Activities
at K B C A O S:
·
Simulation
of Indonesian throughflow and its impact on Southern Indian Ocean (SIO)
and Bay of Bengal (BoB)
The Princeton Ocean Model (POM) has been used to study
the impact of Indonesian throughflow in the Southern Indian Ocean and Bay
of Bengal. POM model is being suitably modified for the Indonesian region
and surface forcing routines are being developed. Sensitivity experiments
pertaining surface wind forcing has been carried out. Impact of topographic
features on the model simulations has also been studied.
Activities
at Space Applications Center:
·
Validation
of the wave model with in-situ and satellite data.
WAM
model simulations were validated against significant wave heights and wave
period data retrieved from space-borne altimeter (Topex/Poseidon) and Indian
Ocean Buoy data.
·
Sensitivity
test of the wave model against errors and frequency of the wind forcing.
Experiments
regarding sensitivity of the model to errors in the input forcing and frequency
of the input given to the model were performed. The results of this experiments
indicate that wave model is sensitive to the input forcing with errors more than
2 m/s. Regarding the frequency of the input forcing, errors grows when the
forcing is less frequent.
·
Impact of
satellite data on wave model in extreme events.
The
wave model performance in extreme cases was also been investigated. It was seen
that in general, the wind forcing from the atmospheric general circulation model
is unable to capture the extreme wind conditions. Hence when used to drive the
wave model, under predicts the wave height. Another source of getting
high-resolution wind information is from space borne scatterometer. Using
scatterometer data, wave model is able to predict extreme wave heights correctly
in the Indian Ocean (Bhatt et al. 2002); however several places in Pacific Ocean
it underestimated the extreme wave conditions.
·
Operational
wave forecast for Indian Ocean region.
The
major objective of the project was to develop an operational wave forecast
system that can be used to forecast waves in the Indian Ocean. For this purpose,
a wave forecast system was developed by our team. This wave forecast system
implemented and validated at operational organization, Indian National Center
for Ocean Information Services, Hydrabad (INCOIS). This exercise supported our
belief that efficiency of the wave forecast is dependent on the atmospheric
model wind analysis and hence forecast capability of the wave model is up to two
days in advance.
·
Satellite
data assimilation in the wave model.
Satellite
data can be used to assimilate in the numerical models. Working in this
direction different assimilation scheme was worked out for the wave model,
including simple replacement of the space borne altimeter (ERS, Topex/Poseidon,
Jason-1) wave height and hence wave spectrum data and advanced technique of
optimal interpolation. The results of these experiments are quite encouraging. A
part of the study has been submitted to IEEE journal of geosciences and remote
sensing for possible publication.
·
Indian
ocean circulation modeling
Along
with wave modeling activity, a 2-½ layer Indian Ocean circulation model was
also installed and modified for operational usage using daily
satellite/atmospheric general circulation model wind fields. Assimilation of Sea
level data in the same model has also been carried out (Basu et al. 2003).
During
the period of my work experience I came across several scientific data formats
including NetCDF, HDF, GRIB data formats, scientific software, Programming
languages and data visualization packages.
