Location D is most likely to experience frequent summertime storms. Higher relative humidity, such as the 98% in Location D, provides favorable conditions for the formation of storms and precipitation. (option D)
Location D, with an average seasonal relative humidity of 98%, is most likely to experience frequent summertime storms. High humidity levels indicate a significant amount of moisture in the air, a crucial factor for storm development.
The abundant moisture, coupled with atmospheric instability, promotes the formation of thunderstorms. In contrast, lower relative humidity in other locations suggests a comparatively drier atmosphere, which may hinder the formation of storms. Therefore, the elevated humidity in Location D creates an environment conducive to the regular occurrence of summertime storms, making it the most probable candidate among the listed locations.
