Delhi has seen a marginal dip in the temperature on Thursday morning as the national capital has witnessed light to moderate rain and gusty winds with a speed of 30–40 km/h. This even resulted in an improvement in air quality, which was classified as satisfactory.
The maximum temperature is expected to be around 30°C while the minimum is to be 25°C, which when compared to Wednesday was 33.6°C and 26.4°C respectively.
RK Jenamani, India Meteorological Department (IMD) scientist, said a depression that formed over Odisha and moved towards northwest India sent easterly winds with moisture towards Delhi-NCR and led to a three-day spell of rain. He said, “As this depression has moved closer, we are seeing the effect of these strong easterly winds, which has led to an increase in the speed of surface winds locally. The moisture is also leading to cloudy skies, which has led to a drop in the mercury. “
The intensity of rain will reduce from Friday evening, with no rain expected from September 17 to 20.
An AQI between zero and 50 is considered “good”, 51 and 100 “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor”, and 401 and 500 “severe”. According to the Central Pollution Control Board, the Air Quality Index (AQI) was at 63 on Thursday morning at 7 a.m.
The monitoring agency, System of Air Quality and Weather Forecasting and Research, said on Wednesday that the satisfactory level of AQI is expected to last till Saturday. They said, “For the next three days, peak wind speed is likely to be around 14–29 km/h, causing moderate dispersion and AQI is likely to be within the range of’satisfactory’ due to expected light/trace rain spells.”
