Abstract
The temporal behavior of annual frequency of heat waves, produced between 1961 and 2010, is established. From the daily data of temperature, the maximum and the minimum temperature anomalies (ATMAD and ATMID) for the studied zone are obtained. The values of the thresholds of these anomalies, determined by the 90 percentile of the corresponding series are calculated. The existence of heat wave is established when there are two or more consecutive days in which ATMAD and ATMID exceed, at the same time, the values of the corresponding thresholds. The heat waves that have affected the Spanish Central Plateau during the study period are identified, and its annual and monthly frequencies are established. The results indicate that the months of highest number of waves of heat between 1961and 2010 are May (25 waves) and June (23 waves). Analysis of trend of the series of annual frequencies obtained indicates that there is an increasing trend of heat waves to a greater than 99% confidence level. The linear model establishes that there has been an increase in the frequency of heat waves in the Spanish Central Plateau in the order of 0.6 waves every 10 years.
