READINESS for FDP
Only about half of the centers provided input in real time during the
latest practice period.
As anticipated, difficult for RosHydromet’s forecasters to use
products from the foreign numerical prediction systems.
Time is running fast, the new products will have to come online very
quickly.
Another test period in September and October… chance of training
with new systems.
Team of scientists to advise in real time, but difficulties associated
with language and with the forecasters tight time schedule
11

WWRP
POSSIBLE SCIENTIFIC OUTCOMES (RELATED to
MODELING)
Impact of resolution, physics
Impact of surface characteristics (e.g., snow)
Products of interest: wind gusts, visibility, snow-rain ratio, precip type
Prediction / modeling of clouds and precipitation in general (interest
in precipitation types)
Complementarity of 7-km ensemble systems and higher-resolution
deterministic systems for this type of region.
Calibration of ensembles.
A multi-model ensemble.
Data assimilation: performance of a few approaches, e.g., nudging
vs 3DVAR.
After the Games: Follow-up in terms of research/analysis of
outcomes? Some common write-up of outcomes??

Grey zone project
 WGNE project endorsed by 2011 JSC: subgroup from WGNE, WG-
MWFR, GCSS to jointly set up idealized grey zone experimentation
 Run several LES systems at several 100m resolution as “truth”,
make model simulations at stepwise progressively coarser
resolutions throughout grey zone range, for different models. 1- and
3D- analysis of outcome.
 Set up basic experimental framework and gain participants for initial
“simple” extratropical case of cold air outbreak over sea, in 2011-
2012. Study evolution of convection and BL for this case. Later
extend this framework and modelling community to other cases,
including e.g. deep convection in tropics, open cell convection over
land.
 Status: Expressed interest by 10+ modelling groups. Case tested
with 2 CRM’s and fully defined and released to LAM/global
modellers by Dec 2012. Regional and global model runs started in
2013.

Various other activities
 On-line LAM EPS training for duty forecasters in cooperation with
EUMETCAL (March 2012)
 Activities aiming at promoting international exchange of
observations relevant for mesoscale DA for research (e.g.
Hymex) and operational purposes
 Tigge-LAM: Start with LAM EPS archive at ECMWF in GEOWOW
 Active in definition of EUMETNET/SRNWP EPS and Nowcasting
programmes

WWRP
Radar volume data: critical source for mesoscale DA
but problematic access for NWP across borders
Much operational evidence for positive impact of radar volume (reflectivity
and wind) data. Relative importance of radar data vs other obs especially
large for fine-scale models
For smaller countries, access of radar data across borders is highly
problematic: data policy, data exchange and data format differences are
limitations
OPERA ODIM data model very helpful, but doesn’t solve all problems (yet).
Large coverage of model domain by even spread of radars appears critical
to timescale of positive impact!

Spectral decomposition Varian
ce
spectr
um
 Higher reduction of variance error for wavelengths corresponding to
the higher values of variance spectra
 For wavelengths shorter than :
 200 km, only radar and plane measurements for temperature ( GPS
for specific humidity) contribute to the variance reduction
 100 km, the variance reduction reach only 5% of the error variance
and it is only provided by radar observations

WWRP
Mode-S observations:
a high-density data source of interest
Observations made by every aircraft for
ATC: ff,ddd straightforward to derive, T with
some approximation
Quality after QC/BC: comparable to radio
soundings for ff,ddd, slightly worse for T,
but very dense dataset!
Impact studies: significant positive
impact!
Data preprocessing/quality control/bias
correction algorithms available
Discussions with several ATC centers to
arrange real-time data provision (latency:
<10min) for a large European area.
Intention: formal arrangements for free
availability (at zero cost) of these data to
NMS’s for official duty. Eurocontrol
Maastricht data available for NMS’s via ftp
from July 2013 on.

Data policy
International registered participants are regarded as the participants of
“Social System Reformation for Adaptation to Climate Change”, Strategic
Funds for the promotion of Science and Technology (JST/MEXT), and
follow the same data policy as for the domestic scientists:
Quick-look data are open on-line (Reproduction is prohibited)
X-NET data become open after two year of observation
JMA and MLIT data will become open (need agreement)
As for other special observation data, the observers keep their priority.
these data are basically offered individually by mutual agreement
between observers and users
Data taken by the most advanced systems described in A3.2 (C-band
polarimetric radar, KU-band radar, and dense AWS network) are in
principle not open for international participants.

Aim: enhance use of LAM’s and LAM EPS’s in TC forecasting
Proposal: extend approach followed in existing TL-FDP to LAM’s.
Objectives of existing TL-FDP
To enhance the ability of forecasters to issue timely and accurate
typhoon forecasts and strengthen the ability of decision-makers to
analyze and determine the accuracy of typhoon forecasts
To demonstrate the performance of the most advanced typhoon
forecasting technique in the world
To assess the WMO-TLFDP’s impacts on enhancing the typhoon
forecast service as well as its social and economic benefits
To promote the implementation of the most up to date forecast
technique for landfall typhoons in typhoon-affected Members of WMO
To enhance the capability of forecasting typhoon landfall for the
“Shanghai MHEWS” to enable SMS to provide enhanced typhoon
forecast service during Shanghai Expo 2010
Proposal exchange/verification of LAM TC
products

Operational TC forecast verification practice in the western
North Pacific region
The current operational status of TC forecast
verification has been analyzed on the basis of an e-
mail survey covering all the Members of
UNESCAP/WMO Typhoon Committee
Main conclusions are
Significant efforts have been focused on the verification
of TC track forecast guidance by operational forecast
agencies in the region (mostly global models)
Only a few verification products are available for
probabilistic forecasts from EPS
Verification of TC intensity, precipitation and high wind
forecasts are lacking sufficient attention in the region
The international exchange of TC forecasts from
regional models deserves to be paid more attention
(intensity & precipitation).
40

WWRP

WWRP
A proposal to extend TC exchange and verification
to LAM’s
It is proposed to explore the definition of an FDP aiming at the extension of TC
international exchange and verification, as started in TL-FDP for TC tracks, to
LAM and LAM EPS forecasts of TC intensity and precipitation, later possibly
also wind. Start with existing models, NW Pac?
Aim: Improve operational fc capability of TC intensity, precipitation to +48h:
• Set up guidelines and establish data center for exchange of (existing) global, LAM and
LAM EPS TC products
• Evaluate models’ performance for TC intensity, precipitation
• Gain understanding of physical mechanisms underlying different model performance,
performance and impact of different DA systems, and impact of different observing
systems on fc quality
• Propose skillful multi-model consensus fc scheme
• Establish fc range in which the LAM model output is useful
• Enhance application of advanced LAM’s and LAM EPS’s
The JSC is requested to endorse an investigation into the viability of such an TL-
LAM FDP.
