Question

Which of the following statement is correct about "Equatorial low pressure belt"?

1) It exists between 20 degree north to 20 degree south latitude.

2) This belt represents  the zone of convergence of N-W and S-W Trade winds.

1. Only 1
2. Only 2
3. Both 1 and 2
4. Neither 1 nor 2.

Answer 1

Correct Answer - Option 4 : Neither 1 nor 2.

The correct answer is Neither 1 nor 2.

      Equatorial low pressure belt - 

• The "Equatorial low-pressure belt" is also called as "Doldrums".
• It is called "Doldrums" due to the absence of air movement and generation of low intense pressure.
• This belt exists between 10 degrees north to 10 degrees south latitude.
• This belt is created by high insolation and the convective rise of air.
• This belt represents the zone of convergence of N-E and S-E Trade winds.
• The equator low pressure belt also forms the Inter tropical convergence zone ( ITCZ).
• This is the zone of convergence of trade winds blowing equator ward from the subtropical belt of high pressure in the northern and southern hemisphere.

​

       ITCZ -

• It stands for the Intertropical convergence zone.
• It is known as Doldrums or calms because of it's monotonous and windless weather.
• It encircles the earth near the thermal equator.
