【Abstract】 The impact of large-scale circulation conditions from June to October in 2000 on the tropic cyclone activities is analyzed. In 2000 tropic cyclone activities were less than climatic average, the intrinsic reason leading to this lopsided state is the anomaly of large-scale circulation, and it is the anomaly that impacted reducing the number of tropic storm outset and landing in nonactivity phase of tropic cyclone, even debasing the total number of tropic storm in this year. This general circulation anomaly is most obvious in the June and October.更多还原
