How are the climates of northern and southern europe alike and different?

There are differences between the different parts of Europe, but not everybody within an area will fit the mold. On top of that there have been people moving around within Europe for as long as Europe has had people living there.

People often say that Mediterranean Europeans are more passionate than people from the north. This might be true in some cases but I think it is also upbringing. If living in Western Europe, kids are told to not show what they feel all the time, not trow tempers, not to shout when upset. In the south this behavior is more accepted and not seen as bad in the same rate.

There is no line that divides north and south, or even north from central and central from south.
Vienna as all Austria is considered central, like Switzerland and the southern parts of Germany, Czech Republic, Slovakia and Hungary, which are neighbours and have always had influence on Vienna as well as being influenced by it.

When we talk about Northern Europe it is more Norway, Sweden, Finland, maybe also Denmark and Northern Germany, as well as the Baltic republics.
West is Ireland, UK, Netherlands, maybe again a part of Germany and France.
