Air will flow from the higher pressure area to the lower pressure area.
Explanation:
* Pressure Differences: The difference in barometer readings indicates a pressure gradient. The barometer with the higher reading is in an area of higher atmospheric pressure.
* Air Movement: Air naturally flows from areas of high pressure to areas of low pressure. This is because air molecules are constantly moving, and when they're more densely packed (higher pressure), they collide more frequently and push outward, seeking to equalize the pressure.
* Wind: The movement of air from high to low pressure creates wind. In this case, the wind would flow from the area of the higher-reading barometer towards the area of the lower-reading barometer.
Important Note:
* Local Conditions: The actual wind flow and its strength would depend on a variety of local factors, such as the terrain, temperature differences, and other weather patterns. A one-kilometer distance might not be enough to create a strong wind, but the pressure difference would still cause some air movement.
