Regional differential behaviour of maximum temperatures in the Iberian Peninsula regarding the Summer NAO in the second half of the twentieth century

We found that, for the 1951-1967 period, the negative SNAO contributed to a lowering of the maximum temperatures in the NW and north IP and to a strengthening of the north-south IP maximum temperature gradient. During the 1970s and the start of the 1980s, owing to the much higher values of SNAO, the more negative anomalies in the coldest days shifted towards the east of the IP.
