  1. ConcerningThunderstorm(Potential) prediction Jan PARFINIEWICZ , Inst. of Meteorology and Water Management,MOLC 01-673 Warszawa, ul. Podleśna 61, Poland

  2. Essential:Self-learning EngineThunderstorms QuantificationEnd-User oriented Warning System

  3. Self-learning Engines:1) Kalman Filter (KF)2) Artificial Neural Network some generalisation to KF:after each signal an automatic renewal of the multi-regression set ofparametersKF++’s: basic statistics allows on dispersion control (clasical physics)

  7. End-User oriented Warning System End-User = Casualties Essential: EMPATHY to CASUALTIES categories: 1) Presentation system (W. Łazarewicz) 2) Precise Warning Message System 3) End-User Entity including Verification

  8. Presentation: http://awiacja.imgw.pl1)Observed storms: all moderate severe … time scale time scale Severe Tornado

  9. Presentation: http://awiacja.imgw.plcategories: 1) Observed storms 2) Possible danger zone Pb+ = 1 3) Storm Potential 4) Strength of convection model option COSMO: 07km/14km Observed storms 2) Possible danger zone Pb+ = 1

  10. CONCLUSIONS Include Tornado’s scaling into prediction Continue search for potential predictors Dewelop 3-step Warnig System :12h, 3h, 1/2h
