You mention the intersection of a vertical divisor with a divisor. Now, take a horizontal divisor D on X. Then D surjects onto S. So D lies above all the primes of S. But now add formally the infinite points s on S (the embeddings of K into C). Then D should also lie above these points in a sense. When you intersect a horizontal divisor with D you expect to have some contribution at infinity. See Chapter 1.1 and 1.2 of de Jong's thesis math.leidenuniv.nl/~rdejong | |
