What is the tropical convergence zone? Is Vietnam affected by the tropical convergence zone?

The tropical convergence zone is a band of bad weather, formed by the convergence of the trade winds of the two hemispheres, of the trade winds of one hemisphere with the trade winds of the other hemisphere crossing the equator and changing direction, and the trade winds of each hemisphere with the expanding equatorial westerly wind zone.

Vietnam is affected by the tropical convergence zone with one side being the southwest wind and the other side being the east or southeast trade winds blowing in from the East Sea-Pacific Ocean. The convergence zone affects our country from about June to September .

Effects of tropical convergence zones: Areas where convergence zones are active often cause widespread heavy rain and thunderstorms.

The tropical convergence zone usually operates in the intra-mesotropical region.

The tropical convergence zone moves north or south depending on the apparent motion of the Sun.

In winter, when the northern hemisphere trade winds are strong, they cross the equator to the southern hemisphere and change to a northwesterly direction, converging with the southern hemisphere trade winds. Therefore, the convergence zone in winter is usually located south of the equator.

In summer, the tropical convergence zone often moves from south of the equator to north of the equator due to the strong southern hemisphere trade winds that rise north of the equator and converge with the northern hemisphere trade winds.

In autumn and spring, when the two hemispheres' trade winds operate stably together, the tropical convergence zone tends to be located in the equatorial region.
