Dryas

基本解释

Before the Younger Dryas, the world had been warming up as the last ice age came to an end.
在新仙女木期之前。由于冰河时期的结束，地球正在逐渐变暖。
Younger Dryas event (YD) is an abrupt cooling event in the warming period, a nearest and intense cooling event in the geologic record.
在目前持续升温的情况下,研究YD事件的全球变化和区域响应对了解未来气候变化及其对自然环境和对人类社会的影响有着非常重要的意义。
But as for the cause of the Younger Dryas, the eyes of science were, until now, directed not up at the sky, but down into the ocean.
但在今天，以科学的眼光来看，新仙女木期的真正原因，并不是直接来自于天上，而是来自于海洋之中。
The variations of organic carbon, organic nitrogen, magnetic susceptibility and geochemi-cal element contents in core sediments all well coincide with the climatic change in the Dryas period.
岩心沉积物的有机碳、有机氮和磁化率以及化学元素含量的变化,都与仙女本期气候变化具有十分吻合的变化态势。
Palaeontologists have a name for the sudden cooling of the climate of the northern hemisphere that started right then and lasted for over a thousand years.They call it the Younger Dryas.
古生物学家将从那时开始并持续了超过一千年的北半球的气候称为新仙女木期。
