PERGOS - Persian Gulf MetOcean Hindcast Database
PERGOS is Oceanweather’s (OWI) and DHI's new comprehensive metocean study of the Gulf. It is based on hindcast of a continuous 20 year period (1983-2002) and 100+ storm events
Deliverables include
- Return-period extremes of wind speed, wave height/period, water level and currents
- Fatigue and operability data expressed as monthly and annual frequency of occurrence tables.
- Time series of wind, waves, water levels and currents are provided for 100+ storm events and the continuous 20 year period 1983-2002.

PERGOS utilizes hindcast models of higher resolution and more powerful physics than the previous studies for the Gulf region. The wind and wave hindcasts were all made with basin-wide grids of spacing .0625 degrees in latitude and longitude (7 km), nested within coarser grid systems covering the Gulf of Oman and the Arabian Sea. 2-D water levels (including surge and tide) and currents have been run with DHI’s MIKE 21 flexible mesh model using a mesh resolution better than 7 km. The wave model incorporates third-generation physics (OWI3G version 52, half friction). All hindcast time series are available in either OWI’s OSMOSIS format (for current licensees of OSMOSIS) or ASCII.
