ECMWF has implemented a significant resolution upgrade and methodology for high-resolution forecasts (HRES) and ensemble forecasts (ENS) beginning January of 2016. HRES is now performed via a transform grid with a nominal grid point spacing of 9 kilometers (0.08 degrees), and is carried out with IFS (Integrated Forecast System) model cycle CY41r2. Improvements in computational efficiency and. Evolution of the IFS The comprehensive Earth system model developed at ECMWF forms the basis for all the data assimilation and forecasting activities. All the main applications required are available through one integrated computer software system (a set of computer programs written in Fortran) called the Integrated Forecasting System or IFS. The IFS undergoes changes regularly in order to improve the forecast. Changes are listed below with their identifier (Cycle 32r1 for instance) or a.

New forecast model cycle brings highest-ever resolution 10 March 2016 ECMWF has launched a new model cycle bringing improved global weather forecasts at record-breaking resolution. In 1997 the IFS became the first operational forecasting system to use 4D-Var . This is true both. This upgrade of ECMWF's Integrated Forecasting System (IFS) implemented on 11 July improves forecast skill in medium-range and monthly forecasts. IFS Cycle 43r3 includes changes in the model and in the assimilation of weather observations. Model changes include a new radiation scheme, improvements in the modelling of convection and a new aerosol climatology. Changes in data assimilation and in the way dropsonde observations are handled have improved the accuracy of the initial conditions. The resolution for the O1280 octahedral grid varies from about 8 km at the equator, increasing to about 10 km at 70 o N and 70 o S before decreasing again towards the poles. The resolution of the N640 original reduced Gaussian grid used for HRES at IFS cycle 41r1 is at about 16 km. Also shown is the regular Gaussian grid at F1280 (black curve)

Climatological surface biases in ECMWF-IFS are relatively insensitive to an increase in atmospheric resolution from ∼ 50 to ∼ 25 km. However, increasing the horizontal resolution of the atmosphere while maintaining the same vertical resolution enhances the magnitude of a cold bias in the lower stratosphere. In coupled configurations, there is a strong sensitivity to an increase in ocean.

In 2019, ECMWF scientists worked on a method to address stratospheric temperature biases without introducing a computationally costly increase in vertical resolution. They showed that, in ECMWF's Integrated Forecasting System (IFS), fifth-order (quintic) vertical interpolation leads to more physical model behaviour, reduced sensitivity to. ECMWF is best known for this global operational forecast model, been officially known as the Integrated Forecast System (IFS) but usually known informally as the ECMWF (European Centre for Medium-Range Weather Forecasts) The IFS is a global model that runs every 12 hours and its output runs out to 10 days (240 hours) in 24 hours intervals. Original IFS resolution is about 50km (0.5º), but. In this study, we used data from the ECMWF-IFS (grid resolution: 0.125°) from 2005 to 2018. The forecast data are issued twice a day at 0000 UTC and 1200 UTC, and the fore-cast lead time is from 24 h to 240 h (10 days). The ground truth used by the correction methods is the ERA5 dataset with the same grid resolution; this dataset has been widely used to replace the previous reanalysis dataset.
horizontal resolution from about 60 km to 25 km [IFS Cycle 30r1 (18)]. In January 2010, the horizontal resolution of HRES was increased to 16 km in the IFS Cycle 36r1 (19). In June 2013, ECMWF increased the number of HRES vertical levels from 91 to 137 for the IFS Cycle 38r2 upgrade (14). The importance of resolution is illustrated in Fig. 1, whic Abstract. Numerical weather forecast systems like the ECMWF IFS (European Centre for Medium-Range Weather Forecasts - Integrated Forecasting System) are known to be affected by a moist bias in the extratropical lowermost stratosphere (LMS) which results in a systematic cold bias there. We use high-spatial-resolution water vapor measurements by the airborne infrared limb-imager GLORIA. One of the main drivers of this project was ECMWF's strategic decision to move towards an ensemble forecast horizontal grid spacing of about 5 km, down from 18 km in 2020. The goal was thus to make it possible for the IFS to be run across a broader range of horizontal resolutions, including convection-permitting resolutions

The sensitivity of the MJO in the IFS to horizontal resolution turns out to be small, at least for the resolutions tested here. One possible explanation is based on the observation that the ratio of large-scale to convective tropical precipitation hardly changes with increasing resolution. This is in contrast, for example, to what has been found for the Community Atmospheric Model Boyle and. . is best known for this global operational forecast model, been officially known as the Integrated Forecast System (IFS) but usually known informally as the (European Centre for Medium-Range Weather Forecasts) The IFS is a global model that runs every 12 hours and its output runs out to 10 days (240 hours) in 24 hours intervals.

The ECMWF Integrated Forecasting System (IFS) has a four-layer representation of soil, where the surface is at 0cm: Layer 1: 0 - 7cm, Layer 2: 7 - 28cm, Layer 3: 28 - 100cm, Layer 4: 100 - 289cm. Soil temperature is set at the middle of each layer, and heat transfer is calculated at the interfaces between them. It is assumed that there is no heat transfer out of the bottom of the lowest layer. ECMWF - The global air-sea-wave-land-ice modeling system of the European Centre for Medium-range Weather Forecasts (ECMWF). The atmospheric component is based on the Integrated Forecast System (IFS) dynamical core. The global domain has a nominal horizontal resolution of ~9 km. ECMWF model forecasts are currently available 4x daily at 24-h. ECMWF is the European Centre for Medium-Range Weather Forecasts. We are both a research institute and a 24/7 operational service, producing global numerical weather predictions and other data for our Member and Co-operating States and the broader community. The Centre has one of the largest supercomputer facilities and meteorological data archives in the worl Today ECMWF uses a 16 km global grid for its operational deterministic model, and plans to scale up to a 10 km grid in 2014-15, followed by a 5 km grid in 2023-24, and a 2.5 km grid in 2031-32. These future resolution increases will require IFS to run efficiently on about 4 million cores in the 2030's on an exascale sized system that is expected to be both available and affordable by then The ECMWF NR (ECO1280) uses the TCo1279L137 configuration of the ECMWF Integrated Forecast System (IFS) model. This model version has 9-km (average) resolution in gridpoint space, T1279 spectral truncation, and 137 vertical layers. For physical processes (convection, radiation, etc.) the ECO1280 uses an octahedral reduced Gaussian grid (O1280). The vertical model structure is a hybrid sigma.
. For occasions with fog HARMONIE-AROME is the most accurate, possibly due to finer resolution, while ECMWF-IFS has a better aerosol representation and is the most accurate at higher visibility ranges. For the cloud base height WRF and ECMWF-IFS provide the best forecasts, despite their low resolutions, and superior parameterizations may therefor be the reason for their better forecasts. A. The IFS is coupled hourly to the 75 level version of the NEMO v3.4 ocean model and the LIM2 sea-ice model, both of which use the ORCA025 tripolar grid. Coupling follows the implementation used in ECMWF operational forecasts. During the first 10 days of the forecast, SSTs seen by the atmosphere are derived by adding ocean model SST tendencies to observed values at initialization time that. ECMWF Jetzt ausgewählt.
