The aim of the HIRLAM programme is to develop and maintain a numerical short-range weather forecasting system for operational use by the participating institutes. The cooperation, started in September 1985, comprises a series of 3-year projects between 1985 and 2005, and 5-year programmes HIRLAM-A (2006–2010) and HIRLAM-B (2011–2015).
ECMWF aims to provide accurate medium-range global weather forecasts out to 15 days and seasonal forecasts out to 12 months. [11] Its products are provided to the national weather services of its member states and co-operating states as a complement to their national short-range and climatological activities, and those national states use ECMWF's products for their own national duties, in ...
Along with the NWS's Global Forecast System (GFS), which runs out to 16 days, the ECMWF's Integrated Forecast System (IFS), which runs out 10 days, the US Naval Research Laboratory Navy Global Environmental Model (NAVGEM), which runs out eight days, the UK Met Office's Unified Model, which runs out to seven days, and Deutscher Wetterdienst's ...
Yr.no generates weather forecasts for millions of places around the world. Its 3-day forecast uses two different weather models with a 2.5 km resolution in Scandinavia and the Norwegian islands, and for other places, the ECMWF's IFS model in high-resolution configuration (HRES), with a 9 km resolution.
The highest resolution "HRES" configuration is run every 6 hours (00Z and 12Z out to 10 days, 06Z/18Z out to 90 hours) with a horizontal resolution of 9 km using 137 layers in the vertical. [3] The 51-member ensemble system "ENS" is also run every twelve hours out to 15 days and every 06Z/18Z out to 6 days with a horizontal resolution of 18 km ...
The NetCDF-Java Common Data Model is a Java library that can read GRIB 1 and GRIB 2 files. zyGrib a graphical software for Linux, Mac OS X and Windows (GPL3, Qt) to download and display GRIB 1 and GRIB 2 (since v8.0) files. XyGrib started as a fork of zyGirb 8.0.1. It is a multiplatform software also.
The Weather Research and Forecasting (WRF) Model [1] (/ ˈ w ɔːr f /) is a numerical weather prediction (NWP) system designed to serve both atmospheric research and operational forecasting needs, developed in the United States. NWP refers to the simulation and prediction of the atmosphere with a computer model, and WRF is a set of software ...
The MM5 is a limited-area, terrain-following sigma coordinate model that is used to replicate or forecast mesoscale and regional scale atmospheric circulation. [1] It has been updated many times since the 1970s to fix bugs, adapt to new technologies, and work on different types of computers and software.
