风场是表征大气环流和动力学结构的直接参数，能够通过波流相互作用影响大气波动的传播，通过中性成分与带电粒子之间的碰撞而影响电离层等。然而，目前对全球中高层大气风场的探测还面临巨大挑战，地基和卫星的风场探测还局限于某些高度范围，无法得到平流层至低热层整个高度范围的完整风场。因此，中国科学院国家空间科学中心（以下简称“空间中心”）太阳活动与空间天气重点实验室科研人员结合TIME/SABER卫星和子午工程...
树轮稳定氧同位素（δ18OTR）是研究过去气候变化的重要代用指标。但是，δ18OTR记录的气候和环流信号非常复杂，合理解读这些信号的来源是基于δ18OTR重建过去气候的前提。
本文引入3阶主张量分析方法对1993~2008年赤道太平洋地区卫星测高数据进行解析,前两个主张量可有效表征海面变化的经、纬向耦合特征,重构与对比了该时段内6次ENSO事件海面变化的经、纬向演化的空间构型与耦合作用过程.结果表明:海面的经向变化可表征ENSO强度变化,纬向变化表现为受ENSO影响的年周期波动;经、纬向张量的时间系数与MEI以及EMI指数间多尺度分析表明,两者均受El Ni&ntild...

The presence of nonlinear terms in the governing equations of a dynamical system usually leads to the loss of predictability, e.g. in numerical weather prediction. However, for the El Niño-Sout...
