What is classical theory of monsoon?
Classical Theory: In 1686 the famous Englishman Sir Edmund Hailey explained the monsoon as resulting from thermal contrasts between continents and oceans due to their differential heating. Accordingly, Hailey conceived summer and winter monsoons depending upon the season.
Who gave the classical theory of monsoon?
Sir Edmund Halley’s
Indian Monsoons – Classical Theory: Sir Edmund Halley’s Theory. In summer the sun’s apparent path is vertically over the Tropic of Cancer resulting in high temperature and low pressure in Central Asia. The pressure is sufficiently high over Arabian Sea and Bay of Bengal.
What is monsoon mechanism?
Monsoons are mainly seasonal winds that reverse their direction according to the change in season. The monsoons starts its journey from the sea to the land in summers and from land to the sea during winters, hence, are a double system of seasonal winds.
What is Flohn theory?
The Equatorial Westerly Theory has been propounded by Flohn. He states that the equatorial westerly is the south-west monsoon that is originates because of inter-tropical convergence. The Equatorial Westerly. According to him, the thermal effect as the main reason for the origin of the monsoon.
What are the two types of monsoon in India?
India actually has two monsoons –- the southwest monsoon and the northeast monsoon. The southwest monsoon, which is the main monsoon, comes in from the sea and starts making its way up India’s west coast in early June.
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 the role of ITCZ in Indian monsoon?
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.
Why is monsoon important?
The monsoon is critical for agriculture in the country since nearly 60% of India’s net arable land lacks irrigation. The monsoon delivers about 70% of India’s annual rainfall and determines the yield of several grains and pulses, including rice, wheat, and sugarcane.
What are the main features of monsoon?
Heavy rainfall in summer is the defining characteristic of Monsoon climate. Although, The spatial distribution of rainfall is uneven – some regions may receive heavy rains & floods, while the others will have to be contented with meagre rains, droughts & famines.
What is Jet Stream Theory?
The Jet Stream Theory is a study of a narrow belt of high altitude westerly winds in the troposphere. It’s speed varies from 110 km/h in summer to 184 km/h in winter. This theory was propunded by the Yest. It is driven by air pressure, temperature and moisture differences between one place and another.
What is equatorial westerlies Upsc?
Quick Reference. The westerly winds that sometimes develop within the equatorial trough when the Intertropical Convergence Zone is well north or south of the Equator. The north-easterly or south-easterly trade winds cross the Equator and, because of the reversal of the Coriolis effect, acquire a westerly component.
What are the branches of Indian monsoon?
The two branches of monsoon are Arabian Sea branch and Bay of Bengal branch.
What was the classical theory of the monsoon?
Hailey’s classical theory based on differential heating of land and water as the main driving force of the monsoon winds dominated the scene for about three centuries. However, the monsoons do not develop equally everywhere and the thermal concept of Hailey fails to explain the intricacies of the monsoons.
How does classical organizational theory view an organization?
It takes a rigid as well as a static view of organizations. Most classical theorists view an organization as a closed system with no interaction with its environment. The theory focuses more on the structural and also the technical aspects of organizations. It is based on oversimplified and mechanistic assumptions.
What did the classical writers think about organisation?
The classical writers viewed organisation as a machine and human beings as components of that machine. They were of the view that efficiency of the organisation can be increased by making human beings efficient. Their emphasis was on specialisation and co-ordination of activities.
Is the origin of the monsoon still a mystery?
The origin of monsoons is still shrouded in mystery. Several attempts have been made to explain the mechanism of the monsoons but no satisfactory explanation is available till date. Over the years many mysteries of the monsoons have been unravelled but still much remains to be done.
