Services & Products of Tokyo VAAC Jun Ryuzaki 30 October, 2012 FPAW in Orlando Tokyo Volcanic Ash Advisory Center Japan Meteorological Agency Area of Responsibility Tokyo VAAC • Tokyo VAAC started its operation in 1997 • Close coordination with Anchorage & Washington VAAC. “Busiest” VAAC in the World? Bezymianny ( 2 ) Kliuchevskoi ( 11 ) 60N ▲ ▲ ▲ ▲ 50N Sheveluch ( 179 ) Kizimen ( 223 ) Karymsky ( 52 ) 40N Asosan( 56 ) Kirishimayama( 184 ) Sakurajima ( 1000 ) 30N ▲ ▲ ▲ ▲ Suwanosejima ( 37 ) ▲ ： Volcanoes location Black letters : Volcano Name Blue Number : Number of Issued VAAs 20N ▲ Bulusan( 30 ) + Other transfer VAAs ▲ Grimsvotn( 5 ) ▲ Pagan ( 6 ) 10N 100E 110E 120E 130E 140E 150E 160E 170E • 1785 VAAs were issued for 12 volcanoes only in 2011. 3 Operational Efforts of JMA • Dedicated VA forecaster (since 2011) • Close collaboration with JMA volcanologists • Semi-Automated operating system with GUI Tokyo VAAC operations room in Tokyo, JMA HQs Information Flow of VAA Volcano Information Pilot Reports Satellite Observations Tokyo VAAC/JMA Volcanic Activity Reports • • • NWP GPV Monitoring & Analysis of VA Cloud Forecasting of Volcanic Ash Issue of Volcanic Ash Advisory (VAA) • ICAO ANNEX3 VA products Text VAA (FVFE01) / Graphical VAA (VAG) • Additional VA products (Domestic) Graphical products (VAGI, VAGFN, VAGFNR) Foreign VAACs Meteorological Watch Offices in area of responsibility Aviation Weather Service Centers in Japan Civil Aviation Authorities and Other Related Organizations Additional VA Products (Example) • Volcanic Ash Graphic Information (VAGI) VA area identified with Satellite imagery Major Air-Route Top Height (FL) Movement/Speed 6 Experimental VA Product • “Volcanic Ash Dispersion Chart for Mt. Sakurasima & Mr. Kirishimayama” – Assuming Eruption of 2 very active Volcanoes – Forecast up to 3 hours later,3 hourly updated – Ash Dispersion and Deposition from the two volcanoes • Help Air Traffic Controllers, Airline Dispatchers, and Aircraft pilots; – Immediate response to mitigate risk of VA encounter – Consider possibility of VA fall over airports nearby • Now under Evaluation by Users – Started since 29 July,2010 7 Experimental VA Product Miyazaki Airport Kagoshima Airport FL100 to FL200 Surface to FL200 FT=1 FT=2 FT=3 8 Further Development • Deposition Area will be directly forecasted – by JMA’s future VA deposition prediction model Estimation of ash dispersion/deposition for assumed eruption of Mt. Sakurasima & Mt. Kirishimayama Deposition Area (Hatced) 9 Future Improvement in Observation Field • New MET Satellite will be launched in 2015 – Multi-Channel Sensors equipped – Rapid Scan (every 10 minutes) – High Resolution (1km) • Ground Radar Observation for VA – VA Height and Vertical Profile can be obtained 10 Further Efforts… • Enhance collaboration with Anchorage VAAC – Use of collaboration tool (being discussed) • Establish ment of back-up procedure – With Darwin VAAC (Australia) – Routine exercise also will start soon • Improve harmonization between VAACs – VAAC Best Practice Seminar • Enhance contribution to scientific groups – WMO VA Scientific Advisory Group (VASAG), the other related seminar/workshops 11 Thank you! 12
