Final answer:
The Arabian Peninsula predominantly has arid type B climates with high temperatures and low rainfall, with variations including the type H highland climate and a more moderate type C climate in coastal regions.
Step-by-step explanation:
The Arabian Peninsula features a variety of climates, but the dry or arid type B climates are the most dominant throughout the region. These environments are characterized by extremely high temperatures, especially in the summer when it can exceed 120 °F, and very little precipitation, with some areas like Saudi Arabia averaging around four inches of rainfall per year. The central part of the Peninsula is known for the Rub' al-Khali or the "Empty Quarter," which is one of the largest sand deserts in the world. However, there are variations, such as the type H highland climate in the southwest, specifically in Yemen, where the elevation results in somewhat cooler temperatures and more rainfall than the surrounding desert regions. Additionally, the type C climate can be found in the coastal areas, offering more moderate conditions with hot, dry summers and cool, wet winters.
