Where is ITCZ now? Although it remains near the equator, the ITCZ moves farther north or south over land than over the oceans because it is drawn toward areas of the warmest surface temperatures. The location of the ITCZ can vary as much as 40° to 45° of latitude north or south of the equator on land.
What are advantages of monsoons?
Advantages: Monsoon rains give a good beneficiary for the farmers and agriculture. The rainfall helps in storing water for irrigation, electric power and drinking. A proper usage of monsoon leads to the prosperity for agriculture and everyone.
What is the possible effect of ITCZ?
Effects on weather
Longer term changes in the intertropical convergence zone can result in severe droughts or flooding in nearby areas. In some cases, the ITCZ may become narrow, especially when it moves away from the equator; the ITCZ can then be interpreted as a front along the leading edge of the equatorial air.
Why is ITCZ important?
The ITCZ follows the sun in that the position varies seasonally. It moves north in the Northern Hemisphere summer and south in the Northern Hemisphere winter. Therefore, the ITCZ is responsible for the wet and dry seasons in the tropics.
Is the ITCZ high or low pressure?
The ITCZ is characterized by low atmospheric pressures (low intertropical pressures), as a consequence of the upward movement induced by the trade winds convergence. It results in high atmospheric pressure in the upper troposphere.
Are monsoons good or bad?
Monsoons are both helpful and harmful.
Although we often associate monsoons with harmful and destructive rain storms, the rains they bring are important for crop production. Summer monsoons in Asia are essential to bring enough water to the area to grow rice and other crops.
What are three benefits of living in a region with monsoons?
Advantages:
- Monsoon rains give a good beneficiary for the farmers and agriculture.
- The rainfall helps in storing water for irrigation, electric power and drinking.
- A proper usage of monsoon leads to the prosperity for agriculture and everyone.
- Specific crops-rice and tea-depend only on monsoon rainfall.
Can a monsoon cause wildfire?
These lightning busts can lead to multiple fire ignitions that can overwhelm local firefighting resources. Sometimes fires ignited from one of these thunderstorm patterns can lay undetected and smolder for several days.
What do you notice whenever ITCZ happens?
The rising air produces high cloudiness, frequent thunderstorms, and heavy rainfall; the doldrums, oceanic regions of calm surface air, occur within the zone. … The ITCZ shifts north and south seasonally with the Sun.
Which country is mostly affected by the ITCZ?
In eastern Asia, the ITCZ may propagate up to 30 degrees north of the Equator. In January, over the Atlantic, the ITCZ generally sits no further south than the Equator, but extends much further south over South America,
Southern Africa, and Australia
.

Does the Philippines belong to the ITCZ?
Philippines: Inter Tropical Convergence Zone (Itcz)
Why does air subside at latitude 30 degrees in both hemisphere?
The air sink at 30 degree latitude as it is very cool enough at that time. Cooler air will have a higher density which will make the air to sink to the Earth surface create a high pressure area.
What countries are affected by ITCZ?
In January, over the Atlantic, the ITCZ generally sits no further south than the Equator, but extends much further south over
South America, Southern Africa, and Australia
. Over land, the ITCZ tends to follow the sun’s zenith point.

What is another name for the ITCZ?
Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator. … And that’s why they call it the doldrums.
What does C in the ITCZ stand for?
The Inter Tropical Convergence Zone, or ITCZ, is a belt of low pressure which circles the Earth generally near the equator where the trade winds of the Northern and Southern Hemispheres come together.
What are advantages and disadvantages of monsoons?
The monsoons bring much-needed moisture into the desert region of the Southwest. During May and June, the area typically suffers from drought conditions. The seasonal rains make it possible for agriculture, forests and inhabitants of the region to store water for the next dry cycle of the climate.
Why are scientist trying to learn more about and predict monsoon?
“Improved predictions of the monsoon, especially its sub-seasonal extremes, could help save lives and reduce their impacts on South Asia’s population, agriculture and the economy.” … The scientists also offer insights for climate and weather scientists to better predict and prepare for a changing, unpredictable monsoon.
Where are monsoons found?
Monsoons are most often associated with the Indian Ocean. Monsoons always blow from cold to warm regions. The summer monsoon and the winter monsoon determine the climate for most of India and Southeast Asia. The summer monsoon is associated with heavy rainfall.
What are the disadvantages and advantages of monsoons?
The monsoons bring much-needed moisture into the desert region of the Southwest. During May and June, the area typically suffers from drought conditions. The seasonal rains make it possible for agriculture, forests and inhabitants of the region to store water for the next dry cycle of the climate.
What are disadvantages of monsoons?
Because regions with a monsoon climate have distinctly wet and dry seasons, they are prone to floods and droughts, both of which are hazardous to health. During summer monsoons, heavy rainfall can cause flooding.
Why would farmers welcome the monsoons?
The monsoon delivers about 70 percent of India’s annual rainfall and is critical for crops such as rice, cane, corn, cotton and soybeans, as nearly half of the country’s farmland lacks irrigation. … The arrival of the monsoon rains brings not only much needed water for crops, but welcome relief from the searing heat.
Did the rain help the wildfires?
Cooler temperatures, rain help B.C. firefighting effort, but relief may be short-lived. Overnight rain helped slow the growth of some of B.C.’s biggest wildfires, even as thousands of properties remain on evacuation alert.
Will rain Help wildfires?
Depending on exactly how much rain will fall, the precipitation could provide a much-needed reprieve for fire crews and allow them to make more progress on the wildfires, especially the White Rock Lake fire, where more rain is expected to fall.
Can fire cause storms?
Sometimes, wildfires can create their own weather. Pyrocumulonimbus are an explosive storm cloud actually created by the smoke and heat from a wildfire. Some of the ferocious wildfires this summer in the West have spawned fire whirls.
