China, like United States and European nations will suffer the return of more heat waves over the next 10 days from east to west, with some coastal cities already on their highest alert level and inland regions warning of dam failure risks because of melting glaciers.
A sharp temperature spike is expected on Saturday, before building up into heat waves, defined as periods of atypically hot weather of three days or more. This Saturday is the day of the “big heat” in the Chinese Almanac based on the lunar calendar.
The hot spell is expected to be similar in scope to heat waves from July 5 to 17, but more regions could be hit by temperatures of 104 degrees Fahrenheit or higher, Fu Jiaolan, chief forecaster at the National Meteorological Center, told state media.
Some cities in Zhejiang province, home to many factories and exporters, on Friday issued red alerts, the highest in a three-tier warning system, forecasting temperatures of at least 104 degrees in the next 24 hours.
The load on the national power grid could reach a new high this summer as demand for air-conditioning by homes, offices and factories surges, with safe operation facing “severe tests,” the Ministry of Emergency Management warned on Friday.
Leo Zhang, president of chemical product maker Sika China said that for all of the factories in China and in Shanghai we have regulations that need to be followed. Every year we do things to make the work more comfortable, for example giving workers ice creams when it gets too hot.
