PERGOS3
is Oceanweather's latest comprehensive metocean study
of the Gulf. As such, it represents Oceanweather's long history of regional
specific studies carried out in this basin since the 1990s, including
the two previous iterations aptly named PERGOS and PERGOS-2.
Such studies have essentially
set the standard for metocean design data.
PERGOS3
utilizes a coupled wave (SWAN) and hydrodynamic (ADCIRC) model.
The new PERGOS3 background winds employ Oceanweather's latest kinematic analyses
and previous storms from PERGOS and PERGOS-2 were reviewed and
revised as needed. The winds are interpolated onto an ultrafine
finite-element grid that covers the entire Gulf and extends into the Gulf of
Oman with an average <0.5 km grid spacing closest
to shore. The ADCIRC model passes the wind forcing and water levels
to the SWAN model while the SWAN model passes the radiation stresses
to the ADCIRC model throughout the entire hindcast simulation with
results archived at over 250,000 grid points for every hour.
The PERGOS3
archive consists of a 1-hour continuous hindcast spanning the years 1960-2024
to ensure that it simulates the recent historical and current climate.
All hindcast time series are available in ASCII format.
PERGOS3
may be licensed in the form of model output time series
only, derivative normals and extreme statistics only,
or a combination of both.
