Delhi experienced thick fog on Monday morning with a minimum temperature of 4 degrees Celsius in RK Puram and the Indian Meteorological Department (IMD) issuing an "orange alert". The Air Quality Index (AQI) re-entered the "severe" category on Sunday, leading to the reimposition of restrictions under Stage III of the Graded Response Action Plan (Grap) by the Commission for Air Quality Management (CAQM).
Last week, major parts of the national capital city had gone down to the "very poor" category on the AQI index, leading the central government to roll back Grap stage II, which requires the AQI level to be above the 400- mark. This order was reversed on Sunday as air pollution rose in the national capital.
On Monday, ITO (412), Patparganj (428), Anand Vihar (431), Nehru Nagar (460), Wazipur (410), Jawaharlal Nehru Stadium (41), and RK Puram (439) all fell into the "severe" AQI category. Pusa-IMD (331), Shadipur (372), and DU North Campus (387) were in the "very poor" AQI category.
AQI readings between zero and 50 are considered "good", 51 and 100 "satisfactory", 101 and 200 "moderate", 201 and 300 "poor", 301 and 400 "very poor", and 401 and 500 "severe". AQI readings at or below 100 are considered satisfactory, while levels above 100 are considered unhealthy.
Cold alert in North India
Delhi is currently experiencing a severe winter season, with the IMD issuing an orange alert for Monday, January 15. This indicates a cold wave in the city with dense to very dense fog, and the minimum temperature is expected to drop to 4 degrees Celsius. Homeless individuals are also increasingly seeking refuge in shelters set up by the state government. These shelters offer blankets, beds, hot water, and food throughout the city.
The IMD has also issued a "cold alert" for Uttar Pradesh, Punjab, and Haryana for Monday and Tuesday.
