New monthly indices for the East Atlantic and the Scandinavian patterns beyond the 20th century
Climate variability in the North Atlantic sector is commonly ascribed to the North Atlantic Oscillation. However, recent studies have shown that taking into account the second and third mode of variability (namely the East Atlantic ¿ EA ¿ and the Scandinavian ¿ SCA ¿ patterns) greatly improves our u...

Climate variability in the North Atlantic sector is commonly ascribed to the North Atlantic Oscillation.

The most commonly used EA and SCA indices span the period from 1950 to present, which is too short, for example, to calibrate palaeoclimate records or assess their variability over multi-decadal scales.
