中4關於monsoon的問題

In fact, in summer, the monsoon blows from Australia (Southern Hemisphere) to Asia (Northern).

The formation of the monsoon is due to great pressure difference between Australia and Asia. In Australia, it is winter, so the air molecules cool down, condense and become denser. So, that will result in high pressure. In Asia, it is summer. So the air molecules are heated, expand and become less dense. So that will result in low pressure.

Therefore, monsoon blows from Australia to Asia. You are partly correct. The monsoon initiate from the Australia continent is dry. However, there is Pacific Ocean between Australia and Asia. So, as the monsoon blows to Asia, it brings along the moisture to the Asia continent. So the monsoon is wet. This favours the formation of precipitation. And bring along much rainfall in summer.
