Abstract:
The monthly mean OLR data arc used to analyse the varying laws of the global subtropical high and equatorial ITCZ. The pcrsistense and anomalous features in the heavy flood years over the Changjiang valley is investigated. It is shown that much closer attention to the anomalous clistribution of the global subtropical high in November-Feburary and the intensity of the cumutus in south to the equatorial ITCZ over the low-lafitute oceans in March -June wouldlay a sound foundation to heavy flood forecasting,
