Upwelling is the process where deep, cold, nutrient-rich water rises to the surface, replacing the warmer surface water. This has significant effects on the weather and climate of coastal regions.

In the case of upwelling, the cold surface water can lead to different atmospheric conditions, typically resulting in drier conditions. Warmer surface waters generally lead to more evaporation and moisture in the air, which can contribute to rainfall.

Therefore, the correct answer to how upwelling affects the weather of a coastal region would be:

**d. the cold surface water results in drier air and less rainfall.**
