Biography

Qian has presented an approach, decomposing the atmospheric variable into temporal climatology and anomaly. The approach helps forecasters understand weather, climate, and general circulation as well as their anomalies. It confirms that the Arctic cell is directly linked to the warming in the high latitudes. Qian has proposed the anomaly-based synoptic chart that can locate weather extremes. Qian has developed an optimal-level dynamical model which can predict most unusual tropical cyclone tracks. Qian has defined the global monsoon domain as the regions where the difference of two pentad mean precipitation rates exceeds 4 mm day−1, which is also influenced by the low-level prevailing wind reversal associated with the cross-equatorial flow.
