In Wind Exposure D, what conditions are primarily present?

• A. Suburban areas
• B. Wooded landscapes
• C. Exposed coastal areas
• D. Rolling terrain

Answer: (C)

Wind Exposure D refers to areas with conditions where there is minimal or no obstruction to wind flow, typically characterized by flat, open terrain. This exposure classification is often seen in settings that allow wind to move across large expanses without interference. Exposed coastal areas experience significant wind because there are few objects to block the airflow. The continuous expanse of water also contributes to higher wind speeds than land, making these areas particularly susceptible to strong wind forces. In contrast, suburban areas, wooded landscapes, and rolling terrain contain features such as trees, buildings, and elevation changes, which can act as buffers and significantly reduce wind velocity. These features provide varying degrees of wind obstruction and help create less intense wind conditions, which is why they do not fit the criteria for Wind Exposure D as accurately as exposed coastal areas do.
