated 06:14 p.m. EST, 2314 GMT (From CNN.com) Taiwan says 65 dead in Singapore Airlines crash Taiwanese officials say that at least 65 people died when Los Angles-bound Singapore Airlines Flight 006 crashed during takeoff in stormy weather in Taipei late Tuesday. James Boyd, an airline spokesman in Los Angeles, said that according to the latest information available from the crash site, 75 people on board the Boeing 747-400 were unaccounted for.

  44. DATELINE: October 31, 2000 -- Updated 06:14 p.m. EST, 2314 GMT (From CNN.com) Taiwan says 65 dead in Singapore Airlines crash CNN Meteorologist Orelon Sydney reports the weather at the time of takeoff "was the equivalent of a Category 2 hurricane making landfall on the island. Shortly after the crash, bands of bad weather extending outward from Typhoon Xangsane were creating winds measured from 40 to 73 mph, Sydney said.
