Laugh and be merry Tnpsc

Laugh and be merry, remember, better the world with a song,
Better the world with a blow in the teeth of a wrong.
Laugh, for the time is brief, a thread the length of a span.
Laugh and be proud to belong to the old proud pageant of man. -4

Laugh and be merry: remember, in olden time.
God made Heaven and Earth for joy He took in a rhyme,
Made them, and filled them full with the strong red wine of His mirth
The splendid joy of the stars: the joy of the earth. -8

So we must laugh and drink from the deep blue cup of the sky,
Join the jubilant song of the great stars sweeping by,
Laugh, and battle, and work, and drink of the wine outpoured
In the dear green earth, the sign of the joy of the Lord. -12

Laugh and be merry together, like brothers akin,
Guesting awhile in the rooms of a beautiful inn,
Glad till the dancing stops, and the lilt of the music ends.
Laugh till the game is played; and be you merry, my friends. – 16

Women’s Rights Tnpsc

Women’s Rights by Annie Louisa Walker

You cannot rob us of the rights we cherish,
Nor turn our thoughts away
From the bright picture of a “Woman’s Mission”
Our hearts portray.

We claim to dwell, in quiet and seclusion,
Beneath the household roof,–
From the great world’s harsh strife, and jarring voices,
To stand aloof;–

Not in a dreamy and inane abstraction
To sleep our life away,
But, gathering up the brightness of home sunshine,
To deck our way.

As humble plants by country hedgerows growing,
That treasure up the rain,
And yield in odours, ere the day’s declining,
The gift again;

So let us, unobtrusive and unnoticed,
But happy none the less,
Be privileged to fill the air around us
With happiness;

To live, unknown beyond the cherished circle,
Which we can bless and aid;
To die, and not a heart that does not love us
Know where we’re laid.

A Psalm of Life Tnpsc

Tell me not, in mournful numbers,
     Life is but an empty dream!—
For the soul is dead that slumbers,
     And things are not what they seem.

Life is real! Life is earnest!
     And the grave is not its goal;
Dust thou art, to dust returnest,
     Was not spoken of the soul.

Not enjoyment, and not sorrow,
     Is our destined end or way;
But to act, that each to-morrow
     Find us farther than to-day.

Art is long, and Time is fleeting,
     And our hearts, though stout and brave,
Still, like muffled drums, are beating
     Funeral marches to the grave.

In the world’s broad field of battle,
     In the bivouac of Life,
Be not like dumb, driven cattle!
     Be a hero in the strife!

Trust no Future, howe’er pleasant!
     Let the dead Past bury its dead!
Act,—act in the living Present!
     Heart within, and God o’erhead!

Lives of great men all remind us
     We can make our lives sublime,
And, departing, leave behind us
     Footprints on the sands of time;

Footprints, that perhaps another,
     Sailing o’er life’s solemn main,
A forlorn and shipwrecked brother,
     Seeing, shall take heart again.

Let us, then, be up and doing,
     With a heart for any fate;
Still achieving, still pursuing,
     Learn to labor and to wait.

Inter-state river linkages in India

Inter-State River Linkages

Inter-State river linkages is a hot topic in India for several years, especially in the Southern States of the Indian Union. A large number of rivers in South India are non-perennial and water shortages are alarming offseason and in summer.

This topic is a hot topic across the world. The present situation in India is alarming as floods are wreaking havoc in the Northeast and Eastern India and drought is looming in large parts of the Indian Sub-Continent.

Also, many states in Indian Union oppose the inter-basin transfer of waters from the surplus to deficit basins.

The Indian State, Punjab gone one step further by passing a Bill terminating all the previous agreements and accords on river waters and thereby affecting water supply in the neighboring states.

The Punjab action has triggered protests and raised a core issue of national importance.

  • Conflict of interest is the normal state of affairs in a reality where the river flows physically link upstream and downstream users and uses.
  • The issues are complex and linkages are many. But instead of sorting out the differences, of late, water endowed States have been resorting to legal gimmickry while playing to the political galleries, in their bid to prevent the use of waters flowing through their territories by their water deficit neighbours.
  • Kerala has passed a Bill in this regard recently and Karnataka had issued an ordinance on the Cauvery waters some time back. In all these cases, reference has been made to the sovereign rights of the States as enshrined in the Constitution.
  • If other water surplus States take the cue from these instances and act arbitrarily, the consequences of such developments in terms of India’s unity and integrity would be disastrous.
  • Hence the demand has been gaining momentum in the last few years for the Central government to transfer the subject of “Water” from the “State List” to the “Union List” or “Concurrent List” to arrest the further deterioration in water-related issues.
  • In the Constitution, “Water, that is to say, water supplies, irrigation and canals, drainage and embankments, water storage and water power,” is a matter contained in Entry 17, List II (State List).
  • Hence the State legislatures have full powers to legislate under this provision on all water-related matters including their regulation and development. However, this Entry is subject to the provision of Entry 56, List I (Union List) which authorises Parliament to enact laws for the regulation and development of interstate rivers and river valleys Entry 56 under Union List reads as under:
  • Regulation and development of interstate rivers and river valleys to the extent to which such regulation and development under the control of the Union are declared by Parliament by law to be expedient in the public interest.
  • In the past, the Centre had enacted overriding laws using constitutional powers on many subjects such as industry and business, which are included in the State List.
  • However, at present any constitutional amendment particularly in the emotive issue of water does not seem possible. Another view that has gained currency is that without any constitutional amendment, the Centre can deal with interstate rivers by empowering itself under the available provisions (Entry 56, List I).
  • Against the above background, any change in the scheme of the Constitution has to be ruled out and instead the Centre has to pass laws to deal with interstate rivers more effectively as they contribute more than 85 per cent of the water resources of the country.
  • The National Commission for Integrated Water Resources Development Plan had also recommended such an approach (September 1999).
  • Consultative Mechanism: Apart from enacting laws to empower itself for the control and regulation of interstate rivers, there is also a need for the Centre to set up CentreState consultative mechanisms for effectively sorting out water-related concerns.
  • The purpose is to secure a proper tie between problems and their main causes on the one hand and technology and governance perspectives of the problem- solving on the other.
  • Further, a National Water Authority (NWA) as an apex body to concern itself with the development and management of interstate rivers supported by a River Basin Organisation for each interstate river needs to be set up on similar lines as in Australia and France.
  • The River Boards Act (1956) has to be suitably amended to create these institutions.
  • It must be remembered that the development of effective solutions to water problems depends more on governance.
  • Hence it is essential for the Centre to empower itself to take over the interstate rivers for providing better regulation and management of the water resources available in the country and put a stop to the fissiparous tendencies recently demonstrated.

And
gilded honour shamefully misplac’d,
And
maiden virtue rudely strumpeted,
And
right perfection wrongfully disgrac’d,
And
strength by limping sway disabled
And
art made tongue-tied by authority,
And
folly – doctor-like – controlling skill,
And
simple truth miscall’d simplicity,
And
captive good attending captain ill” Sonnet 66 by William Shakespeare.

While I have eyes to seeB
And having none, yet I will keepA
A heart to weep for theeB

Koeppen’s Climate classification India Upsc

Koeppen recognized five major climatic groups, four of which are based on temperature and one on precipitation.

  • A (tropical)
  • B (dry)
  • C (temperate)
  • D (continental)
  • E (polar)
Koeppen's Climate classification India
Koeppen’s Climate classification India By Beck, H.E., Zimmermann, N. E., McVicar, T. R., Vergopolan, N., Berg, A., & Wood, E. F. – “Present and future Köppen-Geiger climate classification maps at 1-km resolution”. Nature Scientific Data. DOI:10.1038/sdata.2018.214., CC BY 4.0, https://commons.wikimedia.org/w/index.php?curid=74674086

Koeppen’s classification of climate developed by V.Koeppen. This classification identified a close relationship between the climate and the distribution of vegetation. V.Koeppen selected some values of temperature, precipitation and related them to the distribution of vegetation, and used these values for classifying the climates.

This classification is an empirical classification that is based on mean annual, mean data of temperature, and precipitation data. In this classification, Koeppen introduced the use of capital and small letters to designate climatic types and groups.

Koeppen’s classification is modified over time after it is introduced in 1918. This classification is still in use and it is the most popular one. By this classification, there are 5 Major Climatic groups. Out of these five, four of them are temperature and one is precipitation based.

GroupCharacteristics
A – Tropical The average temperature of the coldest month is  18° C or higher
B – Dry ClimatePotential evaporation exceeds precipitation
C – Warm TemperateThe average temperature of the coldest month of the Mid-latitude climates years is higher than minus  3°C but below 18°C
D – Cold Snow Forest ClimatesThe average temperature of the coldest month is minus  3°C or below 18°C
E – Cold Climates The average temperature of all months is below 10°C
H – High LandCold due to elevation

The capital letters: A, C, D, and E delineate humid climates and B is a dry climate. The climatic groups are further subdivided into types. The types are designated by small letters. The types are based on the seasonality of temperature characteristics and precipitation.

The seasons of dryness are designated by small letters such as f, m, w, and s. Where

f – No Dry Season

m – monsoon climate

w – winter dry season

s – summer dry season

The small letters a, b, c, and d refer to the degree of severity of temperature. The B-Dry Climates are then subdivided using the capital letters S for Stepple or Semi-Arid and W for deserts. The distribution of climatic groups is shown below:

A – Tropical Humid

  • Tropical Wet (Af) – No dry season
  • Tropical Monsoon (Am) – Monsoonal, short dry season
  • Tropical Wet and dry (Aw) – Winter dry season

B – Dry Climate

  • Subtropical steppe (BSh) – Low Lattitude semi arid or dry
  • Subtropical dessert (BWh) – Low-Lattitude arid or dry
  • Mid-lattitude steppe (BSk) – Mid-Lattitude semi arid or dry
  • Mid-lattitude dessert (BWk) – Mid-Lattitude arid or dry

C-Warm Temperate (Mid-Lattitude) Climates

  • Humid subtropical (Cfa) – No dry season, warm summer
  • Mediterranean (Cs) – Dry Hot summer
  • Marine West Coast (Cfb) – No dry season, warm and cool summer

D-Cold Snow-Forest Climates

  • Humid Continental(Df) – No dry season, severe winter
  • Subarctic(Dw) – Winter dry and very severe

E-Cold Climates

  • Tundra (ET) – No true summer
  • Polar Ice Cap (EF) – Perennial Ice

H-Highland

  • Highland (H) – Highland with snow cover

Group A: Tropical Humid Climates

This climate exists between the Tropic of Cancer and the Tropic of Capricorn. In Tropical humid climates, the sun is overhead throughout the year and there is the presence of Inter-Tropical Convergence Zone (ITCZ).

This makes the climate hot and humid. Also, in this region, the annual range of temperature is very low, and annual rainfall is high. The tropical group is divided into three types name:

  • Af – Tropical wet Climate
  • Am – Tropical Monsoon Climate
  • Aw – Tropical Wet and dry Climate

Af – Tropical Wet Climate

This climate is found in regions near the equator. Ex: Amazon Basin in South America, Western Equatorial Africa, and the islands of East Indies. These regions receive good rainfall every month of the year. Also, there are thundershowers in the afternoon.

The temperature is uniformly high and the annual range of temperature is negligible. The maximum temperature on any day is around 30°C while the minimum temperature is around 20°C.

This region is characterized by tropical evergreen forest with dense canopy cover. Also, a huge variety of biodiversity is found in this climatic region.

Tropical Monsoon Climate (Am)

This climate is found over the Indian sub-continent. Some of the other regions having Tropical Monsoon Climate (Am) are the North-Eastern Part of South America and Northern Australia. In this region, heavy rainfall occurs mostly in summer and has dry winter.

Tropical Wet and Dry Climate (Aw)

This climate is found in the north and south of Af-type climate regions. This borders with a dry climate on the western part of the continent and Cf or Cw on the eastern part. Extensive Aw climate is found in the north and south of Amazon forest in Brazil and adjoining part of Bolivia and Paraguay in South America, Sudan, and south of Central Africa.

The annual rainfall in Aw climate is less than Af and Am climate types and is variable also. The wet season is shorter and the dry season is longer. Also, the drought is more severe. In this climatic zone, the temperature is high throughout the year and the diurnal range of temperature is the greatest in the dry season.

Deciduous forest and tree-shredded grasslands are found in this Aw climate.

Dry Climates: B

This climate is characterized by very low rainfall. As a result, this region does not receive adequate rainfall for the growth of plants. These climates cover a large area of the earth, that extends over the large latitudes from 15° – 60° north and south of the equator.

At the low latitudes from 15° – 30°, where is an area of subtropical high? Here the subsidence and inversion of temperature do produce any precipitation. The western margin of the continents, adjoining the cold current, particularly over the west coast of South America.

These climates extend more towards the equator and occur on the coastland. In middle latitudes,
from 35° – 60° north and south of the equator. Also, this climate is confined to the interior of continents where there are maritime humid winds and do not reach.

Also found in the areas surrounded by mountains.

B(Dry Climate is divided into Steppe or Semi-Arid Climate (BS) and desert climate (BW). This climate is further subdivided as subtropical steppe (BSh) at latitudes from 15° – 35° and mid-latitude steppe (BSk) and mid-latitude desert (BWk) at latitudes between 35° – 60°.

Subtropical Steppe (BSh) and Subtropical Desert (BWh) Climates

Subtropical steppe (BSh) and subtropical desert (BWh) have common characteristics in precipitation and temperature. It is located in the transition zone between humid and dry climates, subtropical steppes get slightly more rainfall than the desert.

This rainfall is good enough for the growth of sparse grasslands. This rainfall in both climates is highly variable. This differential rainfall affects life in the steppe more than in the desert. This causes frequent famines.

In the desert, there are short intense thundershowers in deserts. These showers are ineffective in retaining soil moisture. The Summer experiences maximum temperature. Fog is common in coastal deserts bordering cold currents.

Al Aziziyah, recorded the highest shade temperature of 58° C. Also the annual and diurnal ranges of temperature are also high.

Warm Temperate (Mid-Latitude) Climates-C

This climate extends from 30° – 50° of latitude, particularly eastern and western margins of the continents. This climate has warm summers with mild winters. This climate is grouped into four types:

  • Humid Subtropical i.e Dry in Winter and Hot in Summer (Cwa)
  • Mediterranean (Cs)
  • Humid Subtropical i.e No dry season and mild winter (Cfa)
  • Marine West Coast Climate (Cfb)

Humid Subtropical Climate (Cwa)

This climate occurs poleward of Tropic of Cancer and Capricorn. It is mainly found in North Indian Plains and South China interior plains. This climate is the same as the Aw climate except for the temperature in winter is warm.

Mediterranean Climate (Cs)

Mediterranean climate found around Mediterranean sea. It is along the west coast of the continents in the subtropical latitudes between 30° – 40° latitudes. Example: Central California, Central Chile, along the coast in South Eastern and South Western Australia.

These regions are under the direct influence of a subtropical high in summer and also under the direct influence of westerly wind in winter. Here monthly average temperature in summer is around 25° C and in winter it is below 10°C.

And also the annual rainfall is between 35 to 90 cm.

Humid Subtropical (Cfa) Climate

This climate type exists in the eastern parts of the continent in subtropical latitudes. Here the air masses are usually unstable. As a result, it causes rainfall throughout the calendar year.

Example: Eastern US, South and Eastern China, Southern Japan, North-eastern Argentina, coastal South Africa, and east coast Australia.

In these regions, the annual rainfall ranges from 75-150 cm. Also here common things are thunderstorms in Summer and also frontal precipitation in winter. Here the mean monthly temperature in summer is around 27°C and in winter it varies from 5°-12° C.

The daily range of temperature is small.

Marine West Coast Climate (Cfb)

This climate is located poleward from the Mediterranean climate on the west coast of the continent. Example: North-Western Europe, West Coast of North America, North of California, Southern Chile, Southeastern Australia, and New Zealand.

Because of the influence of the sea, the temperature is moderate. In Winter, the temperature is warmer than for its latitude. The average temperature in the summer is between 15°-20° C. The average temperature in Winter is 4°-10°C.

Also, the annual and daily ranges of temperature are very little. Rainfall occurs throughout the year and it ranges 50-250 cm.

Cold Snow Forest Climates (D)

These climates are found in the large continental area in the northern hemisphere between 40°-70°. Example North Latitudes in Europe, Asia, and North America. This climate type is divided into two types:

  • Df – Cold Climate with humid winter
  • Dw – Cold Climate with Dry winter

Here the severity of winter is more in higher latitudes.

Cold Climate with Humid Winters (Df)

This occurs poleward of the marine west coast and mild latitude steppe. The winters in these areas are cold and snowy. And also frost-free season is very short.

Also, the annual temperature range is high. Here the weather changes are sudden, unexpected, and also short. The winters are more severe poleward.

Cold Climate with Dry Winters (Dw)

This climate occurs mostly in Northeastern Asia. The winters are anti-cyclone. Its weakens in summer sets in monsoon, reversal of wind in this region. In Polewards, the temperature in summer is low. In the winters, the temperature is extremely low.

Most locations experience, below freezing point temperature for almost seven months in a year. Precipitation occurs in the summer and the annual precipitation is very low and it is between 12-15 cm.

Polar Climates (E)

This climate exists poleward, which is beyond 70° latitude. Polar climates are of two types:

  • Tundra(ET)
  • Ice Cap (EF)

Tundra Climate (EF)

The ice cap climate (EF), is found over interior Greenland and Antarctica. The temperature is below freezing point even in the summer. Also, this area receives very precipitation.

The ice sheet breaks, because of the accumulation of snow and ice and the mounting pressure. These ice sheets move as icebergs, floats in the Arctic and Antarctic waters.

Tundra Climate (ET)

In this climate their different types of vegetation such as low-growing mosses, lichens, and flowering plants. This region has permafrost and the soil is frozen permanently. The climate has only a short growing season.

The water logging supports only low-growing plants. The tundra regions have a very long duration of daylight, during the summer.

Highland Climates (H)

This climate is found in high climates. Here are there occurs large changes in mean temperature that occur over short distances. The precipitation types and the intensity of precipitation vary spatially across the high lands.

Also, there is vertical zonation of layering of climatic types with elevation in the mountain.
