ECMWF is also about to start experimental running of a monthly forecast system. Sensible interpretation and use of numerical seasonal and monthly forecasts is not easy, and the present status of key issues will be discussed.Tim StockdaleProceedings of a workshop held at ECMWF Eighth Workshop on ...
The investigation of the height variations of the westerly in the mid-latitudes of the Northern Hemisphere is crucial for monitoring changes in the intricate atmospheric system. This study examined the hypothesis of changes in the thickness of the westerly domain by analyzing the height of the 500...
简介:Google Earth Engine ——ERA5-Land Monthly Averaged by Hour of Day - ECMWF Climate Reanalysis数据集 ERA5-Land is a reanalysis dataset providing a consistent view of the evolution of land variables over several decades at an enhanced resolution compared to ERA5. ERA5-Land has been produced...
Monthly Weather Review (MWR) (ISSN: 0027-0644; eISSN: 1520-0493) publishes research relevant to the analysis and prediction of observed atmospheric circulations and physics, including technique development, data assimilation, model validation, and releva
ERA5-Land是通过重放ECMWF ERA5气候再分析的陆地部分产生的。再分析将模型数据与来自世界各地的观测数据结合起来,利用物理学定律形成一个全球完整的、一致的数据集。再分析产生的数据可以追溯到几十年前,提供对过去气候的准确描述。这个数据集包括CDS上的所有50个变量。
To investigate the effectiveness of the proposed Bernoulli-Gamma-Gaussian model, numerical experiments are devised to calibrate S2S precipitation forecasts generated by the ECMWF (Vitart et al., 2017) Integrated Forecasting System (IFS). Show abstract Spring precipitation forecasting with exhaustive ...
The ECMWF forecast system tends to yield higher prediction skill than the other two systems, in terms of both correlation and mean squared skill score. However, all three systems are found to exhibit large conditional biases in the tropics, highlighted using the mean squared skill score. The ...
The first-guess field used a simple snow accumulation, aging and melt model driven by 6-hourly values of air temperature and precipita- tion from the European Centre for Medium-range Weather Forecasting (ECMWF) ERA-15 Reanalysis with exten- sions from the Tropical Ocean Global Atmosphere (TOGA...
(mm) is extracted from weather and climate data provided at 2.5 min or(∼21km2)spatial resolution (worldclim.org/data/monthlywth.html and worldclim21.html). The average monthly relative humidity is derived from ECMWF Medium-Range Weather Forecasts from ERA-Interim global atmospheric reanalysis. ...
The PWV was calculated through Zenith Total Delay (ZTD) from the Precise Point Positioning (PPP) technique and metrological data from the European Centre for Medium-Range Weather Forecasts (ECMWF). The relationship between PWV derived from GPS and the precipitation from the Tropical Rainfall ...
