The El Nino-Southern Oscillation (ENSO) is the best example of a climate variation on earth that is produced by an internal feedback in the climate system. With a quasi-periodic oscillation of 2-6 years, it is also a climate variation that has important human impacts. The history of ENSO is well documented for about the last 50 to 100 years from direct observation and the last 500 years from historical and other written anecdotal evidence. It is important to understand how this internal feedback may affect future climate change. In order to accomplish this, it will be necessary to extend the record of ENSO climate change back in time to understand how the system responds to varying climatic states. This proposal will result in a record of ENSO dating back to about 622 AD. It will be based on the record of Nile River discharge measured at Cairo, Egypt. This research is important because it will provide direct observation of natural climate variations on annual and decadal time scales. The results will be most useful for understanding how the earth responds to short-term internal perturbations and how these responses might be affected by climate change.

厄尔尼诺-南方涛动（ENSO）是最好的 地球上的气候变化是由一个 气候系统的内部反馈。 具有准周期性 振荡2-6年，它也是一种气候变化， 重要的人类影响。 ENSO的历史是有据可查的 在过去的50到100年里， 过去500年的历史和其他书面轶事 证据 重要的是要了解这种内部 反馈可能会影响未来的气候变化。 为了 要做到这一点，有必要延长记录， ENSO气候变化及时了解系统如何 对不同的气候状态作出反应。 这一提议将导致 在公元622年的ENSO记录中。 将 根据尼罗河流量的记录， 埃及开罗。这项研究很重要，因为它将提供 直接观测自然气候的年变化， 年代际时间尺度 结果将是最有用的， 了解地球如何应对短期的内部 扰动以及这些响应如何受到 气候变化
