Suppose the outflow of air around a surface high-pressure area is greater than the convergence of air aloft. Which of the following conditions would be observed?
A)decrease in the central pressure
B)increase in pressure in the centre of the high
C)movement of the high toward the northeast
D)strengthening in the high

Question

Quizplus · Accepted Answer

When the outflow of air around a surface high-pressure area is greater than the convergence of air aloft, it leads to a decrease in the central pressure. This is because the excess outflow without sufficient replacement from above reduces the mass of air in the high-pressure system, thereby lowering its pressure.
