Forecasters' Overview of the Middle East
This lesson provides an introduction to the Middle East for Navy meteorologists. It focuses on the major aspects of synoptic and mesoscale weather patterns, hazards to aviation and maritime operations, geography, oceanography, and climatology. The “Geography” Unit covers major political boundaries, cities, ports, topographical features, rivers, and seismicity. The “Oceanography” Unit includes major bathymetric features, mean sea surface temperature, vertical temperature profiles, salinity and velocity, ocean currents, and tidal ranges. The “Climatology” Unit covers the seasonal climatology of ...
Leveraging the Best Available Science for Increased Effectiveness of Climate Finance
Effective results from climate finance require evidence- and science-based information on the state and behavior of the Earth’s atmosphere, its interaction with the oceans, regional climates, and the resulting distribution of water resources. The high demand for such information, however, has led to a fragmented flow of internationally-funded projects that lack operational linkages with broader hydrological and meteorological systems and national-regional-global integration. To address this, the World Meteorological Organization (WMO) and the Green Climate Fund (GCF) have established an innova ...
Using Climatology in Forecasting Convection in West and Central Africa
This case-study lesson provides an opportunity to apply the information in the ASMET lesson “Satellite-Derived Climatology Products for Monitoring Convection Over West and Central Africa” to a case that occurred over West and Central Africa in June 2014. It demonstrates how to integrate climatology information with satellite, global instability indices (GII), and NWP data when convection is forecast to occur.
The Sahel Drought Mechanism: insights from two contrasting extreme events
The Sahel drought mechanism: insights from two contrasting extreme events during boreal summer July-August-September (JAS) is investigated in this study using the standardized precipitation index (SPI). Empirical orthogonal function (EOF) and composite analyses were deployed in this study, where the global precipitation climatology center (GPCC) rainfall data is used. The SPI shows large widespread decreasing rainfall trend in the Sahel in the mid-1980s; thereafter, Sahel rainfall have recovered somewhat through the late 1990s, even though the drought conditions have not ended in the region. A ...
Interannual variation monthly rainfall from May to August associated with large-scale circulation anomalies over south coast of West Africa
The southern coastal region of West Africa (SCWA) is located between 40N-80N latitudes and 100W -50E longitudes near the equator in the northern Hemisphere, the south and west are respectively equatorial and West Atlantic Ocean, and it is consisted to seven countries (Sierra Leon, Liberia, Cote d’Ivoire, Ghana, Togo, Benin and Nigeria). The rainy season starts from spring to the summer, mainly from May to October. The rainfall is very important for southern coastal of West Africa region which their economy and food supply are highly dependent on agricultural production. Understanding of previo ...
Satellite-Derived Climatology Products for Monitoring Convection Over West and Central Africa
A weather forecaster’s knowledge of climatology is important to the success of a forecast, especially where convection is involved. That’s particularly true over Central and West Africa where convection has a strong diurnal cycle and usually develops over particular geographic regions and during specific time intervals. The lesson describes satellite-derived cloud climatology products and several global instability indices, all of which can be integrated with other products to forecast convection. Although the lesson uses examples of climatology products from specific months, it makes the full ...
Forecasting Heavy Rains and Landslides in Eastern Africa
Good rainfall draws many people to settle across the eastern Africa highlands for farming and other businesses. However, factors such as steep terrain, logging, livestock grazing, agriculture, and construction, have increased erosion and contributed to less stable slopes. These factors can lead to devastating landslides and mudslides, especially during episodes of very heavy rain. Forecasting and monitoring heavy rainfall is challenging, especially in mountainous regions that have few surface observations. This make satellite data critical for meteorologists and hydrologists forecasting for th ...

Big data for climate change and disaster resilience: realising the benefits for developing countries
This synthesis report explores the opportunities, challenges and required steps for leveraging the new ecosystem of Big Data to monitor and detect hazards, mitigate their effects, and assist in relief efforts. Ultimately the goal is to build resilience so that vulnerable communities and countries as complex human ecosystems not only ‘bounce back’ but also learn to adapt to maintain equilibrium in the face of natural hazards.

Disaster Risk Reduction for Resilience and Sustainable Development in the Arab Region
This brief gives an overview of the disaster trends and challenges across the Arab region.
There is a special emphasis on infrastructure, informal settlements, climate change, and cross-cutting issues such as governance, inclusiveness, decentralisation and legislation. The report also provides an analysis of proposed Sustainable Development Goals (SDGs) and Targets from an Arab Perspective.
As introduction is given to the issues around disaster risk reduction (DRR) in the Arab region. The main trends and challenges in DRR and reliance building are identified, spec ...

Migration and natural resource scarcity within the context of climate variability in West Africa
Drawing from research in rural north-western Benin, this policy brief looks at the effect of migration on the in-land fisheries subsector.
It emphasizes the need for effective participation of all stakeholders in the management of natural resources to improve livelihoods in the region facing population growth and climate variability.
The brief highlights that migration – internal and international – is an important feature of the social lives of people across West Africa. While movements within the subregion are generally due to complex and multi-causal factors, n ...

Can green growth really work and what are the true (socio-) economics of climate change?
Hoffmann Ulrich - United Nations, 2015This paper argues that growth, technological, population-expansion and governance constraints as well as some key systemic issues cast doubt ‘green growth’ hopes.
It argues that such an evolutionary (and often reductionist) approach may well not be sufficient to cope with the complexities of climate change. It may rather give much false hope and excuses to do nothing really fundamental that should bring about a turn around on global GHG emissions.
The paper argues that climate change calls into question the global equality of opportunity for prosperity and is thus ...

Potential impact of climate and socioeconomic changes on future agricultural land use in West Africa: In Earth Syst. Dynam. Discuss., 6
Copernicus Publications, 2015This study compares the contributions of climate change and socioeconomic development to potential future changes of agricultural land use in West Africa.
It uses a prototype land use projection (LandPro) algorithm which is based on a balance between food supply and demand, and accounts for the impact of socioeconomic drivers on the demand side and the impact of climate-induced crop yield changes on the supply side. It considers the impact of human decision-making on land use.
The paper argues that without agricultural intensification, the climate-induced decrease ...
