Agrometeorology

Climate change and variability and natural disasters in agriculture

WMO is promoting studies of the potential impacts of climate change and variability and natural disasters on agriculture, rangelands, forestry and fisheries. These include studies of mitigation and adaptation strategies. 

Three project areas have been identified where assessment capabilities of impacts are particularly critical: impacts of natural disasters; the contribution of agriculture to the state of climate; and climate forecasts for users. 

Case-studies on specific topics in each area will be carried out in different regions. 

Climate predictions for agriculture 

Adaptation of food production, particularly in areas where climate variability is large, holds the key to improving food security. The range of adaptation options for agriculture, forestry and fisheries is increasing, thanks to technological advances. 

These include increasingly accurate seasonal-to-interannual climate forecasts. Many developing countries, however, have limited access to these technologies and appropriate information on how to implement them.  

WMO is encouraging new approaches to climate modelling, as well as agricultural applications and systems management. Large-scale seasonal-to-interannual forecasts need to be downscaled in a reliable and practical manner for local applications and users need to be trained in their use.

The war against locusts 

Experts from National Meteorological and Hydrological Services and National Locust Control Centres (LCCs) of 11 countries in Africa met recently to discuss roles and responsibilities for more effective coordination and planning in the event of further locust outbreaks during the upcoming rainy season. 

Of particular concern was the dissemination of daily weather data to the LCCs and other international organizations and the potential use of advanced weather forecast model products for locust monitoring and control.

Atmospheric observations

Observations from commercial aircraft 

A three-year 5-million euro infrastructure project entitled “Integration of routine Aircraft measurements into a Global Observing System” (IAGOS) has been launched by the European Commission.  Its aim is to sustain and improve measurements of atmospheric composition from commercial aircraft that began 10 years ago as a series of research projects (MOZAIC). 

The project is a key component of WMO’s strategy for Integrated Global Atmospheric Chemistry Observations (IGACO). 

Chemical observations of the atmosphere are critical for improving the scientific understanding of chemistry-climate interactions, particularly those associated with the roles of clouds and aerosols, for improving weather forecasts and addressing  air-pollution impacts on human health. 

The dataset collected in MOZAIC from more than 20 000 long-haul flights provides a wealth of information on the composition of the upper troposphere/ lower stratosphere and tropospheric profiles for the testing of global and regional chemistry-transport models. 

Building on MOZAIC, IAGOS is designed to build the capability for observations of atmospheric composition, aerosols and cloud particles from commercial aircraft.

Central activities are worldwide aeronautical certification for installation and deployment on long-haul aircraft and real-time data delivery to National Meteorological Services.  

Ground-based in situ and remote sensing observations of atmospheric composition will be merged with routine aircraft  and satellite measurements through the use of “smart interpolators” in a similar fashion to that already done in numerical weather prediction. 

The WMO Global Atmosphere Watch Programme (GAW) is the designated lead in the implementation of the IGACO strategy. GAW will evolve to meet the observational needs and challenges of climate change, ozone depletion, air quality and long range transport of air pollution.

Capacity building

Training in meteorology 

Several participants from southeastern European countries recently received training in radar meteorology and nowcasting. The course also included severe weather forecasting and satellite meteorology. 

WMO co-sponsored a refresher training course on techniques of weather forecasting at the WMO Regional Meteorological Training Centre, Buenos Aires, Argentina. 

At the WMO Regional Meteorological Training Centre, St Petersburg, Russian Federation, trainers in meteorology took a course in computerized methods and technologies, including distance learning. 

Tropical cyclones: forecasts and warnings 

National Meteorological and Hydrological Services play a key role in reducing vulnerability to natural hazards. This is done, not only through forecasts, but also through the dissemination of warnings, community education and collaboration with emergency managers. 

WMO contributes to this process by promoting research and organizing training for tropical cyclone forecasters from all over the world. The aim is to upgrade their capabilities so that they may provide accurate, early and timely warnings about impending tropical cyclone disasters and associated storm surge.

The training covers forecasting techniques, track prediction, intensity forecasting, meteorological satellites and instruments, cyclone genesis and structure, radar, strike probabilities, monitoring and the formulation and issue of warnings. 

Aviation meteorology:  accreditation 

A major focus of recent attention has been the qualifications and training of aeronautical meteorological personnel. 

It is recognized that the range of aeronautical meteorological duties, and the types of personnel who carry out those duties, vary considerably from country to country, as do the mechanisms used to qualify the staff concerned and the means of assessing their competencies. 

WMO will prepare advice concerning the procedures to be followed by National Meteorological Services with respect to the training and qualifications of aeronautical meteorological personnel. 

Education for development 

The United Nations Decade of Education for Sustainable Development has been launched. 

Some of the areas in which WMO, together with its partners, has a key role to play are education as a means of: ensuring a sustainable livelihood; cleaner solutions for industry and the environment; biodiversity; water and sanitation; sustainable energy management; and ocean conservation.

 It will be necessary to re-orient formal education and training through open and distance learning methods. 

Stakeholders will need to develop their own strategies and action plans for the Decade according to national requirements.

Climate

Climate-change indices 

WMO facilitates work on a regional basis to establish climate-change indices. In particular, there is an interest to derive indices from daily data, especially measures of changes in extremes and to fill in blank data areas in the “global” analysis of climate indices. In this way, confidence in local analyses will be increased as they will be placed in a larger, regional context that includes results from neighbouring stations and countries. 

Such work is a good beginning for international cooperation: regional research synergies are enhanced by sharing insights, while analyses between neighbouring countries will be improved, together with the appreciation for data and data archaeology. 

An overarching aim is to make available the data and indices in the analysis available to researchers everywhere.

Regional Climate Centre 

A pilot project in the form of a Regional Climate Centre for Central America will focus on data, services, research and development and capacity building. It will enhance products developed by Members of the region, including seasonal and interannual forecasts, forecast verifications and climate analyses. 

Countries will benefit from more targeted climate forecasts, particularly for El Niño and La Niña events.

Safeguarding the ozone layer and the global climate system 

After 20 years of protecting the ozone layer with a new generation of chemicals, governments are now having to confront the fact that these ozone-friendly substitutes for chlorofluorocarbons (CFCs) also happen to be greenhouse gases that contribute to global warming. 

Although climate change and ozone destruction may appear as being different issues, our use of certain chemicals links them together. 

image

To assess the extent of the problem and the available solutions, the WMO/UNEP Intergovernmental Panel on Climate Change (IPCC), in collaboration with the Technology and Economic Assessment Panel, has produced a special report entitled “Safeguarding the ozone layer and the global climate system: issues related to hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs)”.

 


Climate research

The future for climate research 

Coordinated Observation and Prediction of the Earth System (COPES) is a new strategic framework for climate research for the next 10 years. It addresses new opportunities and challenges in determining the predictability of climate and the effect of human activities on climate. 

COPES will provide a framework for ensuring collaboration among nations and synergy across various climate research activities. It will build new tools to describe and analyse climate variability and change and their combined effects and assess why those effects are occurring. It will also build improved and more comprehensive climate system models and will make climate predictions of greater utility from weeks to centuries and on global to regional scales. 

Finally, it will enable improved climate-change assessments for use in widespread applications in all socio-economic sectors.

Data assimilation 

Humankind needs better predictive capabilities and operational potential to reduce and mitigate natural disasters, and to improve understanding and society’s response to environmental change. Data assimilation is a critical bridge between rapidly progressing information technologies, an increasing volume of observational data and the utilization of data in various domains of the Earth system. 

Through the framework of WMO, all nations, especially developing and least developed countries, may benefit, directly or indirectly, from comprehensive and effective information and products in support of safety of life and property and socio-economic development.

Instruments

METEOREX 

In May, WMO organized in Bucharest, Romania, a technical conference and an exhibition that promoted the interaction of manufacturers and users of meteorological instruments and observing systems. 

image

A total of 254 experts from 71 countries participated in the conference that discussed meteorological and environmental instruments and methods of observation. Some 64 exhibitors participated in the conjointly organized Exhibition of Meteorological Instruments, Related Equipment and Services (METEOREX 2005)—the largest such event in the world.

 

Homogeneous and accurate measurements 

Understanding the Earth’s climatic system, its variability and change, is only possible with homogeneous and accurate data measured worldwide. Intercomparisons of the instruments that measure the data are therefore essential. 

WMO has initiated a new schedule of intercomparisons. The first took place with 19 pairs of rainfall intensity gauges from 18 manufacturers in three laboratories in three countries.   

The next intercomparison was of six radiosonde systems. Divided into two groups, these were launched successively on 2 000 g balloons at four successive launch times. 

The results of the tests are currently being analysed.

Preparing the forecasts 

WMO ensures that atmospheric analyses and weather and climate products are prepared and made available to Member countries in a useful and cost-effective fashion. 

Functions of WMO’s Global Data Processing and Forecasting System (GDPFS) include the preparation of products derived from Numerical Weather Prediction (NWP) systems for nowcasting (0-2 hours ahead) up to long-range forecasts (1 month-2 years ahead). 

These tailored, value-added products are used for a wide range of purposes such as marine and aviation safety and environmental quality monitoring.

Standards for verifying the accuracy and reliability of products are constantly under review for improving forecast product quality. This has, on average, increased by two days over the last 20 years.  

WMO promotes new forecasting techniques by facilitating discussions and organizing training so that developing countries may make the best use of the new techniques and products available. These include forecasts of risk and warnings of severe weather.

Water

Managing water resources 

If surface- and groundwater are not managed wisely, water will become an even more limited and fragile resource than it is today. Integrated water-resources management can help reconcile conflicting uses of water and provide communities with the opportunity to utilize their sometimes scarce water resources optimally. 

WMO and the National Meteorological and Hydrological Services have a primordial role to play in water quantity and quality assessment. Monitoring is the information backbone and knowledge base for integrated water-resources management and for building resilience in society against water-related hazards.

Flood management in Kenya

Integrated Flood Management (IFM) is flood management in the context of Integrated Water Resources Management. 

As one of the leaders in promulgating IFM as a means of attaining sustainable socio-economic development, WMO has initiated a pilot project to assist the Kenyan Ministry of Water and Irrigation develop a Flood Management Strategy for the Lake Victoria basin.
