Aircraft normally land at Barcelona's El Prat airport using either of the 25 runways, along a flight path hugging the coast, with a flip to the 07 orientation generally associated with bad weather.
Earlier today, though, my flight landed on a cross runway, 02, which I never knew existed, with a flight path at a rather steeper angle to the coast; there is some light cloud cover but nothing to write home about. What factors drive the change to this mode of operation? I'm interested both in the general criteria and in the specific conditions tonight.
And, more generally, what are the standard resources (or types of resources) that one should use to find out this type of information?
