Development of SWFDP – Southeast Asia

Planning Information

NMHS of ______CAMBODIA______

(to be completed by Cambodia, PDR Lao, Thailand, Viet Nam)

Introduction

The outcomes of the Workshop on Severe Weather Forecasting Demonstration Project (SWFDP) Development for Southeast Asia, held 2 - 5 February 2010 in Ha Noi, Viet Nam hosted by National Hydro-Meteorological Service of Viet Nam, requested the participating NHMSs to provide information to assist in the planning of a SWFDP project. Please see the final report of the meeting, in “Section 6 – Planning a RA II Regional Subproject”, in particular paragraph 6.6.3.

The following information is designed to assist the participating NMHSs to provide the required information.

A - NMCs to prepare a list of forecasting and warning products required

1. Data and products from global product centres:

  • Current high-resolution deterministic NWP fields (out to 5 days)
  • Current probabilistic forecast fields (max lead-time available)

2. Data and products from regional centres:

  • Current deterministic limited area model fields (out to 2 days)
  • RSMC Severe Weather Forecasting Daily Guidance (to be determined for the Implementation Plan)

See details in the SWFDP – Guidebook (pp 9-11), at:

B –NMCs to provide all warning criteria currently used

The following table is used to gather the information. NMHSs should include all hydro-meteorological hazards for which it issues warnings or alerts. Please enlarge the table as required, to include all these hazards.

Hazard
e.g. heavy rain / Description
e.g. season, region / Warning Criteria
e.g. 100 mm/24h / Notes
e.g. general public
heavy rain / rainy season, Cambodia / 80-100mm/24h / general public
thuntherstorm / rainyseason, Cambodia / gust wind 10-15m/s / general public
river flood / rainy season, Cambodia / 0,5-1,5m of water level compare with the river bank / general public
flash flood / rainy season, Cambodia / ranfall >100mm/24 / general public
Tropical Storm / rainy season, Cambodia / the track storm close to central and south Vietnam coastal line / general public

C – NMC to provide information on Internet access capability

Please reply to the following questions:

1. Does your NMC access image products from global products centres, such as JMA, ECMWF, etc.? Please list a few sample images and provide the names of the sites.

1-JMA, satellite images

2-tropical cyclone informantion

3-Tropical Cyclone track map by Hongkong

4- NOAA satellite and information Services

2. Does your NMC download numeric files (e.g. GRIB) from other centres? Please provide the name of a file and provide the name of the site.

1-JMA, mape image of JMA GRIB data

2-Global upper level map

3-FNMOC, global model tropical area

4-Southeast Asia model

  1. What is the Internet access speed your NMC normally have (Mbps)? Do the forecasters at your NMC consider their Internet access “slow”, or “ok”? Do the forecasters rely on the Internet as essential forsevere weather forecasting at your NMC?

-256kbps, I think, it is ok, but sometime slow

- they rely on the Internet as essential for severe weather forecasting at my NMC.
