The severe pollution by smog should be swept away as a cold front is expected to arrive in Hangzhou and end the lingering bad weather on Wednesday, according to local forecasters.
Today the air quality index is predicted to be in the 220-240 range, or heavy pollution around three times of the national limit of 75 micrograms per cubic meter. It has been severe pollution for the past five days in the city, with air quality index in 300-500 range.
The cold air will be accompanied by winds and there will be a noticeable decline in smog level.
About 84 flights were delayed for around four hours at Xiaoshan International Airport yesterday because of poor visibility.
Almost all highways around the city were also closed yesterday morning and resumed on some roads in the afternoon.
Today the cold air will bring wind to the city, a key factor to reduce smog. With another cold front coming to the city on Wednesday, the heavy smog will disperse finally, forecasters said.
