The maximum and minimum temperatures on Sunday may hover around 33 and 11 degrees Celsius,” an IMD official said.The air quality index (AQI), on a scale of 0 to 500, was ‘poor’ at 225 on Saturday against 171 a day earlier.”Overall AQI indicates ‘upper end of moderate’ air quality. Fine particles contribute about 46% to PM10. For the next three days, surface wind speed (calm; 6 to 10 km/h) and temperature (max 32-33 degrees Celsius; min 10-14 degrees Celsius) are likely to worsen air quality,” stated the System for Air Quality and Weather Forecasting and Research.
