HONG KONG: China warned communities in its northwestern Xinjiang and nearby regions on Friday (Jun 12) to prepare for “extreme floods” this summer, driven by abnormally high temperatures, heavy rainfall and rapid glacier melt.
Xinjiang’s Taklamakan Desert, China’s largest, experienced its first flood of the year in early June, state broadcaster CCTV reported on Friday, showing footage of water filling the typically arid dunes.
While the Taklamakan has experienced similar floods since 2021, they typically occur in August, when temperatures peak. However, temperatures have surged much earlier this year.
On Jun 12, Xinjiang was 7.3 degrees hotter than average for this time of year, reaching 38°C (100°F), according to Reuters Climate Monitor.
Western and southern Xinjiang have also seen more frequent rainfall recently. Precipitation in some areas has been double or even triple the historical average for early June, CCTV reported.
GLACIERS AND SNOW MELTING
The combination of intense heat and rainfall has triggered the desert floods. Large swathes of glaciers and snowpack in the Tianshan and Kunlun mountains have melted, sending runoff rushing into the Tarim River, China’s longest inland waterway.
The influx caused the river to burst its banks, spilling water into low-lying areas of the desert, the broadcaster said.
While the seasonal floods can temporarily create short-lived oases, experts say they are unlikely to last because the Taklamakan Desert is situated far inland and surrounded by high mountains, so low moisture levels and extreme evaporation will quickly dry out the terrain.
