Surface air temperature changes March-May 1900-1935 estimated as the difference between the simple 11yr means for the periods 1895-1905 and 1930-1940. Longitudes and latitudes are indicated along the axis of the diagram.
The period 1900-1935 is generally in Europe recognised as a period

in these regions. In contrast, most regions around the western and central Mediterranean experienced a cooler spring
