摘要
本文对西北太平洋主要洋流区之间的海温距平差与副热带高压各特征量进行相关分析,讨论了由于南北海温距平差异而造成副高异常的可能机制。通过分析,给出副高异常年西北太平洋主要洋流区海温距平场的不同分布,指出影响夏季副高异常的关键海域及最佳时段,为预报夏季副高各特征量的变化趋势提供了一种途径。
A correlation analysis is made of sea surface temperature anomaly (SSTA) differences for major ocean current regions in the northwest Pacific and individual characteristic quantities for summertime subtropical high. Then a possible mechanism is discussed for the subtropical high anomaly caused by north-south difference in SSTA. By giving different SSTA distributions for the current regions in years with anomalous subtropical high and isolating key regions and optimum time intervals for the effects exerted on the high, this work offers a way of forecasting its characteristic quantities.
