Delhi experiences warmer nights in early February; air quality declines

Delhi sees warmer nights with minimum temperature at 13.2°C; AQI worsens.

Delhi is experiencing warmer nights earlier in February, with Safdarjung recording a minimum temperature of 13.2°C, three notches above the normal. The IMD forecasts above-normal temperatures for February. Simultaneously, Delhi's air quality has slipped back into the 'Very Poor' category, with an AQI of 305. Similar trends are observed in Noida, while Gurgaon remains in the 'Poor' category. The early rise in night temperatures is attributed to approaching western disturbances.

Background

The phenomenon of rising temperatures and declining air quality in Delhi is linked to broader environmental and meteorological patterns. Understanding these requires looking at the history of environmental regulations and the impact of urbanization. The Air Quality Index (AQI), a key metric for measuring air pollution, has its roots in efforts to standardize pollution reporting across different pollutants. The establishment of the Central Pollution Control Board (CPCB) in 1974 was a significant step towards monitoring and regulating pollution in India. Over the years, various policies and regulations have been introduced to combat air pollution, including the National Clean Air Programme (NCAP). These initiatives aim to reduce particulate matter and improve overall air quality in cities like Delhi. The effectiveness of these measures is often debated, highlighting the complex interplay of economic development and environmental sustainability. Western disturbances, which are extratropical cyclones originating in the Mediterranean region, play a crucial role in influencing weather patterns in North India. These disturbances bring moisture and precipitation, affecting temperature and air quality. The frequency and intensity of western disturbances can vary due to climate change, leading to unpredictable weather patterns. The India Meteorological Department (IMD) is responsible for monitoring and forecasting these weather events.

Latest Developments

Recent developments indicate a growing focus on addressing air pollution through technological interventions and policy reforms. The use of artificial intelligence (AI) and machine learning is being explored to improve air quality forecasting and identify pollution hotspots. Stricter emission norms for vehicles and industries are also being implemented to reduce pollution at the source. However, challenges remain in effectively implementing these measures and ensuring compliance. Public awareness and participation are crucial for the success of air pollution control efforts. The role of state governments and local bodies is also vital in enforcing regulations and promoting sustainable practices. There are ongoing debates about the optimal balance between economic growth and environmental protection. Looking ahead, the focus is on transitioning to cleaner energy sources and promoting sustainable transportation options. The government has set targets for increasing the share of renewable energy in the energy mix and promoting the adoption of electric vehicles. International cooperation and knowledge sharing are also essential for addressing transboundary air pollution issues. The success of these efforts will depend on sustained commitment and coordinated action by all stakeholders.

Frequently Asked Questions

1. What are the key facts about Delhi's warmer nights and air quality decline that are important for the UPSC Prelims exam?

For UPSC Prelims, remember these key facts: Delhi experienced warmer nights in early February, with Safdarjung recording a minimum temperature of 13.2°C, which is three notches above the normal. Also, Delhi's air quality has declined to the 'Very Poor' category, with an AQI of 305.

2. What is the significance of 'Western Disturbances' in the context of Delhi's rising temperatures?

As per the provided information, the early rise in night temperatures is attributed to approaching western disturbances. Western disturbances are weather systems that originate in the Mediterranean region and bring moisture and altered weather patterns to northern India. They can influence temperature and precipitation, leading to warmer nights as observed in Delhi.

3. How does the current situation in Delhi, with warmer nights and declining air quality, impact the common citizens?

Warmer nights can disrupt sleep patterns and increase energy consumption for cooling. Declining air quality can lead to respiratory problems, especially for vulnerable populations like children and the elderly. It can also affect outdoor activities and overall quality of life.

4. What are the recent developments regarding air quality improvement efforts in Delhi?

Recent developments indicate a growing focus on addressing air pollution through technological interventions and policy reforms. The use of artificial intelligence (AI) and machine learning is being explored to improve air quality forecasting and identify pollution hotspots. Stricter emission norms for vehicles and industries are also being implemented to reduce pollution at the source.

5. What is the Air Quality Index (AQI) and why is it important to monitor it?

The Air Quality Index (AQI) is a metric used to measure and report air pollution levels. It's important because it provides a standardized way to understand the level of air pollution and its potential health impacts. In Delhi's case, an AQI of 305 indicates 'Very Poor' air quality, posing significant health risks.

6. Based on the current news, what could be potential government initiatives to tackle the combined problem of rising temperatures and declining air quality in Delhi?

Potential government initiatives could include stricter enforcement of emission norms for vehicles and industries, promotion of public transportation and electric vehicles, expansion of green cover through afforestation, and implementation of measures to reduce dust pollution. Also, public awareness campaigns can help in encouraging responsible behavior.

Practice Questions (MCQs)

1. Consider the following statements regarding the Air Quality Index (AQI): 1. The AQI is a tool used to communicate air quality to the public. 2. An AQI value of 305 indicates 'Moderate' air quality. 3. The Central Pollution Control Board (CPCB) is responsible for monitoring and regulating AQI in India. Which of the statements given above is/are correct?

  • A.1 and 2 only
  • B.1 and 3 only
  • C.2 and 3 only
  • D.1, 2 and 3
Show Answer

Answer: B

Statement 1 is CORRECT: The Air Quality Index (AQI) is indeed used to communicate air quality to the public in an easily understandable way. Statement 2 is INCORRECT: An AQI of 305 falls into the 'Very Poor' category, not 'Moderate'. Statement 3 is CORRECT: The Central Pollution Control Board (CPCB) is the primary body responsible for monitoring and regulating air quality, including the AQI, in India.

2. Which of the following factors contributes to the early rise in night temperatures in Delhi, as mentioned in the news?

  • A.Increased industrial activity
  • B.Approaching western disturbances
  • C.Reduced green cover
  • D.Increased vehicular emissions
Show Answer

Answer: B

The news explicitly mentions that the early rise in night temperatures is attributed to approaching western disturbances. These disturbances bring warmer air and prevent temperatures from dropping significantly during the night.

3. With reference to the Central Pollution Control Board (CPCB), consider the following statements: 1. It was established in 1974 under the Water (Prevention & Control of Pollution) Act, 1974. 2. CPCB coordinates the activities of the State Pollution Control Boards. 3. It advises the Central Government on all matters concerning the prevention and control of air and water pollution. Which of the statements given above is/are correct?

  • A.1 and 2 only
  • B.1 and 3 only
  • C.2 and 3 only
  • D.1, 2 and 3
Show Answer

Answer: D

All three statements are correct. The CPCB was indeed established in 1974 under the Water Act. It coordinates with State Pollution Control Boards and advises the Central Government on matters related to pollution control.
