Abstract In an attempt to advance the understanding of the Earth's weather and climate by representing deep convection explicitly, we present a global, four‐month simulation (November 2018 to February 2019) with ECMWF's hydrostatic Integrated Forec

In numerical weather prediction, parameterisations are used to simulate missing physics in the model. These can be due to a lack of scientific understanding or a lack of computing power available to address all the known physical processes. Parameter

Preliminary evaluation of the ECMWF 6th generation ocean and sea-ice reanalysis system (ORAS6)

Autor: Eric de Boisseson, Hao Zuo, Philip Browne, Marcin Chrust, Magdalena Balmaseda, Patricia de Rosnay, Beena Balan Sarojini

Ocean and sea-ice reanalyses are reconstructions of historical ocean and sea-ice states by ingesting observations into simulated model states through data assimilation methods. Reanalysis provides invaluable information for climate monitoring and is

Tropical cyclones are some of the most devastating natural hazards and the “three beasts”—Harvey, Irma, and Maria—during the Atlantic hurricane season 2017 are recent examples. The European Centre for Medium-Range Weather Forecasts (ECMWF) is

Publikováno v: Weller, H, Browne, P, Budd, C & Cullen, M 2016, ' Mesh adaptation on the sphere using optimal transport and the numerical solution of a Monge-Ampère type equation ', Journal of Computational Physics, vol. 308, pp. 102-123 . https://doi.org/10.1016/j.jcp.2015.12.018

An equation of Monge–Ampere type has, for the first time, been solved numerically on the surface of the sphere in order to generate optimally transported (OT) meshes, equidistributed with respect to a monitor function. Optimal transport generates m
