  2. ECMWF re-analysis - Wikipedia

    en.wikipedia.org/wiki/ECMWF_re-analysis

    The ECMWF reanalysis project is a meteorological reanalysis project carried out by the European Centre for Medium-Range Weather Forecasts (ECMWF). The first reanalysis product, ERA-15, generated reanalyses for approximately 15 years, from December 1978 to February 1994. The second product, ERA-40 (originally intended as a 40-year reanalysis ...

    The second product, ERA-40 (originally intended as a 40-year reanalysis) begins in 1957 (the International Geophysical Year) and covers 45 years to 2002. As a precursor to a revised extended reanalysis product to replace ERA-40, ECMWF released ERA-Interim, which covers the period from 1979 to 2019. A new reanalysis product ERA5 has more ...

    The ERA-Interim reanalysis [19] covered the period from 1979 onwards. A reanalysis product (ERA5) [20] with higher spatial resolution (31 km) was released by ECMWF in 2019 as part of the Copernicus Climate Change Service. [21]

    As detailed in Table 4 of Shen et al., these AI-driven models were trained with ERA5 reanalysis data and CMIP6 datasets and evaluated using a variety of metrics such as root mean square errors (RMSE), anomaly correlation coefficients (ACC), Continuous Ranked Probability Score (CRPS), Temporal Anomaly Correlation Coefficient (TCC), Ranked ...

    Analysis by the European Centre for Medium-Range Weather Forecasts (ECMWF) using ERA5 reanalysis data estimated the pressure of the cyclone as 900.7 mbar (26.60 inHg) early on 17 October while a paper published in Geophysical Research Letters in July 2023 got a minimum pressure of 899.91 mbar (26.574 inHg) the same day.

  7. Wind wave model - Wikipedia

    en.wikipedia.org/wiki/Wind_wave_model

    A retrospective analysis, or reanalysis, combines all available observations with a physical model to describe the state of a system over a time period of decades. Wind waves are a part of both the NCEP Reanalysis [ 42 ] and the ERA-40 from the ECMWF. [ 43 ]

    The ECMWF concluded that the cyclone lost its identity on 20 October while the Geophysical Research Letters paper called a dissipation two days later in the southwestern Atlantic Ocean. [ 1 ] [ 2 ] The cyclone lasted roughly for ten days, much longer than typical cyclones in the North Pacific and North Atlantic, although some summer cyclones in ...
