Q: What is the main effect of downdrafts on temperatures in the areas they pass through?

Arab Weather - Descending winds lead to an increase in temperatures in the areas they pass through, due to their dry and warm nature. When the winds descend from the upper layers of the atmosphere to the surface, they are compressed and heated due to the increasing air pressure as they approach the ground. This leads to heating the air, which causes temperatures to rise significantly in those areas.
