13. B. Review on RFSC Ha Noi’s activities
I. INTRODUCTION OF NHMS
B. Review on RFSC Ha Noi’s activities

14. B. Review on RFSC Ha Noi’s activities
Purposes of the Severe Weather Forecasting Demonstration Project (SWFDP) for Southeast Asian (SeA) and the role of Ha Noi as the Regional Forecasting Support Center (RFSC) in SWFDP-SeA
Activities in 2016: the demonstration phase

15. Purpose of SWFDP-SeA (1)
Sharing global forecast from international centers and regional forecast running from Viet Nam (both deterministic and ensemble forecasts)
Providing guidance for short range (1-2 days) and medium range (3-5 days) based on NWP products for strong wind (over 30 kts and 50 kts) and heavy rainfall (over 50mm/24h and 100mm/24h). These guidance were created by RFSC-Hanoi
NHMs joined to the SWFDP-SeA project (Laos, Cambodia, Thailand, Philippine and Myanmar as an observer) can use the SWFDP-SeA guidance to enhance their forecasts

16. Purpose of SWFDP-SeA (1)
All products have been sharing at website (password protected), including:
Global and regional forecast products (including both deterministic and ensemble)
Observations over the Southeast Asia domain: satellite data, satellite based products
1-5 days guidance for heavy rainfall and strong wind areas based on NWP products

17. Examples of deterministic products (global and regional forecasts)

18. Activities in 2016: the demonstration phase
NWP and other products
Updating GME (DWD) to ICON system (13km)
Adding regional products: WRF-ARW and COSMO
MTSAT to Himawari-8
Sharing some useful products: satellite-based precipitation estimation from SCOPE project, RMSC Tokyo/New Delhi
Collaboration
Working with RMSC Tokyo to release the guidance in case of having Tropical storm or tropical cyclone over the Southeast Asia domain
Guidance products
Providing short range and medium range guidance since Jan-2016
Issuing every 0800UTC-0900UTC from Monday to Friday

19. II. DEVELOPING TREND AND IMPLEMENTING MEASURES (2016-2025)

20. Investing in infrastructure development
Developing our station network
( ):
Surface Meteo. Stations: 454
Raingauge: 755
Radiation: 18
Hydrological Stations: 640
Marine Met. Stations: 77
Aero- Meteorological Observation
Radiosonde stations: 11
Wind-gauge by theodolite: 14
Ozone and UV :
Weather radars: 21
: Building 2 data centers, the main one in Hanoi and the backup one in Hochiminh City
In 2017: We are going to complete the infrastructure of Hanoi DC; We will implement a new Supercomputer System to run numeral weather predicting models; we will get 3 new Japanese radars for our radar network
Have no tools for compositing radar data
RECO-7 in Regional Association II, Feb 2017, Abu Dhabi, UAE

21. Building a centrelized database system
Building a centrelized database system: All data would be collected to the Center DataHub for processing, storing and sharing with other units
Our database will be redesigned with the centrelizing trend
Upgrade and build new software tools to be able to operate compatibly with the new centralized database
Changing the attitudes and awareness of our staff with the new centerlized database system, thereby changing the thinking and awareness as well as ways of organizing work and human resources, ... accordingly (This is the most difficult problem is encountered)
RECO-7 in Regional Association II, Feb 2017, Abu Dhabi, UAE

22. B. RFSC
- Updating HPC system at NCHMF in to Tflops which can help downscaling to 2-3km NWP in operation over SeA domain
- Applying the results of WMO fellowship program at ECMWF (main topic is on verification for Viet Nam) for other countries over SeA (need local data and global/regional NWP archives)
- Discuss with WMO and member of SWFDP-SeA for the next steps of RFSC and SWFPD-SeA (capabilities of Viet Nam)

23. III. Difficulties and Challenges
A. NHMS
B. RFSC

24. A. NHMS
Need more funding to carry out investment in infrastructure development.
Do not have appropriate tools to composite our present radar data
The countries in our region need to have a solution to be able to share radar data.
Research on WIGOS Metadata (OSCAR) to build applications in a centerlized database system.
RECO-7 in Regional Association II, Feb 2017, Abu Dhabi, UAE

25. B. RFSC
- RFSC’s Ha Noi need to enhance the knowledge of forecast experiences over different countries in Southeast Asian domain
- Limitation of regional NWP:
The horizontal resolution and data assimilation of local data (radar, observation)
Verification information of different countries
