Final answer:
Cs (Mediterranean) climates have dry summers and wet winters due to the influence of ocean and sea. High-pressure systems during the summer prevent precipitation, while low-pressure systems during the winter bring moisture and precipitation.
Step-by-step explanation:
Climates classified as Cs, which refer to Mediterranean climates, have dry summers and wet winters mainly due to the ocean and sea influence on these regions. Cs climates are characterized by moderate temperatures, with warm summers and mild winters. During the summer, high-pressure systems over the ocean cause the air to sink, inhibiting cloud formation and precipitation. In contrast, during the winter, low-pressure systems move in from the ocean, bringing moisture and precipitation to the region.
