Question Q13GS1GS1

How does temperature inversion affect atmospheric conditions & what are its implications for local weather patterns & air pollution levels?

Open scan (p.30)

Main Body

Temperature inversion refers to the trend of increase in the temperature of atmosphere as we move away from earth's surface.

Temperature Inversion & Atmospheric Condition

1Stable air: The movement of air above a particular level is hindered.
2Prevents evaporation
3Huge fog & mist created → Reduces visibility of air
4Very cold local condition → may affect productivity in working performance.

T.I & Local weather pattern

1Very less rainfall: as the Convection is induced.
2Chilling cold & Anticyclonic conditions created.
3Valley inversion in mountain: drainage of cold air in valley knock off the plants from frost damage.

Effect on Air Pollution

1Increases air pollution → As it does not let air particles / pollutants move away (above). → Trapped by warm air lid.

for eg: Bhopal gas tragedy: toxic gases could not escape & remained on ground → causing death.

2Nuclear → fog & mist huge → poor visibility → huge pollution. With Sun rising & temperature increasing T.I vanishes.

It's more prominent in higher latitudes.

With multipronged strategy of the Central and State Governments specially in the last few years, the naxalite problem has been resolved to a large extent in the affected states of the country. However, there are a few pockets in certain states where naxalite problem still persists, mainly due to involvement of foreign countries. Rohit is posted as SP (Special Operations) for the last one year, in one of the districts which is still affected by the naxalite problem. The district administration has taken a lot of developmental works in the recent past in the naxalite affected areas to win the hearts and minds of the people. Over a period of time, Rohit has established an excellent intelligence network to get the real time information regarding the movement of naxalite cadre. To instill confidence in the public and have moral ascendancy over the naxalites, a number of cordons and search operations are being conducted by the police. Rohit, who himself was leading one of the contingents got a message though his intelligence source that about ten hard core naxalites were hiding in a particular village with sophisticated weapons. Without wasting any time, Rohit reached the target village with his team and laid out a foolproof cordon and started carrying out a systematic search. During the search, his team managed to overpower all the naxalites along with their automatic weapons. However, in the meantime, more than five hundred tribal women surrounded the village and started marching towards the target house. They were shouting and demanding the immediate release of insurgents since they are their protectors and saviours. The situation on the ground was becoming very critical as the tribal women were extremely agitated and aggressive. Rohit tried to contact his superior officer, IG (Special Operations) of the state on the radio set and on mobile phone, but failed to do so due to poor connectivity Rohit was in great dilemma since out of the naxalites apprehended, two were not only hard core top insurgents with prize money of & ten lakhs on their heads, but were also involved in a recent ambush on the security forces. However, if he did not release the naxalites, the situation could get out of control since the tribal women were aggressively charging towards them. In that case, to control the situation Rohit might have to resort to firing which may lead to valuable loss of lives _of civilians and would further complicate the situation. (a)What are the options available with Rohit to cope with the situation? (b)What are the ethical dilemmas being faced by Rohit ? (c)Which of the options, do you think, would be more appropriate for Rohit to adopt and why? (d)In the present situation, what are the extra precautionary measures to be taken by the police in dealing with women protesters?
