Surface air temperature changes September-November 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.
Autumn (September-November)
The period 1900-1935 is generally in Europe recognised as a period
of rapid warming after the end of the Little Ice Age. The autumn conditions
appear to mirror the summer (JJA) conditions: warmer conditions over most over
Europe, with the exception of the Iberian Peninsula and parts of central Europe.
Also an area north of the Black Sea show a cooling tendency during this period.
