Shanghai Meteorological Observatory released a new round of high temperature warning Sunday after the east China metropolis has endured four days with the temperatures above 33 degrees Celsius.

Controlled by the subtropical high barometric pressure, the temperature in downtown Shanghai was reported at more than 35 degrees Celsius Sunday.

According to the observatory, Shanghai has already suffered four rounds of continuous high temperature weather this summer, with the top high temperatures above 35 degrees Celsius.

The high temperature once again brought great pressures to the city's power supply.

The municipal government temporarily changed the working schedule of some heavy power-consuming enterprises and demanded the temperature of air conditioners in government institutions and hotels be set at 26 degrees Celsius.

The observatory said Shanghai would have a strong rainfall around Monday and would suffer another round of high temperature lasting about five to six days after the rainfall.
