GROW Fine South China Sea (GFSCS) hindcast is Oceanweather's
comprehensive study of the South China Seas.
The wave model grid spacing available in GFSCS is 25-km, and shallow water effects are included through a modern third-generation physics source term formulation. A 2D hydrodynamic model (HD) was used to model storm surge, without consideration of tidal effects, on a grid of 28-km spacing.
hindcast regimes include high ranked typhoons and
monsoons selected from as long a period of history
as deemed viable for the reliable specification of
the meteorological properties of historical storms.
Therefore, tropical cyclones are included from the
period July 1946 - November 1998. Monsoons are included
within the period 1953-1997.
operational series covers 1981-2000, which is a continuous
20-year period, and is somewhat shorter than the nominal
global GROW simulation. Wind fields for the tropical
storms and the monsoons were derived by application
of Oceanweather's trademark Interactive Kinematic
Objective Analysis (IOKA) technology. For the continuous
hindcast, background wind fields are taken from the
NCEP/NCAR Global Reanalysis (NRA) Project and systematic
errors in those winds are minimized using new techniques
based on comparative analysis of NRA and QuikSCAT
satellite scatterometer winds. All reanalyzed storms
within the 20 years of the continuous hindcast (1981-2000)
were assimilated into the continuous wind fields.
The influence of Southern Hemisphere cyclones on the
wind fields in the southern part of the GFCS domain
(e.g. Java Sea) was considered for the first time
and the boundary of the 25-km grid was open to the
adjacent seas with boundary conditions supplied by
OWI's GROW global hindcast.
The products of GFSCS include,
for each site of interest, the actual simulated hindcast time series from all models
(continuous/typhoons/monsoons), wave spectra if available, and statistics. They can
be purchased together or separately.
