About Research Forecasting MetOcean Studies News Current Marine Data

PERGOS-2 is Oceanweather's comprehensive metocean study of the Gulf. As such, it represents Oceanweather's long history of regional specific studies carried out in this basin within the past 35 years. Such studies have essentially set the standard for metocean design data.

PERGOS-2 utilizes hindcast models of high resolution and powerful physics. The wind hindcasts were developed using Oceanweather's latest and most refined surface wind field kinematic reanalysis technology. The winds are integrated on a basin-wide fine mesh ocean response wave model nested within coarser grid systems covering the Gulf of Oman and the Arabian Sea. Currents and 2-D surge have been modeled for the storm and continuous hindcasts on fine mesh grids. All hindcast time series are available in ASCII format.

The historical storm population of PERGOS-2 consists of 155 events spanning the years 1961-2018. The continuous hindcast covers multiple decades (1979-2018) to ensure that it simulates the recent and current climate.

PERGOS-2 may be licensed in the form of model output time series only, derivative normals and extreme statistics only, or a combination of both.

  • Time series of winds, waves, surge and currents (with and without tides) are provided for hindcasts of storm and continuous hindcasts.
  • Return-period extremes of wind speed, wave height and period, and surge and 2-D currents are derived in both omni-directional and sector stratified form.
  • Fatigue and operability data expressed as monthly and annual frequency of occurrence tables of wind speed by wind direction, wave height by wave period and direction, and exceedance and non-exceedance duration statistics for wind speed and wave height.
  • Final Report with block specific extremes and sample normals.
