  • 简介:东方亚洲冬季季风(EAWM)的可变性能被划分成ENSO相关的部分(EAWMEN)和ENSO无关的部分(EAWMres)。在腐烂的关系ENSO上演的ENSO东方亚洲夏天季风(EASM)上的EAWMres的影响在现在的学习被调查。完成这,ENSO基于EAWMres被划分成四个组:(1)弱EAWMres-ElNi?o(WEAWMres在);(2)强壮的EAWMres-ElNi?o(SEAWMres-在);(3)弱EAWMres-LaNi?一(WEAWMres行);(4)强壮的EAWMres-LaNi?一(SEAWMres行)。合成结果证明EAWMres可以为WEAWMres在和SEAWMres行在东亚上提高大气的回答到ENSO。相应低级逆旋风(气旋)在西方的诺思太平洋(WNP)上的异例把Ni与El联系了?o(LaNi?一)趋于强壮。重要地,这个特征可以坚持直到下列夏天,引起在为WEAWMres在案例的北中国并且在为SEAWMres行案例的西南的中国的丰富的降雨。为SEAWMres在和WEAWMres行组,相反,EAWMres趋于削弱与ElNi联系的大气的发行量异例?o或LaNi?一。在这些,情况,异常WNP反气旋或气旋趋于被减少并且限制了降低纬度,它为WEAWMres行为SEAWMres在并且在西南的中国在北中国导致缺乏的夏天降雨。进一步的学习建议异常EAWMres可以在热带以外的海表面温度异例上有效果,它坚持直到随后的夏天并且可以防碍ENSO的影响。

  • 简介:AbstractMode of delivery in twin gestation has been a matter of debate for decades. In 2013, the only randomized controlled trial concerning mode of delivery in twin gestations was published, answering some of the most pressing questions in this matter. The Twin Birth Study randomized patients carrying dichorionic-diamniotic or monochorionic-diamniotic twins, with the first twin in cephalic presentation, between 32 and 39 weeks of gestation, to planned vaginal vs. planned cesarean delivery, and found no significant differences in perinatal or maternal outcomes. These clinical findings greatly benefit our clinical practice, but there lacks related study investigating how the practices have changed. In this review, we searched PubMed from 1980 through January 2021 using combinations of the following terms: twin, delivery, vaginal delivery, and cesarean section. We will try to address the known literature before and after the publication of the Twin Birth Study in western countries and compare that to what has been practiced in China.
