open access: yes, 2016
热带季节内振荡(在大气中以Madden-JulianOscillation为主,以下简称MJO),是全球季节内尺度预报的最主要信号来源,在天气气候系统的预报中起着非常重要的作用。作为目前发现的全球最强的季节内准周期信号,国内外普遍认为MJO的预报是联系数值天气预报和季节预报的桥梁,能够填补中期预报与短期气候预测之间的延伸期预报时段的“缝隙”。自20世纪70年代Madden和Julian提出以来,MJO现已在国际上获得了广泛关注,其机理研究和预报开展已经成为了全球气候研究的热门方向之一 ...

open access: yes, 2016
在1990年统一之初,也门曾被国际舆论公认为和平统一的典范。然而,时过境迁,当今的也门却被公认为失败国家的典型。从和平统一的模范生到失败国家的注脚,也门国家命运的大起大落令人唏嘘不已,究竟什么原因导致了也门国家整合的失败是一个颇值得深入探究的学术问题。本文从精英较量的视角出发对也门国家整合中的重要组成部分—也门南北整合问题做了深入探讨,指出该视角或许是探讨也门南北整合问题的最佳解释路径。本文以拉克曼的精英理论为基础,以也门案例为背景构建精英较量的分析框架,从而对也门统一以来的前十二年—即1990 ...
