Halley’s Thermal concept: Indian monsoon is because of contrast between Indian Subcontinent and adjoining Indian Ocean. Halley’s theory, suggested in 1686, considers the summer monsoon to be a regional phenomenon. Aerological concept: This was suggested by R. Scherhag in 1948. According to this theory, monsoon circulation develops due to changes in air temperature at all … Read more DMPQ- State the classical theories of the origin of monsoon.

Tropical Cyclone Extra tropical cyclone It has thermal origin and derives its energy from the latent heat of condensation It has dynamic origin involving coriolis force and movement of air masses. The energy of a temperate cyclone depends on the densities of air masses. It is confined to 10o – 300 N and S of … Read more DMPQ- Differentiate between tropical and extra tropical cyclone.

An air mass is a large volume of air in the atmosphere that is mostly uniform in temperature and moisture. Air masses can extend thousands of kilometers across the surface of the Earth, and can reach from ground level to the stratosphere—16 kilometers (10 miles) into the atmosphere. The climates of most regions worldwide are … Read more DMPQ- What do you mean by Air Mass? How is it influence the local climate?

Most known volcanic activity and the earthquakes occur along converging plate margins and mid-oceanic ridges. There is a strikingly close agreement between volcanic and earthquake zones of the earth. The major regions of volcanoes around the world are: Pacific ring of fire:  Pacific Ring of Fire’ is estimated to include two-thirds of the world’s volcanoes.  The major regions … Read more DMPQ: Distribution of volcanoes around the world.

There are several reasons for this. First, the mountain topography in Karnataka is broader than the narrow topography of the Ghats in Maharashtra. Due to the greater width of the mountains, the rain bearing winds have to necessarily travel a longer distance and have more time for the drops to coalesce and precipitate as rainfall, … Read more DMPQ: Western Ghats in Karnataka receive more monsoon rainfall than Maharashtra and Kerala.Explain

A watershed is the geographic area through which water flows across the land and drains into a common body of water – stream, river, lake, or ocean. The watershed boundary follows the highest ridgeline around the stream channels which separates the water flow which may be basically rainwater, groundwater, water from melting snow etc. and … Read more DMPQ- Write a short note on watershed management.

The Himalayan has rendered unique climatic identity to Indian subcontinent. The role played by it is nothing less than a foster mother. It save India from the cold north east trade winds and provide tropical type of climate in the subtropical region. It is not a exaggeration to say that Indian economy is gamble of … Read more DMPQ: The Himalayas has played the important role of a foster mother for the Indians. Discuss

India is the second populous country after china. India has 17.74% of the total world population. The main reason for the high population growth is the high fertility rate which is presently 2.5. It means an Indian women in her reproductive span produces 2.5 offspring on an average. The reasons for high fertility rate are … Read more DMPQ: What are the reasons for high fertility rate in India?

The savanna or sudan climate is a transitional type of climate found between the equatorial forest and the trade winds hot deserts. It is confined within the tropics and is best developed in the sudan where the dry and wet seasons are most distinct, hence its is named sudan climate. Llanos in oronocco basin and … Read more DMPQ: Explain the Savanna type of climate

Temperate cyclones are also known as Extra-tropical cyclone where the term “Extra-tropical” signifies that this type of cyclone generally occurs outside the tropics with a latitude range between 30° and 60°. Characteristics of Temperate Cyclone (Extra-Tropical Cyclones) The Extra-Tropical Cyclones are storm systems emerging in the mid and high latitudes, away from the tropics. They … Read more DMPQ- Write a short note on Extra Tropical Cyclone.
