研究评估大西洋强飓风变化
大西洋 强飓风 热带气旋
2021/7/27
大西洋最强飓风（强飓风）近期的增加，可能不属于百年尺度上的变化，而是从20世纪60年代至80年代最低活动水平的回升。然而，7月13日刊登于《自然—通讯》的这一研究结果，并不意味着气候变化对热带气旋的频次和强度没有任何影响。研究人员认为，气候变率以及气溶胶引起的飓风减少，可能掩盖了温室气体导致的升温在百年尺度上对北大西洋强飓风发生频次的贡献。

尧中华等-SA等：揭示木星极区软X-射线极光成因之谜（图）
木星 X-射线 极光辐射
2021/7/21
40年前，天文学家利用太空望远镜发现了木星的X-射线极光辐射，并把它看作认识宇宙空间X-射线辐射机制的重要参考。之后的持续观测让我们对木星X-射线极光特征有了系统的认识，但对它的产生机理却一直没有解释。随着国际上木星探测飞船的实施，我们首次直接“看到”了木星X-射线辐射时的空间过程，这为解释木星X-射线极光成因提供了必要条件。

喀斯特地貌 贵州 可持续发展
2021/7/22
贵州作为典型喀斯特地区，地处西南喀斯特地区中心地带，具有地理、地质、社会、经济系统的特殊性。要想利用好喀斯特生态环境，就要因地制宜，适应性进行生态系统调控，更好地、可持续地利用好我们一系列生物资源、旅游资源以及其他资源是我们贵州将来必须走的生态文明建设道路。
NC：深源气体释放视角下的青藏高原东南部生长动力学过程（图）
青藏高原 气体释放 生长动力学
2021/7/22
天津大学地球系统科学学院、中国科学院地质与地球物理研究所、美国伍兹霍尔海洋研究所以及日本东京大学大气海洋研究所等国内外科研机构的研究团队，聚焦青藏高原东南部的主要活动断裂带和第四纪火山区（图1），利用温泉气体的化学成分、He-C-N同位素组成以及定量计算模型，有效区分并厘清了温泉气体中幔源和壳源气体的贡献比例及其空间变化特征，建立了印度-亚洲大陆汇聚背景下深源气体释放与区域应力分布之间的耦合关系。
