Hot days ahead as plum rain season officially ends

AFTER 42 days, the longest and wettest plum rain season in two decades ended yesterday. It will be followed by more hot days with temperatures touching 35 degrees Celsius, the Shanghai Meteorological Bureau said yesterday.

The plum rain season often features several weeks of wet weather and high temperatures. This was the third-longest summer rain season since 1961, 1996 and 1999 (the last two recording 43 days), the bureau said.

The season started on June 9, eight days earlier than usual, and ended 11 days later than average, according to weather authorities. Rainfall was also at historic levels.

As of 8pm on Monday, the average precipitation recorded at meteorological stations in the city was 533 millimeters, 2.4 times the annual plum rain season average and the highest since 2000.

Rainfall recorded at the benchmark Xujiahui meteorological center in downtown Xuhui District was 549.5mm, the third-highest level since 1875. Rainfall recorded at the meteorological station in Baoshan District (686.4mm) set a new record since 1999, the bureau said.

According to the traditional Chinese calendar, the 12th solar term, dashu or “great heat,” will start today and daily high temperatures are expected to reach 35 degrees until Friday.

This week will continue to see precipitation as well. Except for today, rains are expected until the end of the week, especially in the afternoon, the weather bureau said.

The city’s flood prevention office has also geared up for the upcoming typhoon season, as two or three tropical storms are predicted to hit the vicinity of Shanghai this year.

A special flood control drill was performed at the National Exhibition and Convention Center last weekend with personnel from drainage management departments across the city.

To cope with heavy rainfalls during the prolonged rain season, the city’s water bureau and flood prevention office enhanced their overall prevention ability and eliminated hidden risks.

By the end of 2019, Shanghai had a total of 1,418 public drainage pumping stations for rainwater, confluence and sewage. A total of 148 monitoring sites were also established last year in central urban areas to improve real-time monitoring at pump stations.

The flood prevention team, established 10 years ago by the office, has also been upgraded over the years from a small voluntary service team to a multilevel emergency crew capable of coping with 100,000 cubic meters of water per hour.

Currently, there are a total of about 800 emergency personnel and 102 smart pump trucks in the city, which can be dispatched via an intelligent managing system.
