CHEN Si, JIAN Maoqiu. Propagation of the Quasi-Biweekly Oscillations Related to Rainfall Abnormity in the First Rainy Season over Southern China[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2015,54(3):130-137.DOI:
The relationship between the quasi-biweekly oscillation(QBW: here defined as a 10~25 day oscillation) abnormity of May-June rainfall over southern China and the QBW propagation from the tropics and mid-latitudes is studied based on the composite analysis. The results indicate distinct QBW propagations in different May-June rainfall abnormal cases. The strong QBW rainfall abnormal cases in May in southern China are linked to the QBW propagations not only from the Bay of Bengal but also from the mid-latitudes of northwestern China. However
the weak QBW rainfall abnormal cases in May are just linked to the QBW propagations from the tropics. In June
the strong and weak QBW rainfall abnormal cases in southern China are influenced by the QBW propagations from the Bay of Bengal and from the mid-latitudes,respectively.
