摘要
Seasonal prediction of Asian-Australian monsoon (A-AM) precipitation is one of the most important and challenging tasks in climate prediction. In this paper, we evaluate the performance of Grid Atmospheric Model of IAP LASG (GAMIL) on retrospective prediction of the A-AM interannual variation (IAV), and determine to what extent GAMIL can capture the two major observed modes of A-AM rainfall IAV for the period 1979–2003. The first mode is associated with the turnabout of warming (cooling) in the Niño 3.4 region, whereas the second mode leads the warming/cooling by about one year, signaling precursory conditions for ENSO.
