Facts of Life • NOAC has a small staff with many deployed • C 7 F sets sortie conditions • NOAC main focus is ASW – Resource protection is NOAC’s “side job” • Timing is very important for morning Typhoon Battle Rhythm in order to support CNFJ morning brief. – NOAC needs to assess – Conference call – Prep brief • People in Japan get very concerned when JTWC says one thing but when they go to JMA’s webpage, they get confused/tense when there is a difference and it leaves NOAC in the uncomfortable position of trying to explain the delta.

Final Thoughts • C 7 F and CNFJ are generally “Happy” • We appreciate: – Early communications when major changes are expected. – Early Warnings- warn on priority systems first (ie. Storm tracking to make land fall on Japan before one that will make land fall on China) – Not dropping warnings when storm goes extratropical until after passes naval facilities • We need better understanding: – Wind Probabilities products, How to apply to TCCOR Recommendations – Wind Radii Depictions for systems undergoing extra tropical transition – Anticipated rain amounts (minor flooding in housing) – Potential for significant storm surge Naval Oceanography 14
