Abstract [en]

The development of the Spanish daily adjusted temperature

series (SDATS) and the Spanish daily adjusted precipitation series

(SDAPS) datasets in the framework of the European Community

(EC)-funded project EMULATE (European and North Atlantic

daily to MULtidecadal climATE variability) enabled the

assessment of long-term annual changes of extreme temperature

and precipitation indices over peninsular Spain for the period

1901–2005. Within this framework, a set of procedures

was developed to generate long-term (1850–2005) daily adjusted

temperature and precipitation series and to use them to

assess changes in climatic extremes. The present report describes

details of the data employed to analyze the behavior of

Spanish climate extremes and discusses the results of investigations

into the annual changes in selected indices that occurred

during the 20th century: exceedances of upper and lower

percentiles of daily maximum (Tmax) and minimum (Tmin)

temperatures, cold-spell duration index (CSDI), warm-spell duration

index (WSDI), daily rainfall (R) exceeding the 95th and 99th

percentiles, simple daily intensity index (SDII), and greatest 1–

and 5-day total precipitation. Upper and lower temperature

percentiles increased during the 20th century over mainland

Spain, but changes in daytime extreme temperatures were

larger than the changes in night-time extreme temperatures.

This pattern, however, shifted slightly in the recent period of

strong warming, with more similar rates of change among daytime

and night-time extreme temperatures. Changes in extreme

precipitation indices were not as evident as those in extreme-

temperature indices, but there was a tendency towards

heavier precipitation.
