  • Weather forecasting


    Forecast of surface pressures five days into the future for the North Pacific, North America, and the North Atlantic OceanWeather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere at a given place and using meteorology to project how the atmosphere will change. Once calculated by hand based mainly upon changes in barometric pressure, current weather conditions, and sky condition or cloud cover, weather forecasting now relies on computer-based models that take many atmospheric factors into account. Human input is still required to pick the best possible forecast model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and knowledge of model biases.

  • European Centre for Medium-Range Weather Forecasts


    The European Centre for Medium-Range Weather Forecasts (ECMWF) is an independent intergovernmental organisation supported by most of the nations of Europe and is based at Shinfield Park, Reading, United Kingdom. It operates one of the largest supercomputer complexes in Europe and the world's largest archive of numerical weather prediction data. ECMWF was established in 1975, in recognition of the need to pool the scientific and technical resources of Europe's meteorological services and institutions for the production of weather forecasts for medium-range timescales (up to approximately two weeks) and of the economic and social benefits expected from it. It comprises 22 European countries: the eighteen founding states of 1975: Austria, Belgium, Croatia, Denmark, Finland, France, Germany, Greece, Republic of Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, Turkey, United Kingdom. four states that joined since 2010: Iceland (April 2011), Slovenia (December 2012), Serbia (January 2015) and Croatia (January 2016).

  • Climate of Ireland


    A typical North Atlantic low-pressure area moving across Ireland Köppen climate types in Ireland The climate of Ireland is mild, moist and changeable with abundant rainfall and a lack of temperature extremes. Ireland's climate is defined as a temperate oceanic climate, or Cfb on the Köppen climate classification system, a classification it shares with most of northwest Europe. The country receives generally cool summers and mild winters. It is considerably warmer than other areas on its latitude, because it lies in the northeastern Atlantic Ocean, and as a result is warmed by the North Atlantic Current all year. As a small island downwind of a large ocean, the climate of Ireland is profoundly impacted by that ocean. The Atlantic overturning circulation, which includes ocean currents such as the North Atlantic Current, moves heat northwards, which is then carried by the prevailing winds towards Ireland. The prevailing wind blows from the southwest, breaking on the high mountains of the west coast.
