Presentation Transcript

  1. AdcircLite-NC Project Updates Jesse Bikman Brian Blanton

  2. Progress since last meeting • Ran cross validation with different parameters included/excluded (perturbation scenarios) • Augmented parameter set with DB_latP1/DB_latP2 describing distance along intersection with given latitude parallels • DB_latP1/DB_latP2 better characterizes the storm population than TH/DB • Defined some new error metrics to supplement evaluation of cross validation runs

  3. New Distance Parameters Longitude separation between track line intersection point and reference longitudes on latitudes 34.5 and 36.0 N DB_latP2 DB_latP1

  4. Parameter perturbation scenarios We have adopted the 2 latitude distances in lieu of the distance/angle parameters.

  5. Error metrics Si = original model value at response point i S*i = surrogate model value at response point i Ei = error at response point i = S*i – Si N = total # response points M = # response points where 0.5(Si + S*i) > threshold value

  6. Scenario Statistics
