Abstract

Abstract

The mid-Holocene (6 000 years before present) North Atlantic Oscillation (NAO) is studied from the results of four ocean-atmosphere coupled models in the Paleclimate Modeling Intercomparison Project Phase 2 (PMIP2). Using winter North Atlantic sea level pressure (SLP), this paper analyze sea level pressure changes in the North Atlantic during the mid-Holocene compared to pre-industrial (1750 AD) control runs and calculate the NAO index of present and mid-Holocene. There is considerable variation in mean SLP (DJF) between 6 ka and 0 ka across models. Features common to all models include a stronger subtropical high pressure center, a deeper Icelandic low and a tendency toward an increased latitude gradient in mean SLP, and therefore a more positive NAO regime during the mid-Holocene compared to present day. The principal structural of NAO was captured well from all of the models through Empirical orthogonal function (EOF) analyses of North Atlantic sea level pressure in winter time (DJF). There is a robust cross-model change in the variance of the NAO time series. In NAO positive phase, the time lasts 10%~30% longer during the mid-Holocene,especially 29.3% longer in MIROC3.2. Although the amplitude of NAO variability show no greater during the mid-Holocene, it can still be found a more positive NAO from all models. Proxy based reconstructions of the NAO indicate a more positive NAO regime during the Mid-Holocene compared to present day. Simulated NAO variability corresponds fairly closed to proxy-based NAO reconstructions. The Multi-Taper Method of Spectrum Analysis shows that there are three- to five- year quasi-cycles in the NAO index at present and three- year quasi-cycles during the mid-Holocene. NAO plays an important role in the Asian winter warming during the mid-Holocene. The positive SST anomalies in mid-latitude North Atlantic might lead to a more positive NAO during the Mid-Holocene.
