Wind at 850 hPa
Descripción:
This map presents the average wind vector at 850 hPa for every modeled gridpoint (ca. 80 km). The average pressure altitude for 850 hPa is at about 1500m a.s.l. (5000 ft). One can read its present altitude from the 'z T 850 hPa' chart. This map is very useful for gliders and hang-gliders if their airfield or starting pad is significantly below the 850 hPa pressure altitude. (wind-converter)
Introduction to seasonal forecasting:
The production of seasonal forecasts, also known as seasonal climate forecasts, has undergone a huge transformation in the last few decades: from a purely academic and research exercise in the early '90s to the current situation where several meteorological forecast services, throughout the world, conduct routine operational seasonal forecasting activities. Such activities are devoted to providing estimates of statistics of weather on monthly and seasonal time scales, which places them somewhere between conventional weather forecasts and climate predictions.
 
In that sense, even though seasonal forecasts share some methods and tools with weather forecasting, they are part of a different paradigm which requires treating them in a different way. Instead of trying to answer to the question "how is the weather going to look like on a particular location in an specific day?", seasonal forecasts will tell us how likely it is that the coming season will be wetter, drier, warmer or colder than 'usual' for that time of year. This kind of long term predictions are feasible due to the behaviour of some of the Earth system components which evolve more slowly than the atmosphere (e.g. the ocean, the cryosphere) and in a predictable fashion, so their influence on the atmosphere can add a noticeable signal.
