Which term is used to describe the long-term average of weather conditions in a specific area?

The term that describes the long-term average of weather conditions in a specific area is climate. Climate encompasses the typical patterns of temperature, humidity, precipitation, and other atmospheric conditions over extended periods, usually measured in decades. This distinguishes it from weather, which refers to the short-term atmospheric conditions in a specific place at a specific time.

While humidity represents the amount of moisture in the air, it is just one component of weather and climate, rather than a summary of conditions over time. Similarly, a season refers to a division of the year based mainly on changes in weather patterns and daylight, but it does not capture the long-term averages that define climate. Therefore, climate is the correct choice as it best represents the consistent and long-standing weather patterns of a particular region.
