Climogramma di Walter & Lieth

Description

Walter and Lieth aridity index climograph. The graph compares the annual trend of mean temperature (red line, left y-axis in °C) and precipitation (blue line, right y-axis in mm). The hatched area between June and August highlights the arid season, defined by the condition where precipitation is less than twice the temperature ($P < 2T$). This profile, with hot, dry summers and mild, rainy winters, is typical of a Mediterranean climate.
