The significance of ITCZ for India is its contribution to the Indian monsoon. In July when ITCZ is located in the north, it creates the Monsoon Trough. … In winter, the ITCZ moves southward, and so the reversal of winds, from northeast to south and southwest, takes place thus leading to the Northeast monsoon.
What is the role of ITCZ in monsoon?
The area near the equator with low pressure and converging, rising winds is called the Intertropical Convergence Zone (ITCZ). Water vapor condenses as air rises and cools in the ITCZ, forming clouds and falling as rain. … This is where monsoon rainfall occurs.
What is ITCZ belt How does it help Indian monsoon in causing rainfall?
You must know that winds move from high pressure to low pressure, therefore when the winds meet an area of low pressureis created on the landmass which in turn brings in winds with moisture causing rainfall. This is how the ITCZ affects the Indian monsoon.
How ITCZ influence the climate of India?
These winds collect moisture as they travel over the warm Indian Ocean. In the month of July, the ITCZ shifts to 20°-25° N latitude and is located in the Indo-Gangetic Plain and the south-west monsoons blow from the Arabian Sea and the Bay of Bengal. The ITCZ in this position is often called the Monsoon Trough.
How is ITCZ responsible in bringing rainfall to our country during summer?
When the ITCZ is to the south of the equator, the north-east winds prevail over Nigeria, producing the dry-season conditions. When the ITCZ moves into the Northern Hemisphere, the south westerly wind prevails as far inland to bring rain fall during the wet season.
What is the role of ITCZ?
The ITCZ (Intertropical Convergence Zone) play important role in the global circulation system and also known as the Equatorial Convergence Zone or Intertropical Front. It is a basically low pressure belt encircling Earth near the Equator. It is a zone of convergence where the trade winds meet.
What are the factors that affect Indian monsoon?
Factors influencing the onset of SW monsoons:
- Intense low-pressure formation over the Tibetan Plateau.
- The permanent high-pressure cell in the South of the Indian Ocean.
- Subtropical jet stream.
- African Easterly jet (Tropical easterly jet)
- Inter-Tropical Convergence Zone (ITCZ)
What is the full form of ITCZ?
The Intertropical Convergence Zone, or ITCZ, is the region that circles the Earth, near the equator, where the trade winds of the Northern and Southern Hemispheres come together.
What causes ITCZ to move?
The shifting of ITCZ is the result of the Earth’s rotation, axis inclination and the translation of Earth around the Sun. Seasons are the result of this. ITCZ moves toward the hemisphere with most heat, wich are either hemisphere summers.
What are the characteristics of ITCZ?
The Intertropical Convergence Zone (ITCZ) lies in the equatorial trough, a permanent low-pressure feature where surface trade winds, laden with heat and moisture, converge to form a zone of increased convection, cloudiness, and precipitation.
How is India’s climate?
India is home to an extraordinary variety of climatic regions, ranging from tropical in the south to temperate and alpine in the Himalayan north, where elevated regions receive sustained winter snowfall. The nation’s climate is strongly influenced by the Himalayas and the Thar Desert.
What is the mechanism of Indian monsoon?
Indian Monsoons are Convection cells on a very large scale. They are periodic or secondary winds which seasonal reversal in wind direction. India receives south-west monsoon winds in summer and north-east monsoon winds in winter.
