Air Masses, Fronts, and Various Phenomenons...

Barcelona, Spain while it sets on a coast, the city experiences tropical weather, and what would seem to be a variation of all temperatures close to each changing season.  Summer months usually are extremely warm and humid, which is affected by the cT air masses during those months.  The winter months are not tremendously cold, but during that time the mP air masses set in upon Barcelona's weather conditions.  

While Barcelona is north of the equator, it is still considered to be a Tropical climate, on the Mediterranean Sea.  The region is affected by the ITCZ, during the Summer months, causing thunderstorm activity, with the potential to become tropical storms.

Just this last summer, June 12, 2012, a very rare sandstorm hit the coast of Barcelona.  This amazing storm is referred to as a "atmospheric phenomenon."  This storm was caused by "two separate air masses clashing together."  Most of the people that witnessed it, said the strangest part was that "the skies were still blue."
