Final answer:
Climate is the term for the long-term average of daily weather measurements such as precipitation and temperature over decades. Climatology is the study of climate, and is concerned with long-term weather patterns and effects, different from meteorology's focus on the short-term. Option number d is correct.
Step-by-step explanation:
The long-term average from daily measurements of precipitation and temperature is most accurately defined as climate. Climate encompasses not only the average weather conditions over long periods, typically over decades, but also includes the patterns and effects these conditions have on a regional and global scale. It's the general weather patterns that can be expected in a given region over time. For example, a defining feature of climate might be that northern Wisconsin experiences cold, snowy winters and warm summers, allowing for outdoor activities mainly in the summer months. Climatology is the study of climate and is distinct from meteorology, which focuses on short-term weather conditions.
The Köppen-Geiger classification system categorizes various climate types into six basic types (A, B, C, D, E, and H), with H being a subset of E. An understanding of climate is critical, especially as we face global challenges like climate change which refers to long-lasting changes, including increases in global average temperatures and shifts in precipitation patterns.
