Région V: Pacifique Sud-Ouest



La Région du Pacifique Sud-Ouest est une vaste zone qui englobe l'Asie du Sud-Est et le Pacifique. Elle regroupe 24 Membres de l'OMM, lesquels sont desservis par le Bureau de représentation de l'OMM pour le Pacifique Sud-Ouest, sous la supervision du Bureau régional de l'OMM pour l'Asie et le Pacifique Sud-Ouest. Elle couvre différentes zones climatiques et est sujette à un large éventail d'impacts climatiques et météorologiques, allant des vagues de chaleur et des sécheresses aux cyclones et aux inondations. Le climat de l'Asie du Sud-Est est largement déterminé par les moussons et les alizés, tandis que le Pacifique est influencé par les cycles de La Niña et d'El Niño. La Région se situe également dans la ceinture sismique du Pacifique.

Ces 50 dernières années, la Région a subi 1 493 catastrophes, responsables de 66 951 décès ainsi que de pertes économiques à hauteur de 185,8 milliards de dollars É.-U. Les cyclones tropicaux sont la principale cause des décès dus à de telles catastrophes. La sous-région de l'Asie du Sud-Est comprend des pays comme la Malaisie et l'Indonésie, tandis que la sous-région du Pacifique se compose de l'Australie, de la Nouvelle-Zélande et de 14 petits États insulaires en développement. Ces îles sont particulièrement vulnérables en raison de leurs services météorologiques de capacité limitée.

Le réchauffement des océans et l'élévation du niveau de la mer exacerbent ces risques, en particulier dans les îles de faible altitude et parmi les populations côtières. Pour relever ces défis, l'OMM collabore avec des partenaires, dont le Bureau des Nations Unies pour la prévention des catastrophes, l'Union internationale des télécommunications, la Fédération internationale des Sociétés de la Croix-Rouge et du Croissant-Rouge et la Commission économique et sociale des Nations Unies pour l'Asie et le Pacifique, afin de renforcer les systèmes d'alerte précoce. Les rapports régionaux sur le climat, étayés par des données scientifiques et socio-économiques, contribuent à la formulation de politiques visant à renforcer la résilience face à l'aggravation des effets du changement climatique.

Ongoing projects in the region

Climate Science Information for Climate Action (CSICA)

Since October 2018, and in response to the Paris Agreement (Article 7, paragraph 7 (c)) WMO and Green Climate Fund (GCF) have partnered to provide the global community with access to new climate information, tools, and guidance to facilitate the generation and use of climate information in support of climate action decisions, recognizing the contribution and value of science-based decision-making in responding to climate change.  Some of the products developed by WMO include a methodology for Developing the Climate Science Information for Climate Action (WMO-No. 1287), data, tools and associated technical resources for enhancing the climate science basis for GCF-funded projects and activities, as well as for National Adaptation Plans (NAPs) and climate policies.  The aim of providing these products is to help all countries, in particular least developed countries (LDCs), small island developing states (SIDS) and developing countries to identify and select the most effective climate actions to address climate impacts. In doing so, the guidance can contribute to country-level decision-making and the mobilization of climate finance.The Climate Science Information for Climate Action (CSICA) initiative was officially launched in 2021 at the twenty-sixth Conference of Parties (COP 26) to the United Nations Framework Convention on Climate Change (UNFCCC) in Glasgow, Scotland. Furthermore, the GCF Board at its thirty-third Session in July 2022 adopted Decision 19 (GCF B.33/19) recognizing the results of the WMO-GCF collaboration and acknowledged the importance of scaling up the support for strengthening the capacity of all stakeholders to access, synthesize, and incorporate relevant climate science information into climate action policies, plans and investments, as well as enhancing the hydrological and meteorological systems and associated climate information services for low-carbon and climate-resilient development.Noting significant demand from countries, and high-level political support for this work, WMO is implementing the CSICA initiative through the provision of institutional coordination support, technical advisory services, capacity development and increased partnerships. 

Completed projects in the region

Intra-ACP Climate Services and Related Applications (ClimSA)

Climate extremes are placing growing pressure on water resources, food security, and livelihoods in many developing countries. The 79 Members of the Organization of African, Caribbean and Pacific States (OACPS) are among the most vulnerable, yet Member States of the OACPS have contributed least to greenhouse gas emissions.The EU-funded Intra-ACP Climate Services and Related Applications Programme (ClimSA) was established to address these challenges by enhancing the climate services value chain across the African, Caribbean, and Pacific (ACP) regions.  ClimSA has brought together eight Regional Climate Centres (RCCs), ten National Meteorological and Hydrological Services (NMHSs) from focus countries, the European Commission’s Joint Research Centre (JRC), EUMETSAT, the African Union Commission (AUC), and the World Meteorological Organization (WMO) to strengthen climate prediction, data management, and the delivery of actionable climate services.By enhancing the production, translation, and uptake of climate information, the Programme contributes directly to informed decision-making, resilience building, and sustainable development in climate-sensitive sectors. ClimSA supports these efforts through technical assistance, financial support, as well as infrastructure and capacity development.As main users of climate services and the bridge to other final users, the African Regional Economic Communities (RECs), the African Union Commission (AUC), the Caribbean Meteorological Organization (CMO) , and the Secretariat of the Pacific Regional Environment Programme (SPREP) are the focus of the programme to ensure sustainability and utilization of climate services. ClimSa Community Space 

Coastal Inundation Forecasting Demonstration Project Fiji (CIFDP-F) : Development of an Integrated Coastal Inundation Forecasting System in Fiji

The CIFDP- F is facilitating the development of efficient forecasting and warning systems for coastal inundation based on robust science and observations, along vulnerable coastal areas in Fiji. In doing so, the CIFDP-F will integrate cross-cutting scientific models into an open forecasting environment for the purpose of improving/ expanding/ developing the forecasting and warning systems for storm surges, hydrological response to heavy rainfall and Tropical Cyclone landfall on coastal areas, and other phenomena causing coastal inundation. Beneficiary groups  are mainly coastal communities in Fiji in the immediate term, through the improved performance of national institutions responsible for coastal disaster forecasting, warning, and climate adaptation planning. Every year, populations in coastal zones are impacted by coastal inundation caused by waves, including long period swell, storm surges and hydrological inundation, resulting in loss of life and damage to property. The results of this project will provide critical information to improve forecasting, warning, and evacuation planning in coastal zones.            The beneficiary sectors will include the coastal residents (end users) in agriculture, fishery, tourism and other industries, disaster managers in central and regional governments (intermediary users). In particular, improved forecasting services will serve greatly to ensure safe operation of tourism business, which is a major source of Fiji’s income. The project is divided into phases to be implemented within the period 2016 to 2020 and a total budget of USD 1.2 million, generously provided by the Korea Meteorological Administration.
