Heat wave hits Beijing with record-breaking temperatures and health warnings.

Beijing and parts of northern China are experiencing record temperatures, with authorities urging people to limit their time outdoors. The Nanjiao observatory in southern Beijing on Saturday for the first time recorded temperatures above 40 degrees Celsius (104 degrees Fahrenheit) for a third consecutive day, prompting authorities to issue “red” alerts for extreme weather. Chinese meteorologists say the current heat wave was caused by warm air masses associated with high-pressure ridges in the atmosphere, compounded by thin cloud covers and long daylight hours around the summer solstice.
