Step 1
The data shows significant variation both within Saudi Arabia but also across the wet and dry season in the same places.
Answer
Analysis of Figures 3a and 3b indicates that the wet season runs from November to April, while the dry season occurs from June to September. In the wet season, rainfall varies significantly, with some areas receiving up to 250 mm, such as the coastal region, while others, like Rub' al Khali, show minimal rainfall.
In Figure 3a, it is evident that regions along the western coast of Saudi Arabia typically receive more rainfall, generally ranging from 60-150 mm, while the interior areas develop a stark contrast.
In the dry season depicted in Figure 3b, the rainfall is markedly less, with most areas receiving between 0-20 mm, illustrating the arid conditions in many parts of the country. Notably, the northeastern regions experience slightly more rainfall than the rest, reaching up to 40 mm.
Moreover, comparison of both figures shows that some locations in the northwest that receive significant rainfall in the wet months experience a stark decrease in precipitation during the dry months, with differences of up to 140 mm across seasons.
