图2 Example offline emulation of instantaneous short-wave surface tendency (W/m2) from the radiation scheme. Top: using a conventional radiation scheme (ecRAD with the Tripleclouds solver), middle: using a convolutional neural network emulator, bottom: difference between the two. ECMWF还与雷丁大学...
ECMWF的综合预报系统(IFS)的部分内容正在成为开放源码,未来将与成员国协商审查将整个IFS转为开放源码的好处。 目前,在许可方式上对IFS的源代码和ECMWF的其他代码进行了区分。一般来说,非IFS的软件可以在开放源码许可证(Apache-2)下获得,而对IFS的做法则比较严格。IFS的源代码是不公开的,只有ECMWF及其成员国和合作国...
2025年2月25日星期二,新版人工智能预报系统(AIFS)确定性模式将发布并支持运行。此次发布是 ECMWF 历史上的一个重要里程碑,因为 AIFS Single v1 将是第一个全面投入运行的 AIFS 模型。 除了AIFS Single的运行外,v1版本还将取代现有的实验版本v0.2.1。新版本将对确定性 A

Loki is an experimental tool to explore the possible use of source-to-source translation for ECMWF's Integrated Forecasting System (IFS) and associated Fortran software packages.Loki is based on compiler technology (visitor patterns and ASTs) and aims to provide an abstract, language-agnostic ...
系统(AIFS)投入业务运行 2月25日,欧洲中期天气预报中心(ECMWF)正式业务化运行人工智能天气预报系统确定性预报版本(AIFS-Single)。AIFS-Single在热带气旋预报路径误差等多项关键指标上较当前最先进的物理模式性能提升达20%。AIFS-Single通过机器学习(ML)与人工智...
