What is the meaning of monsoonal trough?
Monsoon Trough is an elongated low-pressure area which extends from heat low over Pakistan to Head Bay of Bengal. This is one of semi-permanent feature of monsoon circulation. Monsoon trough may be a characteristic of east west orientation of Himalayan ranges and north south orientation of Khasi-Jaintia Hills.
What is trough and axis of monsoon?
With the advance of the monsoon this heat low gradually extends eastwards until it forms an elongated low-pressure zone running parallel to the Himalayan mountains in a west to east direction. Meteorologists in India refer to this as the monsoon trough. Its axis is roughly parallel to the Himalayan foothills.
Why ITCZ is called monsoon trough?
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 do I find my monsoon trough?
A trough is a belt of low pressure extending to large area. This trough seen during monsoon period, hence known as Monsoon trough. Features of Monsoon Trough: This trough is located in east west direction from Northwest Rajasthan till the Bay of Bengal.
What is monsoon is also known as?
The Monsoon Zone is a belt of low-pressure air currents that circle the Earth at the Equator. The Monsoon Zone is also known as the Intertropical Convergence Zone (ITCZ). The Monsoon Zone is usually warm and experiences mild winds.
What is monsoon Upsc?
Monsoons are an important chapter in Geography for the UPSC exam. It is a part of the climate section and is very important since the Indian climate is dominated by this phenomenon. It is also significant for the country’s economy since a large part of Indian agriculture is dependent on monsoons.
What is trough and Axis?
When the height contours bend strongly to the south, (as in the diagram below), it is called a TROUGH. Strong troughs are typically preceded by stormy weather and colder air at the surface. Below is an example of a trough in an upper-level height field (red contours). The trough axis is denoted by the purple line.
What is trough weather?
A trough is an elongated area of relatively low pressure extending from the center of a region of low pressure. Air in a high pressure area compresses and warms as it descends. This warming inhibits the formation of clouds, meaning the sky is normally sunny in high-pressure areas. But haze and fog still might form.
Why is ITCZ called doldrums?
Because the air circulates in an upward direction, there is often little surface wind in the ITCZ. That is why sailors well know that the area can becalm sailing ships for weeks. And that’s why they call it the doldrums.
What is equatorial trough?
equatorial trough in American English noun. the quasi-continuous belt of low atmospheric pressure that lies between the subtropical high-pressure belts of the Northern and Southern hemispheres.
In which month monsoon will come?
The monsoon season in most of India lasts from June to September. The wettest months are June and July. The rain starts slowing in August and becomes much less frequent in September.
What are the 2 monsoons system?
The major monsoon systems of the world consist of the West African and Asia–Australian monsoons. The inclusion of the North American Monsoon and South American monsoon with incomplete wind reversal has been debated.
What is the meaning of Monson?
Monson is a town in Hampden County, Massachusetts, United States. The population was 8,560 at the 2010 census. It is part of the Springfield, Massachusetts Metropolitan Statistical Area. The village of Monson Center lies at the center of the town.
What is El Nino Upsc?
El Nino refers to the large-scale ocean-atmosphere climate interaction linked to periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific. It is associated with high pressure in the western Pacific. El Nino adversely impacts the Indian monsoons and hence, agriculture in India.
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. The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and making it buoyant.
What is trough line?
A line along which pressures are lower than in the surroundings and where the cyclonic curvature of the isobars is a maximum.
Do troughs bring stormy weather?
Troughs may be at the surface, or aloft. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift.
What is peak and trough?
The lowest level of the drug in the patient’s body is called the trough level. The peak for a drug is when the level of the drug in the patient’s body is the highest.
What is the difference between ITCZ and doldrums?
Doldrums are calm atmospheric conditions found along equatorial regions from where trade winds continue to rise upward due to intense heating of the earth surface. ITCZ is the zone where trade winds confluences which migrate north and south of the equator with the apparent movement of the sun.
