Hottest November 5 on record in the world; parts of Europe experienced record or near record autumn heat – YubaNet

December 7, 2021 – The Copernicus Climate Change Service (C3S), implemented by the European Center for Medium-Range Weather Forecasts on behalf of the European Commission with EU funding, regularly publishes monthly climate bulletins reporting on observed changes in the weather. surface air temperature, sea ​​ice cover and hydrological variables. All reported results are based on computer-generated analysis using billions of measurements from satellites, ships, airplanes and weather stations around the world.

Surface air temperature in November and boreal fall (September-November) 2021:

  • Globally, November 2021 is estimated to be the fifth hottest November on record
  • The global average temperature of November 2021 was almost 0.2 ° C cooler than the record of November 2020, but very close to the temperatures of the other warmer November: 2015, 2016 and 2019
  • The temperature over Europe was broadly close to its 1991-2020 average, for the fall as a whole as well as in November, but Ireland, Great Britain and southern Scandinavia experienced record autumn heat or almost record
  • Regions with well above average temperatures for November and the season include most of North America, particularly northeastern Canada, much of Siberia, and most of the ‘Africa and the Middle East
  • The month and season were cooler than average in far eastern Russia and Alaska, as well as much of Central Asia and Australia

The maps and cited data values ​​for temperature come from the ERA5 dataset of the Copernicus Climate Change Service of the ECMWF. Temperature averages over the European region are only for lands with the following longitude / latitude limits: 25W-40E, 34N-72N.

The C3S followed the recommendation of the World Meteorological Organization (WMO) to use the most recent 30-year period to calculate climatological averages and switched to the 1991-2020 reference period for its C3S climate bulletins covering January 2021 and from. Figures and charts for the new and previous period (1981-2010) are provided for transparency purposes.

Remarks:

Copernicus is a component of the European Union’s space program, funded by the EU, and is its flagship Earth observation program, which operates through six thematic services: Atmosphere, Marine, Earth, Climate Change, Security and Emergency. It provides operational data and freely accessible services providing users with reliable and up-to-date information relating to our planet and its environment. The program is coordinated and managed by the European Commission and implemented in partnership with the Member States, the European Space Agency (ESA), the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), the European Forecast Center Medium-Term Meteorological (ECMWF), EU agencies and Mercator Ocean, among others.

The ECMWF operates two services of the EU’s Copernicus Earth Observation Program: the Copernicus Atmosphere Monitoring Service (CAMS) and the Copernicus Climate Change Service (C3S). They also contribute to the Copernicus Emergency Management Service (CEMS), which is implemented by the EU’s Joint Research Council (JRC). The European Center for Medium-Range Weather Forecasts (ECMWF) is an independent intergovernmental organization supported by 34 states. It is both a research institute and a 24/7 operational service, producing and disseminating digital weather forecasts to its member states. These data are fully available for the national meteorological services of the Member States. The ECMWF supercomputer facility (and associated data archive) is one of the largest of its kind in Europe and member states can use 25% of its capacity for their own purposes.

The ECMWF has extended its presence across its member states for certain activities. In addition to a headquarters in the UK and a data center in Italy, new offices focused on activities carried out in partnership with the EU, such as Copernicus, are located in Bonn, Germany from summer 2021.
