For a proper analysis of the concept of national integration it is necessary to know the meaning of certain concepts. The first and foremost concept is the term integration itself which may be defined as “a process of … Read moreChallenges of National Integration

 Climatic changes

    It is the long term change in the statistical distribution of weather patterns over periods of time Though it has been happening naturally for millions of years, in recent years it has accelerated due to anthropogenic causes and has been causing global warming. UNFCCC defines climate change as – “a change of climate … Read more Climatic changes

 Global warming

  An increase in the average temperature of Earth’s near surface air and oceans since the mid-20th century 4th assessment report of IPCC: global temperature increased 74+0.18 degree C during the 20th century. Caused by greenhouse gases Water vapour, Co2, Methane, Nitrous Oxide, Ozone, CFCs (in order of abundance) Since the industrial revolution, the burning of fossil fuels has increased … Read more Global warming

Greenhouse effect

  The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. It is the process by which radiation from a planet’s atmosphere warms the planet’s surface to a … Read moreGreenhouse effect

Tropical and temperate cyclones

    The atmospheric disturbances which involve a closed circulation about a low pressure centre, anticlockwise in the northern atmosphere and clockwise in the southern hemisphere are called cyclones. They fall into the following two broad categories: (a) Extra-tropical or Temperate and (b) tropical cyclones. (a) Temperate Cyclones Temperate cyclones are formed along a front … Read moreTropical and temperate cyclones

 Air masses and fronts

  Airmasses   An airmass is a large body of air with relatively uniform thermal and moisture characteristics. Airmasses cover large regions of the earth, typically several hundred thousand square kilometers. Airmasses can be as deep as the depth of the troposphere or as shallow as 1 to 2 km. Airmasses form when air remains … Read more Air masses and fronts

 Horizontal and vertical distribution of temperature, inversion of temperature

  The temperature is the measurement in degrees of how hot (or cold) a thing (or a place) is. The temperature of the atmosphere is not same across the Earth. It varies in spatial and temporal dimensions. The temperature of a place depends largely on the insolation received by that place. The interaction of insolation … Read more Horizontal and vertical distribution of temperature, inversion of temperature

 Insolation,heat budget of the earth

    The ultimate source of atmospheric energy is in fact heat and light received through space from the Sun. This energy is known as solar insolation. The Earth receives only a tiny fraction of the total amount of Sun’s radiations. Only two billionths or two units of energy out of 1,00,00,00,000 units of energy … Read more Insolation,heat budget of the earth
