Summary and Conclusions
•6 storm sample for 2000 West Pacific season
–Overall, good
comparison between JTWC and SAB ODT estimates
–JTWC and SAB ODT Final
T# estimates were typically within 0.5 T# of
JTWC Best Track estimates
–Very cold cloud temperatures led to high bias in Final T# relative to JTWC Best Track estimates (cloud temperatures < upper -70°C)
–Rapid intensification
flag correctly identified events but led to large Final T# high bias when coupled with very cold cloud top
temperatures (tuning
to West Pacific needed)
•Slight differences between JTWC and SAB ODT estimates
–Possible errors with
ocean basin identification (basin flag is manually adjusted; could be automated)
–Implementation of 48 Hour Rule is slightly different between JTWC and SAB due to different ODT versions (fixed vs. time-weighted value)
•Overall, CI#s provided better fit to JTWC Best Track
estimate than Final
T#s during weakening
