Guidelines on Ensemble Prediction Systems and Forecasting
Ensemble Prediction Systems (EPS) are numerical weather prediction (NWP) systems that allow us to estimate the uncertainty in a weather forecast as well as the most likely outcome. Instead of running the NWP model once (a deterministic forecast), the model is run many times from very slightly different initial conditions. Often the model physics is also slightly perturbed, and some ensembles use more than one model within the ensemble (multi-model EPS) or the same model but with different combinations of physical parameterization schemes (multi-physics EPS). Owing to the cost of running ...

Science Document: Best Practices on National Drought Management Policy
WWRP, 2012-1. Recommended Methods for Evaluating Cloud and Related Parameters
World Meteorological Organization (WMO) ; WWRP/WGNE Joint Working Group on Forecast Verification Research (JWGFVR) - WMO, 2012Cloud errors can have wide-reaching impacts on the accuracy and quality of outcomes, most notably, but not exclusively, on temperature. This is especially true for weather forecasting, where cloud cover has a significant impact on human comfort and wellbeing. Whilst public perception may not be interested in absolute precision, i.e. whether there were 3 or 5 okta of cloud, there is anecdotal evidence to suggest strong links between the perceptions of overall forecast accuracy and whether the cloud was forecast correctly, mostly because temperature errors often go hand-in-hand. It is therefore ...

JCOMM Technical Report, 59. Proceedings of the third International workshop on advances in the use of historical marine climate data
Marine surface observations—which represent a vital component of the Global Climate Observing System (GCOS)—are key to understanding global climate, including its variability on time scales ranging from sub-daily to weekly to centuries. Prior to 1970, ships were almost the only source of observations. In the modern era, sensors deployed on ships, moored and drifting buoys, aircraft, and Earth Observation (EO) satellites all provide surface measurements of many different variables. The Third International Workshop on Advances in the Use of Historical Marine Climate Data (MARCDAT-III) was hosted ...
GAW Report, 202. Workshop on Modelling and Observing the Impacts of Dust Transport/Deposition on Marine Productivity
In this report we evaluate the state-of-art knowledge and uncertainties regarding the deposition of dust on the ocean and its mineralogical composition provided by models and measurement datasets. Global climate models were recently intercompared by Huneeus et al. (2011) using results from the AEROCOM model intercomparison. The deposition calculations from these global models are frequently used as input for biological productivity calculations. A model measurement comparison (Huneeus, 2011) shows that global models do reproduce the observed data over several orders of magnitude. However, the ...

On the Reprocessing and Reanalysis of Observations for Climate
The long observational record is critical to our understanding of the Earth’s climate, but most observing systems were not developed with a climate objective in mind. As a result, tremendous efforts have gone into assessing and reprocessing the data records to improve their usefulness in climate studies. Many challenges remain, such as tracking the improvement of processing algorithms. Reanalyses have fostered significant research, yet reliable global trends in many physical fields are not yet attainable, despite significant advances in data assimilation and numerical modeling. Communication o ...
Flood Management Tool Series, Technical Document, 12. Management of Sediment-Related Risks
Sediment-related disasters, which are caused by debris flows, slope failures and landslides, have different characteristics from water-related disasters. That is, disasters sites, timing of occurence, and hazard levels are difficult to predict accurately. This Tool explains practical approaches of identifying debris flows and landslides areas and introduces good practices of mitigation measures to minimize human loss. For example, disaster prevention maps containing hazard areas, sage refuges and evacuation routes are as essential and effective means as flood hazard maps.
Flood Management Tool Series, Technical Document, 11. Flood Emergency Planning
This tool provides basic information on preparation and implementation of flood emergency management, which breaks down into three stages: preparedness, response, and recovery. By reducing exposure to flooding at each stage, flood emergency management contributes to flood risk reduction, which is an important objective of Integrated Flood Management. To this end, flood hazard maps help users understand hazard information through the process of planning, preparing and responding to flood. Emergency exercises (e.g. role playing drill) also strengthen stakeholders’ capacity to smoothly conduct em ...
Flood Management Tool Series, Technical Document, 10. IFM as an Adaptation Tool for Climate Change: Case Studies
This Tool introduces strategies for climate change adaption and implementation of the strategies in the context of flood management. Nine case studies are extracted from the following countries and a regional organization, namely US, UK, France, Germany, Netherlands, Japan, China, South Korea, and EU. The adaptation strategies are described especially from the point of flood risk assessment. Based on the projected impacts of climate change, each country formulates their own adaption measures and designates responsible agencies for their implementation.
Flood Management Tool Series, Technical Document, 05. Reservoir Operations and Managed Flows
This tool aims to provide guidance for reservoir operations and managing flows that optimize the benefits from ecosystems in the flood plains and socio-economic activities on those. It provides guidance on the issues that need to be addressed in designing and operating reservoirs to meet the requirements of various users and uses along with the ecological needs . The tool highlights various aspects of reservoir operation and discusses possibilities how flows can be managed successfully to minimize their adverse impacts. As this tool exists in the second edition, it has been revised in order to ...
IOM Report, 107. WMO Intercomparison of High Quality Radiosonde Systems
World Meteorological Organization (WMO) ; Oakley T.; Vömel Holger; et al. - WMO, 2011 (WMO/TD-No. 1580)The present report includes a detailed analysis of the QRS intercomparisons, a specific analysis of the SSI group, and draws conclusions and recommendations that are key information for the manufacturers, the NMHS as well as the scientific and climate community. Results show that unprecedented performances have been achieved with QRS while the expected performances to be reached with respect to the GRUAN specifications still require more research. This work is an essential contribution to the WMO Integrated Global Observing Systems (WIGOS) to improve services to society by increasing the data ...
IOM Report, 106. WMO Field Intercomparison of Thermometer Screens/Shields and Humidity Measuring Instruments : Ghardaïa, Algeria, November 2008 – October 2009
The WMO Combined Intercomparison of Temperature Screens/Shields in Conjunction with Humidity Measuring Instruments was carried out in Ghardaïa, Algeria from November 2008 to October 2009, at the kind invitation of the Algerian Meteorological Service and under the leadership of CIMO. This intercomparison allowed testing the performance of the instruments in desert conditions, in a dry, hot and dusty environment. It was planned to carry out a follow-up intercomparison of similar instruments in an arctic environment at a later stage. The main objectives of this intercomparison were to gain knowle ...
