Hi,

enclosing the link to a paper dealing with continentality based on precipitation regimes in Europe.

thank you all for your replies. if possible, I would ask a paper in which the continentality indexes based on air temperature and latitude has been described and their values has been analyzed....

Hi again,

air temperature based continetality in Europe by the same author.
