Faced with conditions that sometimes exceeded the limits of the state of the art in forecasting, Météo-France remained on a preparedness status in order to anticipate any changes in the meteorological conditions, to provide the authorities and the population with all necessary warnings, and to contribute in the crisis management. Strong de- mands were made on the staff which fulfi lled its role with rigour and professionalism. More than ever, Météo-France reaffi rmed its image as a permanently committed national meteorological service, combining scientifi c competence and operational expertise for the benefi t of all. The aftermath of some of the meteorological disasters has certainly been very painful. It could nonetheless be said that the considerable progress accomplished by weather forecasting over the last 10 years, as well as the pertinence of the warning systems implemented under the aegis of Météo-France, have contributed to reduce their effects. In the light of these experiences, ways of progress that should quickly bear fruit were placed in evidence to further improve the alert chain, enhance vigilance and the issuance of warnings, and encourage research on small scale phenomena forecasting. Throughout 2010, Météo-France also pursued a major effort to evolve. Its strategy is clear: developing research, maintaining infrastructure excellence, further improving production quality. 4 METEO FRANCE | 2010 ANNUAL REPORT Foreword An internal reorganization, launched in 2009, seeks to simplify current working methods and to free up resources in order to concentrate on challenges for the fu- ture. To this effect, 2010 saw the development of major projects aimed, in particular, at: implementing updated tools for forecasters, promoting advisory forecasting as a users’ service, improving forecasting for the aeronautics as a contribution to the Single European Sky process, rationalising the observation system. Within the scope of these changes, the reorganization of the local offi ces has been initiated to end up in a smaller scope, in which each location will be endowed with real critical size, while still offering the densest meteorological network in Europe. This major change will be one of the Météo-France’s keys for success in the years to come. Thus, although it was confronted with repeated meteorological crises, Météo-France has always remained available for bringing its assistance to all stakeholders, including authorities and citizens, while pursuing its own evolution and preparing for the future. More than ever, Météo-France’s ambition is to remain the reference national meteorolo- gical service, at the service of all citizens.

  • Statement on Weather Analysis and Prediction in Australia
    AMOS Weather Analysis and Prediction Statement Adopted by AMOS Council: 1 August 2017 Australian Meteorological and Oceanographic Society (AMOS) Statement on Weather Analysis and Prediction in Australia This statement provides a summary of some aspects of weather analysis and prediction, with particular focus on Australia. It has been compiled by atmospheric and oceanographic scientists, reviewed by Members of the Australian Meteorological and Oceanographic Society (AMOS), and approved by the AMOS Council as an official AMOS position statement. The statement will expire 5 years from its adoption, or earlier as determined by AMOS Council. Weather forecasts arm people with the advanced warning needed to protect life and property, make important commercial decisions, or to simply make everyday choices such as what to wear each morning. Forecasts are essential for disaster resilience, emergency services, improved public health, defence, energy management, aviation, and of course agriculture, among many other sectors and activities. Weather forecasts are an indispensable part of modern life. In Australia, the Bureau of Meteorology (BoM) has statutory responsibility for making and issuing weather forecasts and warnings. A recent study by London Economics estimated that, "for every dollar spent on delivering Bureau [of Meteorology] services, these services return a benefit of $11.60 to the Australian economy." Some private sector companies complement these taxpayer-funded services by customising forecasts for industry and other users. Research into the underpinning science of weather and its application to weather prediction is conducted in Australian universities, the Commonwealth Scientific and Industrial Research Organization (CSIRO), and of course the BoM. In addition, the universities and the BoM train the nation’s future generation of meteorologists.

    Tropical cyclone ITA made landfall in northeastern Australia on 11 April 2014 Dr. Susanne Haeseler; updated: 17 April 2014 Introduction In Australia, the severe tropical cyclone ITA made landfall near Cape Flattery in northeastern Queensland on 11 April 2014 at about 10 p.m. (12 UTC) (Fig. 1 and 2). Just before, it reached its highest intensity, category 5 on the 5-stage Australian tropical cyclone category system. Cyclones of this strength are very rare in Queensland at the end of the cyclone sea- son in April. Fig. 1: Satellite image on 11 April 2014, 06 UTC. Cyclone ITA is situated off Australia’s northeastern coast. [Source: DWD] 1 Cyclone ITA evolved from a tropical low that was situated southwest of the Solomon Islands in the Coral Sea on 5 April (Fig. 2). It moved westward to Queensland, then southward along the coast, later to the southeast, and back to the Pacific. Hurricane force winds damaged buildings and uprooted trees. Several towns were temporarily cut off as heavy precipitation caused flooding. Fig. 2: Track of tropical cyclone ITA over the Coral Sea and northeastern Australia in April 2014. The Solomon Islands with their capital Honiara are shown in the upper right of the map. The intensity of the tropical cyclone (numbers in the symbols for the cyclone) refers to the 5-stage Australian tropical cyclone category system.
