Impacts of Oceanic Preexisting Conditions on Predictions of Typhoon Hai-Tang in 2005
Figure 1
(a) Time series of best-track central pressure, tropical-cyclone heat potential (TCHP), isotherm depth (Z26), and sea surface height (SSH) from 1200 UTC 12 July to 1200 UTC 15 July 2005. (b) Horizontal distribution of the 7-day mean SSH (cm) obtained from the Archiving and Validating Interpretation of Satellite Oceanographic (AVISO) data product (ftp://ftp.aviso.oceanobs.com/pub/oceano/AVISO/SSH/duacs/global/dt/ref/madt/merged/h/) for 13 July 2005. (c) Horizontal distribution of daily SSH (cm) calculated by the MOVE system and corrected to make the 7-day spatial mean of the daily MOVE SSH equal to that of the AVISO SSH. W1 and W2 in part (a) and the green circles in part (c) indicate the warm-core eddies. The large circles along Hai-Tang’s track in parts (b) and (c) indicate the start and end positions of the numerical integration.
