Calm wind conditions from Wednesday were likely to make the pollution worse even as Delhi was expected to get light rain on Thursday. “Local surface winds were relatively strong on Tuesday, leading to an improvement but the AQI remained within the ‘very poor’ category. On December 1 (Wednesday) and 2 (Thursday), winds are likely to be calm, reducing ventilation and leading to deterioration in the air quality,” said the System of Air Quality and Weather Forecasting And Research.
