WWRP, 2018-1. Peer Review Report on Global Precipitation Enhancement Activities
WMO, 2018In order to be most beneficial, this review focuses exclusively on the scientific basis for precipitation enhancement. Hail suppression, fog dispersion or harvesting as well as subjects related to geoengineering were, thus, out of scope for this current assessment. In addition, to provide the most useful information, the report focuses on the two cloud types most seeded in the past: winter orographic cloud systems and convective cloud systems. The review is structured in five thematic chapters
WWRP, 2018-1. 세계 인공증우 활동에 대한 전문가 평가 보고서
KMA, 2018가장 유익한 정보만을 제공하기 위하여 인공증우의 과학적 근거에만 초점을 맞추기로 했기 때문에 지구공학에 관련된 주제뿐만 아니라 우박방지, 안개소산 또는 안개제거도 이번 평가의 범위에서 제외되었다. 또한 가장 유용한 정보를 제공하기 위해, 구름씨뿌리기의 가장 일반적인 대상이었던 겨울철 지형성구름계와 대류성 구름계에 초점을 맞추기로 하였다. 이 평가서는 다섯 가지 주제로 구성되어 있다 .
WWRP, 2016-4. Catalysing Innovation in Weather Science: WWRP Implementation Plan 2016-2023
Weather-related disasters pose a major threat to society, the environment and the economy. As the vulnerability to weather related hazards increases due to climate change, growing population, urbanization and other factors it is imperative to coordinate weather research targeted towards improving forecasts and warnings at international level. The impacts resulting from the underpinning hydro-meteorological events such as heat waves, droughts, floods, landslides, wind storms, landfalling tropical cyclones or severe convective storms are regional or local in nature. Many of these disasters, howe ...
Driving Innovation Together: The World Weather Research Programme
In view of the increasing pressure on water resources, National Hydrological Services (NHSs) worldwide are faced with the challenge to deliver hydrological services of high quality, timeliness and proven credibility, to assist the decision making process of water and natural resources managers. Nowadays, it is commonly expected that these services must be based on information that includes an accurate assessment of its uncertainty. Stream discharge, the basic hydrological variable, is no exception, yet most measurements are still reported as a value without any information on its associated un ...The Young Earth System Scientists (YESS) Community
Bulletin, Vol. 65(1). WMO, 2016Due to human-induced climate change, the planet is undergoing many changes. “We have had years of record Arctic sea ice minimum. We have lost a massive area of northern hemisphere snow cover, probably by more than 1 million square kilometers in the past 15 years,” elaborates David Carlson, Director of the World Climate Research Programme (WCRP). “We are working in a different climate and we do not fully understand the new patterns emerging.” It is in this spirit that the WCRP and the World Weather Research Programme (WWRP) have emphasized the need to form an association where young applied sci ...
WWRP/PPP, 04. WWRP Polar Prediction Project Implementation Plan for the Year of Polar Prediction (YOPP)
The Year of Polar Prediction (YOPP) is planned for mid-2017 to mid-2019, centred on 2018. Its goal is to enable a significant improvement in environmental prediction capabilities for the polar regions and beyond, by coordinating a period of intensive observing, modelling, prediction, verification, user-engagement and education activities. With a focus on time scales from hours to a season, YOPP is a major initiative of the World Meteorological Organization’s World Weather Research Programme (WWRP) and a key component of the Polar Prediction Project (PPP). YOPP is being planned and coordinated ...
Targeted Research for Improved Services: WWRP Implementation Plan 2016-2023, part 2 : (2nd Booklet – Draft 8Apr2016
This is a companion document to the main WWRP Implementation Plan 2016-2023. It provides planned activities by Projects and Working Groups to support the overall WWRP programmatic goals for each of the four Themes and 18 Action Areas listed in that document. It also gives more detail on planned education, training, and capacity building activities to facilitate progress on research, and transfer from research into operations. In square brackets after each bullet-pointed activity are given the projects and working groups involved, including collaborations with key partners outside WWRP.
Catalysing Innovation: WWRP Implementation Plan 2016-2023, part 1 : (1st Booklet – Draft 1Apr2016)
The World Weather Research Programme has been established in 1998 for addressing the growing societal impacts of a range of high-impact weather events, such as landfalling hurricanes and heavy rainfall. It served as an international umbrella beneath which many international and national research programs related to weather prediction can function more effectively. It initiated, endorsed, and facilitated projects that required an especially large critical mass of effort. [...]
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 ...
HIWeather
Despite substantial advances in both forecasting capability and emergency preparedness, recent years have seen a large number of natural disasters that have cost many lives, displaced large numbers of people, and caused widespread damage to property and infrastructure. Many of these disasters result from severe weather interacting with society. At the same time, less severe weather events place a continuing strain on society through more frequent impacts of smaller magnitude. This is especially evident in less developed countries with more fragile economies and infrastructure. In addition, wea ...
Subseasonal to seasonal prediction - Research implementation plan, 22 June 2012
The subseasonal to seasonal timescale provides a unique opportunity to capitalise on the expertise of the weather and climate research communities, and to bring them together to improve predictions on a timescale of particular relevance to the Global Framework for Climate Services (GFCS). A planning group which included representatives from WWRP/THORPEX, WCRP, CBS and CCl drafted the implementation plan, giving high priority to establishing collaboration and co-ordination between operational centres and the research community involved in subseasonal to seasonal prediction, and to sponsorship o ...
WWRP/THORPEX, 18. International Core Steering Committee for THORPEX : final report
The TIGGE-LAM panel was set up by the GIFS-TIGGE working group to coordinate the contribution from Limited Area Model (LAM) Ensemble Prediction Systems (EPS) to TIGGE (the THORPEX Interactive Grand Global Ensemble, Bougeault et al. 2010) and to the proposed GIFS (Global Interactive Forecast System). After a couple of years of activity, the Panel was requested by the WWRP Joint Scientific Committee to develop a Strategic Plan outlining the main scientific and development issues on which TIGGE LAM must concentrate to advance LAM EPS and defining specific activities related to these issues. Furth ...

WWRP, 2011-1. 7th International Workshop on Tropical Cyclones (IWTC-VII)
Since November 1985, WMO has organized a series of quadrennial International Workshops on Tropical Cyclones (IWTCs), the latest of which took place in La Reunion (France) from 10 to 15 November 2010. It is noteworthy that this seventh WMO International Workshop on Tropical Cyclones (IWTC-VII) has been the first held in WMO Regional Association I (Africa). The Workshop primary objectives were to review progress in tropical cyclone research and operational practices since IWTC-VI and to contribute in identifying future research and operational priorities. The six-day meeting set the scene for ex ...
