If air over the warmer area rises.....?

Question

creating a lower atmospheric pressure, how would surrounding air move?

Answer 1

Warmer air does not rise at a uniform rate. Depending upon the "ground level" over water, open fields, trees, buildings, pavement and concrete, the air not only rises at different rates, but also in volume. Atmospheric pressure is not constant in many surrounding areas. 1 millibar of pressure difference will also cause air movement, although it may not be very noticeable.

Answer 2

AIR ALWAYS FLOWS FROM HIGH PRESSURE TO LOW PRESSURE SO WE CAN ASSUME AS THE WARMER AIR RISES MORE WILL FLOW IN UNDER IT TO TAKE ITS PLACE. NATURE ABHORS A VACUUM.
