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 ...
It comprises a spectral atmospheric model with a terrain-following vertical coordinate system coupled to a 4D-Var data assimilation system.In 1997 the IFS became the first operational forecasting system to use 4D-Var. [2] Both ECMWF and Météo-France use the IFS to make operational weather forecasts, but using a different configuration and resolution (the Météo-France configuration is ...
Data extrapolation, including development or dissipation, can be used to find the likely location of a moving weather system. The intensity of rainfall from a particular cloud or group of clouds can be estimated, giving a very good indication as to whether to expect flooding, the swelling of a river etc. Depending on the area of built-up space, drainage and land-use in general, a forecast ...
Winter storms can bring all sorts of precipitation, from snow and sleet to freezing rain and plain old rain. Here's when each type falls. Does the weather forecast call for snow or ice?
The country has only seen widespread snow coverage on Christmas Day four times since 1960 – in 1981, 1995, 2009 and 2010. The Met Office will continue to provide updates in the coming days in ...
SNOTEL sites make use of meteor burst communications technology. SNOTEL uses meteor burst communications technology to collect and communicate data in near-real-time. VHF radio signals are reflected at a steep angle off the ever-present band of ionized meteors existing from about 50 to 75 miles (80 to 120 km) above the earth.
The castle site has commanding views over the River Trent to the north and the River Mease to the south. The castle complex is large and generally well preserved; it is thought to retain a lot of archaeological remains. The castle was of the motte and bailey type with a central motte (keep) enclosed with three associated bailey enclosures. [2]
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 ...
