"Spring is in the Air" [Editorial]

That was what we all were thinking in January 2014 in Belgium. Instead of having cold and cleaning up some snow, we were wearing short-sleeves and light jackets. Nature got confused. Very unusual... For the first time, no white Christmas 2013 in G??vle, Sweden. But, many states in the U.S. were freezing. Very exceptional... 40 degrees Celsius in Monterey, California, in April 2014. The past year the weather has been behaving like a real out-lyer, far outside the uncertainty bounds... Although the weather can be very unpredictable and uncontrollable, each day weather forecasters are trying hard to be able to predict the weather and warn us for the unpredictable forces of nature. Weather forecasting is one of the most difficult sciences! One has to develop powerful models dealing with a huge amount of variables and taking into account a big uncertainty.
