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 ...
Annual time series of the mean temperature at station De Bilt, The Netherlands. Trend in the June maximum temperature from 1950–2009. Anomaly in the number of wet days (precipitation sum greater than 1mm) for June, 2010 with respect to the normal period 1961–1990. Climatology of mean temperature for the normal period 1961–1990.
Microsoft's Aurora system offers global 10-day weather and 5-day air pollution (CO 2, NO, NO 2, SO 2, O 3, and particulates) forecasts with claimed accuracy similar to physics-based models, but at orders-of-magnitude lower cost. Aurora was trained on more than a million hours of data from six weather/climate models. [83] [84]
The answers to that and more can be found below in AccuWeather's comprehensive 2023 Europe summer forecast. Europe is entering the new season, having faced back-to-back summers of brutal, record ...
In the height region between about 85 and 200 km altitude on Earth, the ionospheric plasma is electrically conducting. Atmospheric tidal winds due to differential solar heating or due to gravitational lunar forcing move the ionospheric plasma against the geomagnetic field lines thus generating electric fields and currents just like a dynamo coil moving against magnetic field lines.
With the spring equinox taking place on Monday, March 20, AccuWeather's expert team of international forecasters has released the details of what the upcoming spring season will hold in Europe.
In 1724, George Graham reported that the needle of a magnetic compass was regularly deflected from magnetic north over the course of each day. This effect was eventually attributed to overhead electric currents flowing in the ionosphere and magnetosphere by Balfour Stewart in 1882, and confirmed by Arthur Schuster in 1889 from analysis of magnetic observatory data.
