摘要: Trends in the number of extreme hot days (days with SST anomalies higher than 95% percentile) were analyzed along Canary upwelling ecosystem (CUE) over period 1982–2012 by means data retrieved from NOAA OI1/4 Degree. The analysis will focus on Atlantic Iberian sector and Moroccan subregion where is seasonal (spring summer) permanent, respectively. both near coast at adjacent ocean increase higher. Changes are clear annual scale an increment 9.8 ± 0.3 (9.7 ± 0.1) dec−1 11.6 ± 0.2 (13.5 ± 0.1) (Moroccan subregion). differences between shore trends especially patent for months under intense conditions. During that season highest excess coastal locations (Δn(# dec−1)) occur those regions high. Actually, Δn have shown to be significantly correlated areas, R = 0.88 (p < 0.01) R = 0.67 subregion.
