Theme I
Improvement of Global
Analysis-Forecast System
Scientific Issue:
·
Realistic
representation of the global circulation in analysis and model forecast fields
are of prime importance
·
For
good medium range forecast, the short range and the extended range forecast
from the model have to be also good. We have to work in this direction by
taking care of different steps like Quality Control, analysis, forecast model
and Diagnostics
·
Proper
representation of tropical monsoon environment in a global model is a challenge
to the scientific community worldwide. Joint work of mutual interest will lead
to progress in understanding and skill upgradation
Plan
of Action : NCEP and NCMRWF
·
Radiance
and rainfall assimilation for global SSI and ETA assimilation system code will
be made available through FTP. NCMRWF scientists can make themselves familiar
with it. If funding is available scientists can be sent for long period (one
year) to work on some scientific problems identified by NCEP on
global and ETA analysis system
and gain expertise in that process. NCMRWF scientists can participate in grid
point version of 3-D variational system of NCEP under testing.
·
NCEP is exchanging global analysis/forecast
with other centers. NCMRWF can participate in it, and exchange it’s
analysis/forecast files through FTP This will help in inter-comparison and
verification of output and learn the
strengths and weaknesses over different regions / seasons.
·
NCEP is deriving
surface wind, TPWC and rain rate
from SSM/I using it’s own neural network based algorithm (OMBNN3). The products
may be made available through FTP in real time.
·
Current
Quality control code for different type of conventional and satellite data from
NCEP will be made available to NCMRWF
·
NCMRWF scientists can put new physics to NCMRWF
T170 model from the current NCEP global model and provide feedback to NCEP on
performances
·
New
Gravity wave drag code can be used from NCEP model. 30 seconds orography may be
incorporated in NCMRWF model
·
NCMRWF
can try to put new radiation code AER in it’s global model and provide input to
NCEP. Neural network based radiation if called every time step will be good.
·
NCEP
has plan to test 35 day forecast using global model. NCMRWF can participate and
do evaluation for the Indian region and compare with NCMRWF extended range
forecast from global model.
·
Exchange
information on statistical interpretation of model output and automation of
local forecasts.
·
Joint
collaborative proposals with NCEP will be submitted for funding under Indo-US
Forum to carry out research and development works of mutual interest.
Theme
II
·
Intraseasonal
Variability of the summer monsoon
(e.g., role of the MJO, the break and revival of the monsoon)
·
Surface
heterogeneity and convection (e.g., land use, heavy rainfall events)
·
Orographic
effects on the semi-permanent features of the monsoon (e.g., LLJ, monsoon
trough)
models
·
Mesoscale
assimilation with special data sets in the Indian region (e.g., satellite,
radar, field experiment data)
·
Real
time prediction and model evaluation (e.g., monsoon depression, heavy rainfall,
western disturbances and severe local storms)
·
Prediction
of track and intensity of tropical cyclones (e.g., initialization, re-intensification
of land-falling cyclones)
·
Sensitivity,
validation and improvement of physical parameterizations (e.g., cloud-resolving
models, coupled land air-sea models, field experiments)
