Vision for improving severe weather forecasting and warning services in developing countries “NMHSs in developing countries are able to implement and maintain reliable and effective routine forecasting and severe weather warning programmes through enhanced use of NWP products and delivery of timely and authoritative forecasts and early warnings, thereby contributing to reducing the risk of disasters from natural hazards.” (World Meteorological Congress, 2007 and 2011)

Implemented through the Severe Weather Forecasting Development Project (SWFDP) “Implementation of a “Cascading Forecasting Process”, an approach that provides improved access to, and effective use by forecasters of existing and newly developed NWP/EPS products made available by advanced GDPFS Centres, national forecasting and warning services have improved significantly, with increased lead-times and greater reliability.”

(World Meteorological Congress, 2011)

WMO

Improve Severe Weather Forecasting through the “Cascading Forecasting Process” (Global to Regional to National)

Improve lead-time of Warnings

Improve interaction of NMHSs with users

Identify areas for improvement and requirements for the Basic Systems

Improve the skill of products from WMO Operational centres through feedback

SWFDP Main Goals

Global NWP centres to provide available NWP/EPS and sat-based products, including in the form of probabilities, cut to the project window frame;

Regional centres to interpret information received from global centres, prepare daily guidance products (out to day-5) for NMCs, run limited-area model to refine products, maintain RSMC Web site, liaise with the participating NMCs;

NMCs to issue alerts, advisories, severe weather warnings; to liaise with user communities, and to contribute feedback and evaluation of the project;

NMCs have access to all products, and maintained responsibility and authority over national warnings and services.

Vision for the SWFDP as an end-to-end, cross-programme collaborative activity (led by the GDPFS) “that engages all WMO programmes that concern the real-time prediction of hydro-meteorological hazards, through their respective technical commissions: from observations, to information exchange, to delivery of services to the public and a range of targeted applications/user sectors, education and training, capacity development and support to LDCs, and to the transfer of relevant promising research outputs into operations.” (World Meteorological Congress, 2011)

SWFDP Regional Centres

Challenging!

SWFDP – improving forecasts and warnings

• Severe weather: heavy rain, strong winds – High-impact focus (flash-flooding, damaging winds, near-shore

damaging waves, landslides); • Forecast range: up to day-5 (increased lead-time) • Forecasting (GDPFS), warning services (PWS) • Forecast Verification• Phase-in other developments• Training for forecasters and disaster managers

• Technological gaps: – Tropical convection, rapid on-set, localized events – Lack of forecasting tools in the very-short-range (< 12h) – Little or no radar coverage, few real-time observations – Internet-based

SWFDP – Cooperating with Research … incorporating promising research outputs into

real-time SWFDP demonstrations …

• WWRP • GIFS - TIGGE - Tropical Cyclone track;

extreme events (wind, precip, temps; soon to be near-real-time)

• Forecast Verification Research (e.g. SWFDP – Eastern Africa)

• Nowcasting Research – very short-range forecasting (< 12h; possibly SWFDP-SeAsia, SWFDP-Eastern Africa)

• Sub-seasonal forecasting (e.g. SWFDP-Eastern Africa)

• Public weather services & DRR, with SERA

DISCUSSION

WMO

Successful recipe – real benefits to developing and least developed countries

High impact, cost effective Visible operational results –

increased visibility, credibility and value of meteorological services Management framework at regional level (partnerships): collective

needs, motivation, buy-in, ownership, continuous learning

Accelerated technology transfer to less capable national centres through the “Cascading Forecasting Process”

Increased role of the regional centres in downscaling and tailoring products for practical use by NMHSs

Model/framework can be applied to any time-scales and a range of applications/user sectors

SWFDP – Lessons learnt

WMO

SWFDP – Resources Regular budget: GDPFS financially supported the SWFDP-related

events, including training, while a number of WMO Programmes (e.g. ETR, PWS, TCP, SAT, AgM, WWRP) have collaboratively provided limited funds to support expert participation at some of the SWFDP-related meetings

Support from advanced global centres that provide NWP/EPS and satellite-based products, and the backbone roles played by the regional centres are critical components for the implementation of the SWFDP, which represent in-kind contributions by WMO Members

Extra-budgetary funds from WMO Members, and donor agencies (e.g. World Bank, etc.)

Staff: DPFS (responsible for the overall project), with the collaboration of PWS and AgM
