Does Gilbraltar affect the weather in its climatological/meteorological neighbourhood? When I was in Gilbraltar a few years ago, several locals of both Spain and Gibraltar commented on the fact that the peninsula has a weather system distinct from the areas around it, and that the peninsula had an effect on the weather patterns of the surrounding areas (i.e. Spain & north-west Africa). !Gibraltar in twilight (licensed under the "licencia de Creative Commons (“attribution”)", source: < !enter image description here (licensed under the Creative Commons non-commercial attribution, no derivatives source: < From the shape and size of Gibraltar the assertion by the locals seems plausible. Is there a meteorological phenomenon surrounding this mountain that affects the weather of Spain or North-west Africa? Does this big 'ol rock, cast as a Pillar of Hercules, change the weather around it? It's a big rock, no doubt. But is it **_that_** big?

Only a partial answer, that will hopefully be helpful to someone else:

> Mass changes in the nearby Atlantic or winds around Gibraltar can induce sea level changes in the whole basin.

This is not peer-reviewed, and it is about ocean currents, not atmospheric conditions, which I would have though would be closely related but, it says:

> Recent efforts have been devoted to couple ocean and atmospheric models. However, we feel that there is still a lack of clear conclusions about the improvements lead by coupled models in front of forced models.

There is a strong wind weather pattern around Gibraltar called Viento de Levante, which was researched in 1952, but I can't see the actual paper :-(
