ESR：系统阐述青藏高原地气之间水热通量交换的时空变化规律（图）
青藏高原地气 水热通量交换 时空变化规律
2023/1/16
青藏高原巨大的抬升地形可接收大量太阳辐射，形成独特的热力干扰源，对区域大气循环和亚洲季风进程产生重要影响。青藏高原热力作用主要通过地表和大气之间能量和水分的交换过程实现。然而，青藏高原极端严酷的自然环境条件和复杂多样的下垫面状况，使得青藏高原地气之间水热通量交换的时空变化规律存在诸多不确定性。

青藏科考 第二次 系统阐述 亚洲水塔失衡
2023/1/16
以青藏高原为核心的第三极，固态水储量仅次于南北极。作为地球上近20亿人赖以生存的十多条大江大河和数以千计的大小湖泊的源头，它也被称为“亚洲水塔”（图1）。第二次青藏科考在《自然综述：地球与环境》发表最新研究成果，系统阐述亚洲水塔失衡问题。
HESS：水热通量相位差影响青藏高原湖泊水位季节变化（图）
水热通量相位差 青藏高原 湖泊水位 季节变化
2023/1/17
青藏高原湖泊众多，是“亚洲水塔”的重要组成部分。受气候变化影响，青藏高原内陆区大多数湖泊自90年代末出现显著扩张，但高原南部湖泊出现一定的萎缩。湖泊变化对区域生态环境产生了一定影响。由于地处偏远、气候环境恶劣，青藏高原内陆区系统的湖泊水文气象观测资料较少，限制了人们对湖泊水文过程的认识。在多年连续观测的基础上，中科院青藏高原研究所环境变化与多圈层过程团队类延斌副研究员与其合作者，通过能量平衡方法(...
