ECMWF aims to provide accurate medium-range global weather forecasts out to 15 days and seasonal forecasts out to 12 months. [11] Its products are provided to the national weather services of its member states and co-operating states as a complement to their national short-range and climatological activities, and those national states use ECMWF's products for their own national duties, in ...
The Meteorological Office, abbreviated as the Met Office, [2] is the United Kingdom's national weather and climate service. It is an executive agency and trading fund of the Department for Science, Innovation and Technology and is led by CEO [3] Penelope Endersby, who took on the role as Chief Executive in December 2018 and is the first woman to do so.

The ENIAC main control panel at the Moore School of Electrical Engineering operated by Betty Jennings and Frances Bilas. The history of numerical weather prediction began in the 1920s through the efforts of Lewis Fry Richardson, who used procedures originally developed by Vilhelm Bjerknes [1] to produce by hand a six-hour forecast for the state of the atmosphere over two points in central ...
This can be valid when the weather achieves a steady state, such as during the summer season in the tropics. This method strongly depends upon the presence of a stagnant weather pattern. Therefore, when in a fluctuating pattern, it becomes inaccurate. It can be useful in both short- and long-range forecast|long range forecasts. [65]
Prognostic chart. A prognostic chart is a map displaying the likely weather forecast for a future time. Such charts generated by atmospheric models as output from numerical weather prediction and contain a variety of information such as temperature, wind, precipitation and weather fronts. They can also indicate derived atmospheric fields such ...
Climate Forecast System (NCEP) The Climate Forecast System or coupled forecast system (CFS) is a medium to long range numerical weather prediction and a climate model run by the National Centers for Environmental Prediction (NCEP) to bridge weather and climate timescales. [1] Version 2 became operational as CFSv2 in 2011.
A second strike took place on 14 March 2019 in Amsterdam. With 5.000 to 6.000 students striking. [59] A third climate strike took place on 24 May 2019 with 1.500 students striking in Utrecht. [60] On 20 September 2019 2.500 students protested in Maastricht. [61] On 27 September 2019 the biggest protest took place with 35.000 people attending in ...
Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. [ 1 ] On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, [ 2 ][ 3 ] just below the stratosphere. Weather refers to day-to-day temperature ...
