Without the extraordinary winter 1939/40 (DJF) the shown temperature Europe would be indicated significantly higher then the long term mean. The summer 1940 was regarded very sunny and fairly hot. There might be some logic in the combination of cold winter and hot summer in Northern Europe, but it would complicate the investigation on the influence of naval war on the ‘average weather’ many fold. The summer season, or summer months are therefore not further commended.
