Regional Climate Outlook Forums
A Regional Climate Outlook Forum is a platform that brings together climate experts and sector representatives from countries in a climatologically homogenous region to provide consensus based climate prediction and information, with input from global and regional producing centres and National Meteorological and Hydrological Services, with the aim of gaining substantial socio-economic benefits in climate sensitive sectors.
Ocean, climate and weather: the role of the World Meteorological Organization
When it comes to the weather, most of us think only about what is happening in the atmosphere. If we ignore the ocean, however, we miss a big piece of the picture: covering some 70 per cent of the Earth’s surface, the ocean is a major driver of the world’s weather and climate. The ocean is also a major driver of the global economy, carrying more than 90 per cent of world trade and sustaining the 40 per cent of humanity that lives within 100 km of the coast. Recognizing this, national weather agencies and researchers regularly monitor the ocean, model how it affects the atmosphere and deliver m ...

Weather, Climate and Hydrological services: how WMO supports the 2030 agenda for sustainable development
Weather, climate and water can either disrupt sustainable development or advance it. The providers of weather, climate, hydrological, marine and related environmental services therefore have a critical role to play in assisting countries to implement the 2030 Agenda and the Sustainable Development Goals (SDGs). High-quality meteorological services empower decision-makers to better manage agriculture, public health, water resources, energy production, transportation and other sectors that are critical for national development.

GAW Report, 226. Coupled Chemistry-Meteorology/ Climate Modelling (CCMM): status and relevance for numerical weather prediction, atmospheric pollution and climate research
Online coupled meteorology atmospheric chemistry models have undergone a rapid evolution in recent years. Although mainly developed by the air quality modelling community, these models are also of interest for numerical weather prediction and climate modelling as they can consider not only the effects of meteorology on air quality, but also the potentially important effects of atmospheric composition on weather. This report provides the main conclusions from the Symposium on “Coupled Chemistry-Meteorology/Climate Modelling: Status and Relevance for Numerical Weather Prediction, Air Quality and ...

Climate Services for Supporting Climate Change Adaptation : Supplement to the Technical Guidelines for The National Adaptation Plan Process
World Meteorological Organization (WMO) ; Global Framework for Climate Services (GFCS) - WMO, 2016 (WMO-No. 1170)Because of the current and projected impacts on climate due to the high levels of greenhousegas (GHG) emissions, adaptation is a necessary strategy at all scales in a changing climate. At its 17th session, the Conference of Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC) established the National Adaptation Plan (NAP) process as a way to facilitate effective adaptation planning in Least Developed Countries (LDCs) and other developing countries. The four key elements that need to be undertaken in the development of NAPs are: Laying the groundwork and addressin ...
WMO Statement on the status of the global climate in 2015
The year 2015 will stand out in the historical record of the global climate in many ways. Modern records for heat were broken: 2015 was a record warm year both globally and in many individual countries. Heatwaves were extremely intense in various part of the world, leading to thousands of deaths in India and Pakistan. Record extreme precipitation led to flooding that affected tens of thousands of people across South America, West Africa and Europe. Dry conditions in southern Africa and Brazil exacerbated multi-year droughts. The influence of the strong El Niño that developed in the later part ...

Climate Services for the Energy Sector: A New Priority Area for the GFCS
Energy systems are the engine of economic and social development. Their investments represent a sizeable portion of a country’s GDP. Indeed, energy is essential to practically all aspects of human welfare, including access to water, agricultural productivity, health care, education, job creation and environmental sustainability. Furthermore, energy sector emissions, such as CO2, account for the largest share of global anthropogenic greenhouse gas (GHG) emissions. Emissions reduction targets under the UN Framework Convention on Climate Change (UNFCCC) are expected to significantly increase dema ...

WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.11: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2014
The latest analysis of observations from the WMO Global Atmosphere Watch (GAW) Programme shows that the globally averaged mole fractions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2014, with CO2 at 397.7±0.1 ppm, CH4 at 1833±1 ppb[2] and N2O at 327.1±0.1 ppb. These values constitute, respectively, 143%, 254% and 121% of pre-industrial (1750) levels. The atmospheric increase of CO2 from 2013 to 2014 was close to that averaged over the past 10 years. For both CH4 and N2O the increases from 2013 to 2014 were larger than that observed from 2012 to 2013 and ...
