New publication MONGOLIAN CYCLONES DRIVE DUST ACTIVITY FAR BEYOND THE GOBI DESERT
Feifei Mu and Stephanie Fiedler of the ALIC²E group have published a new study on how Mongolian cyclones influence dust activity in the Taklamakan Desert. The study reveals previously overlooked impacts of Mongolian cyclones on dust emissions far beyond their well-known influence on the Gobi Desert.
Mongolian cyclones are an important driver of severe spring dust events in East Asia. While their role in mobilizing dust from the Gobi Desert is well established, their influence on the Taklamakan Desert, located much farther west, has received far less attention. The results show that cold-air intrusions in the wake of Mongolian cyclones enhance near-surface winds in the Taklamakan Desert and contribute 15–25% of its spring dust emissions. These cold-air intrusions also favor the development of anomalously strong nocturnal low-level jets, which account for 10–15% of spring dust emissions.
The findings illustrate that Mongolian cyclones can remotely influence mesoscale atmospheric processes and enhance dust mobilization in the Taklamakan Desert. This newly identified connection between Mongolian cyclones, cold-air intrusions, and nocturnal low-level jets adds an important piece to the puzzle of dust activity and its impacts on air quality in western China.
