CHINA (CNN) -- Meteorological staff in Hangzhou, the capital of east China's Zhejiang Province, created artificial precipitation on Tuesday, helping ease the continued heat wave that has seared the city since July.
Seven rocket projectiles were launched in Hangzhou's Yuhang District at 15:30 and 16:00 Tuesday afternoon, and around 10 minutes later, rain started to fall.
"The rockets were fired into the sky where they produce a condensation nucleus that generates rainfall when meeting water vapor," said Yang Zhijiang, deputy director of Hngzhou's Yuhang District Meteorological Office.
Currently artificial rainfall has been undertaken in six regions in Zhejing Province, with average temperature from July 1 to July 29 reaching 30.3 degrees Celsius, the highest in 60 years.
Average rainfall, however, was 38 millimeters, less than 30 percent of that of the same period in previous years, and the lowest in 60 years.
The city of Hangzhou has seen rain only three times in July. Some 57 counties, cities or districts in Zhejiang Province are currently classified as experiencing drought conditions, provincial drought monitoring statistics showed on Monday.
