Northen Cities in China Is Experiencing High Temperature

Beijing and parts of northern China are experiencing record temperatures, prompting authorities to issue "red" alerts for extreme weather.
In China's four-tier weather alert system, red indicates the most severe conditions, ones with potential health and safety hazards.
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.
