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.

Improve collaborative working and relationships between NHMSs
Provide feedback to global centres on the performance of their models
Capacity development
Disaster risk reduction
Climate change adaptation (GFCS)
Socio-economic sectors (AeM, AgM, etc)

SWFDP Development and Implementation: a 4-step cycle
Establish regional partnerships Regional management teams; focus on forecasting and warning services of meteorological-related hazards
Plan and develop of prototype demonstration project
Regional project-specific IP for which the management team is accountable. IP describes team members’ responsibilities, project activities and milestones (typically for 12-18 months)
Implement demonstration project Tracking, continuously evaluation, training and reporting
Broaden and sustain successful prototypes (return to step 1)
Under the Guidance of the Steering Group of the SWFDP

TrainingFunded by NZ Ministry for the Environment
Tropical meteorology and climatology, “why do we need ensembles?”, how to interpret NWP from different centres. 3-5 days per country.
Aimed at a broad base of forecasters. No equations. More time spent on exercises than on lectures.
“DRR Day” – practical exercises involving outside agencies.

Nice theory, but how does it work in reality?
Here’s one example:Background: Kiribati is a participating country in the SW Pacific SWFDP. It sits either side of the equator. It is made up of 32 low-lying atolls; most of it is <2 metres above sea level.
Large Waves are the most significant weather threat to Kiribati.

• Further internal discussion• Application of local
knowledge• Contact Wellington/Fiji if
needed?

“Special Weather Bulletin” issued
Contact relevant government departments, ports authority etc.Deal with media
This is really down to the individual country – they know the structures and local conditions
Monitor event with new guidance; respond to official/public/media enquiries
Feedback after the event. Format of warning? Enough time to prepare? Accurate?

Consider Tropical Cyclones Consider Tropical Cyclones Eline (2000) and Favio (2007)Eline (2000) and Favio (2007)
(both equivalent to Cat 4 hurricanes ~220 km/h winds)(both equivalent to Cat 4 hurricanes ~220 km/h winds)
Doc Ref no: FCAST-PRE-SWFDP-20131113-001.1
• TC Eline 2000 Mozambique:– 700 deaths, 4.5 million affected – Mozambique was not prepared from a DRR perspective– Massive international rescue and support
• TC Favio 2007 Mozambique:– 29 deaths, 285000 affected– Warnings issued days in advance– Disaster management infrastructure mobilized– Communities prepared in prior training were
successfully evacuated within 2 days
• How did improved EWS through SWFDP contribute to this success for TC Favio?
![Page 24: WMO The WMO Severe Weather Forecasting Demonstration Project – bringing the benefits of leading NWP to developing countries Ken Mylne Chair DPFS (Data-processing](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649da05503460f94a8c00b/html5/thumbnails/24.jpg)
Case Study: Tropical Cyclone Favio Case Study: Tropical Cyclone Favio 20-24 Feb 200720-24 Feb 2007
• TC Favio caused widespread damage over Mozambique and Zimbabwe
• The consistency of model forecasts provided confidence to RSMC Pretoria to issue guidance to NMCs on potential landfall and movement 5 days in advance
• The model forecast proved to be quite accurate with landfall at Vilancoulos, moving to Eastern Zimbabwe
![Page 25: WMO The WMO Severe Weather Forecasting Demonstration Project – bringing the benefits of leading NWP to developing countries Ken Mylne Chair DPFS (Data-processing](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649da05503460f94a8c00b/html5/thumbnails/25.jpg)
Impact of Tropical Cyclone Favio
Doc Ref no: FCAST-PRE-SWFDP-20131113-001.1
• In both Mozambique and Zimbabwethe NMCs agreed with the guidance products and issued warnings 5 days in advance to disaster management departments
• In Mozambique: – Provinces were put on alert levels
2 - 3 days in advance– The public responded well and major
loss of live were prevented
• In Zimbabwe:– Public received early warnings by radio,
TV and newspapers 5 days in advance
![Page 26: WMO The WMO Severe Weather Forecasting Demonstration Project – bringing the benefits of leading NWP to developing countries Ken Mylne Chair DPFS (Data-processing](https://reader036.vdocuments.us/reader036/viewer/2022062314/56649da05503460f94a8c00b/html5/thumbnails/26.jpg)
EvaluationEvaluation
• Since Eline in 2000 there was a dramatic improvement in the entire DRR system in Mozambique– including EWS through SWFDP
• Question: How much of the savings of human lives can really be directly attributed to SWFDP?– SWFDP definitely lead to earlier warnings issued which
resulted in earlier evacuations

WMO
The Future - Expansion of SWFDP to a global Programme to Strengthen Operational Centres
Expansion of the SWFDP towards global coverage (3 development and demonstration phases)
Transition to sustainable operations (phase 4)
It requires a programme office to support non-operational activities and development of new SWFDP regional projects

SWFDP Role in HIWeather Project
Testbed for new forecast products and capabilities Feedback and verification (subjective?)
SERA work in building PWS requirements and relationships
But please remember… Regional Centres and NMHSs have very limited
resources Focus must be on operational work
Issuing warnings Developing PWS user relations and response plans Staff and user training Sustainability
