Ombrothermic diagram according to the Gaussen aridity index.The chart illustrates the monthly climatic trend, comparing the mean temperatures (Tmed, red line, °C, left-hand axis) with the total precipitation (Precip, light blue bars, mm, right-hand axis).The diagram is constructed following Gaussen's rule, wherein the precipitation scale (mm) is double that of the temperature scale (°C), according to the P = 2T relationship. This configuration is essential for visually identifying the period of aridity.The arid period occurs when the temperature curve is positioned above the precipitation bars (P < 2T). In this specific case, the months of July and August, indicated by hatching, represent the year's arid period.
