Storylines and Climate Services [...] day – and it is not the same each day! Consider a summer day somewhere in Europe with an Atlantic ocean breeze, and compare it to a day influenced by winds blowing from the continent. The latter will tend [...] more strongly affected by climate change, simply because the continents warm more strongly than the oceans. Can we be more specific? Yes! By using a climate model in a special way, where the winds are forced
