Establishment of the low-level wind anomalies over the western North Pacific during ENSO development Chia Chou Environmental Change Research Project Institute of Earth Sciences Academia Sinica, Taiwan ― Establishment ― Eastward movement
Intermediate complexity climate model QTCM (Quasi-equilibrium Tropical Circulation Model) ― constrained by quasi-equilibrium thermodynamic closures, such as Betts-Miller convective scheme ― simple land surface model: moisture and energy budget in one surface layer Forced by prescribed ENSO SST
Conclusions • Mechanism of the establishment: – the horizontal advection of moist static energy –local SST anomalies • Eastward movement: – winter monsoon flow coupled with atmo. T ́ induced by ENSO – mean q and T coupled with wind anomalies over the WNP
