Natural ventilation relies on the movement of air through and around a structure, primarily driven by wind currents. However, atmospheric conditions play a significant role in this process. Atmospheric pressure, for instance, can influence how air flows both into and out of a building. High pressure often correlates with stable air conditions, which may limit air movement, while low pressure can create more dynamic airflow, enhancing natural ventilation.

Beyond just wind, factors such as changes in temperature can create pressure differences that drive air circulation. Therefore, while atmospheric conditions encompass a broad range of elements that affect air movement, they fundamentally interact with and influence natural ventilation effectiveness in various environments. This aspect highlights the importance of understanding local weather patterns and atmospheric behaviors when assessing how well a structure ventilates naturally, as they can significantly alter the conditions under which air exchanges occur.
