Guide des systèmes d’observation et de diffusion de l’information pour l’assistance météorologique à la navigation aérienne
Ce guide présente certains des systèmes d’observation existants qui sont susceptibles de répondre aux exigences pratiques de la météorologie aéronautique et donne des indications sur les systèmes que l’on juge les mieux adaptés aux différents contextes. Il préconise l’adoption, s’il y a lieu, des normes promulguées par l’OMM et l’Organisation de l’aviation civile internationale (OACI). Enfin, il aborde l’importante question du coût de la fourniture des observations en regard des avantages mesurables que l’on compte retirer d’une application donnée.
Guide to Meteorological Observing and Information Distribution Systems for Aviation Weather Services
This Guide presents some of the observing systems currently available to meet the stated operational requirements in aeronautical meteorology and provides guidance on the ones deemed most appropriate under different circumstances. Where applicable, the Guide encourages the adoption of WMO/International Civil Aviation Organization (ICAO) standards. An important issue considered is the cost of the provision of observations in relation to the expected measurable benefits to be derived from a particular application.

Comparison of different rainfall inputs in a continuous rainfall-runoff model – a case study for Argentina
Buzzella Maria Mercedes; Institute of Water Resources Management, Hydrology and Agricultural Hydraulic Engineering - Leibniz Universität, 2013Precipitation data is the main input parameter in order to simulate rainfall-runoff processes, since it is strongly dependent on the accuracy of the spatial and temporal representation of the precipitation. In regions where rainfall stations are scarce, additional data sources may be considered necessary. In this manner, remote sensing from satellite platforms has provided a satisfactory alternative due to its global coverage. Although a wide range of satellite-based estimations of precipitation is available, not all the satellite products are suitable for all regions. Most of the studies perf ...

Topics geo natural catastrophes 2012: analyses, assessments, positions
Munich-Re, 2013This report shows that the natural catastrophe statistics for 2012 were largely dominated by atmospheric events, with no catastrophic earthquakes. Due to a number of major weather-related catastrophes, including severe tornado outbreaks in the spring and a record drought in the US Midwest, the USA accounted for an exceptionally high proportion of natural catastrophes. However, Russia also experienced unusually hot, dry conditions, and vast tracts of land were devastated by wildfires.
Turn down the heat: climate extremes, regional impacts, and the case for resilience
This report focuses on the risks of climate change to development in Sub-Saharan Africa, South East Asia and South Asia. Building on the 2012 report, Turn Down the Heat: Why a 4°C Warmer World Must be Avoided, this new scientific analysis gives a more detailed look at how the negative impacts of climate change already in motion could create devastating conditions especially for those least able to adapt. It asserts that the case for resilience has never been stronger. This report demands action. It reinforces the fact that climate change is a fundamental threat to economic development and the ...

Farmers’ perceptions and adaptations to climate change in sub-Saharan Africa: a synthesis of empirical studies and implications for public policy in African agriculture: In Journal of Agricultural Science, Vol. 5, No. 4
The problem of climate change in Africa has the potential of undermining sustainable development efforts if steps are not taken to respond to its adverse consequences. This study reviews existing and available literature on farmers’ perceptions and adaptations to climate change in sub-Sahara Africa.
It is evident that the majority of farmers in sub-Sahara Africa are aware of warmer temperatures and changes in precipitation patterns. To respond to these changes, farmers have adopted crop diversification, planting different crop varieties, changing planting and harvesting dates to corres ...
Services météorologiques, hydrologiques et climatologiques: compétences requises des formateurs
Le présent document définit un cadre de compétence pour le personnel impliqué dans les activités de formation, mais il n’est pas nécessaire que chaque intervenant possède l’ensemble des compétences présentées. Toutefois, dans les conditions d’application énoncées ci-après, qui seront différentes pour chaque organisation, on s’attend à ce que tout établissement qui propose des services d’enseignement et de formation à des météorologistes ou à des hydrologistes en exercice ou en cours de formation soit doté du personnel susceptible de couvrir l’ensemble des compétences voulues.
Competency Requirements for Education and Training Providers for Meteorological, Hydrological, and Climate Services
This document sets out a competency framework for personnel involved in training, but it is not necessary that each person has the full set of competencies. However, within the following application conditions, which will be different for each organization, it is expected that any institution providing education and training services to current and future meteorologists and hydrologists will have staff somewhere within the organization who together cover all the competencies.

National Greenhouse Gas Emissions Baseline Scenarios : Learning from Experiences in Developing Countries
Xenarios Stefanos - RiceClima, 2013This report aims rather to contribute to a better understanding of the issues and challenges involved in drawing up baseline scenarios, by documenting and drawing lessons from the breadth of existing practices in a range of countries. This existing diversity is both a key asset for gradually increasing the robustness of baseline scenarios, but also the reason for a lack of comparability.
PWS, 27. Guidelines for Implementation of Common Alerting Protocol (CAP)-Enabled Emergency Alerting
The World Meteorological Organization (WMO) Public Weather Services (PWS) Programme has the primary role of assisting National Meteorological and Hydrological Services (NMHSs) to develop or enhance their capacity to deliver services to the public, media, disaster managers and responders and other users in socio-economic sectors. The PWS Programme therefore assists NMHSs in their responsibility of providing warning and alerting services for the safety of life and livelihood, and property when threatened by extreme weather events such as heavy rain, heavy snow, strong winds, heat waves and extre ...
