PRECIPITATION AND THE NORTH ATLANTIC OSCILLATION: A STUDY OF CLIMATIC VARIABILITY IN NORTHERN ENGLAND
Variations in precipitation in Yorkshire, UK, are linked to large-scale atmospheric circulation using the North Atlantic Oscillation (NAO) index, objective Lamb weather types, and long-term seasonal and annual precipitation indices at seven sites. Since the 1960s, a significant decrease in summer pr...

Variations in precipitation in Yorkshire, UK, are linked to large-scale atmospheric circulation using the North Atlantic Oscillation (NAO) index, objective Lamb weather types, and long-term seasonal and annual precipitation indices at seven sites. Since the 1960s, a significant decrease in summer precipitation has been observed across the region, with increasing winter precipitation at western locations since 1970. At western sites, precipitation is highly correlated to the NAO, with positive and negative winter-NAO indices producing anomalies from the long-term winter precipitation average of 112 % and 77 % respectively. The recent winter half-year precipitation increase is concentrated in March and related to a large increase in monthly NAO and the increased occurrence of westerly weather types.
