This could be considered analogous to a "control" experiment. Another example would be a climatological forecast: "What is the weather going to be like today? The same as it ...
The mathematical model is run four times a day, and produces forecasts for up to 16 days in advance, but with decreased spatial resolution after 10 days. The forecast skill generally decreases with time (as with any numerical weather prediction model) and for longer term forecasts, only the larger scales retain significant accuracy.
Snow occurs when the atmosphere is "cold" all the way from the clouds to down here at the surface. And rain occurs when it's "warm" all the way from the clouds to the surface.
The National Weather Service's Climate Prediction Center is forecasting above-average temperatures across the southern part of the country in its 6- to 10-day temperature outlook, while average ...
The winter storm that's forecast to spread a mix of snow, ice and rain across portions of the central and eastern U.S. this weekend "is just the next in a series of storms," said AccuWeather ...
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 ...
