Figure 5.
Two time-series line graphs illustrating performance ratio anomalies, P R anomalies, plotted against date and hour in U T C. Graph a corresponds to the period from late July to early August 2024, while graph b corresponds to late June to early July 2025. In both graphs, the line represents temporal variations in P R anomalies, with the horizontal zero line indicating baseline performance. The shaded region marks the heatwave duration. Diamond symbols identify the trough points associated with the largest negative anomalies, and square symbols indicate recovery points where the P R returns to approximately ninety percent of its normal level. The graphs highlight strong performance fluctuations during heatwave conditions, followed by stabilization and recovery after the heatwave period ends.Performance ratio anomalies during and post-heatwave for Ariza. (a) 1S; (b) 2S
