Mediterranean climate is associated with hot-dry summer and mild-wet winter.
This is classified as Cs here C denote the average zonal temperature which is range is between 0°C to 18°C and s denote the precipitation pattern
In summer the subtropical high pressure anticyclonic cell brings dry sinking air on the top of marine air with varying humidity which leads to clear skies, high temperature and no rainfall.
In winter days the subtropical high anticyclonic cell moves toward equator and those high pressure areas are replaced by frontal cyclones and associated periodic storms bringing rain in lower elevations along with snow in higher ones.
