9313821 McIntyre The goal of this study is to determine if solar forcing alters climate at the millennial time scales with the help of calcareous planktonic and isotopic proxies. This will be done in three steps. First, the response of surface waters of equatorial Atlantic to climate controlled wind variations will be documented. Second, these signals will be compared with time series from other regions to determine if these short period signals are global. Third, a sine wave signal of millennial response of ocean/climate will need constructed which can be used bother for comparison with other records and as a predictive template.

9313821 McIntyre这项研究的目的是确定太阳强迫是否会在千年时间尺度上改变气候，并借助钙质同位素替代物。这将分三步完成。首先，赤道大西洋的表面沃茨的气候控制的风的变化的反应将被记录。其次，这些信号将与其他地区的时间序列进行比较，以确定这些短周期信号是否是全球性的。第三，需要构造海洋/气候千年响应的正弦波信号，其可以用于与其他记录进行比较并作为预测模板。
