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(...
VLA and XMM-Newton Observations of the SNR W41/TeV Gamma-Ray Source HESS J1834–087
W41 HESS
2014/12/23
The recently discovered extended TeV source HESS J1834-087 is associated with both a diffuse X-ray enhancement and a molecular cloud, projected at the center of an old radio supernova remnant, G23.3-0...
CANGAROO-III observation of TeV gamma rays from the unidentified gamma-ray source HESS J1614-518
CANGAROO-III observation unidentified gamma-ray source HESS J1614-518
2011/10/12
We report the detection, with the CANGAROO-III imaging atmospheric Cherenkov telescope array, of a very high energy gamma-ray signal from the unidentified gamma-ray source HESS J1614-518, which was di...
HESS Opinions: Hydrologic predictions in a changing environment: behavioral modeling
Hydrologic predictions changing environment behavioral modeling
2011/3/15
Most hydrological models are valid at most only in a few places and cannot be reasonably transferred to other places or to far distant time periods. Transfer in space is difficult because the models a...
Discovery and follow-up studies of the extended, off-plane, VHE gamma-ray source HESS J1507-622
follow-up studies off-plane VHE gamma-ray source HESS J1507-622
2011/1/10
Context: The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV-100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles found in astrophysica...
According to the traditional notion of randomness and uncertainty, natural phenomena are separated into two mutually exclusive components, random (or stochastic) and deterministic. Within this dichoto...
HESS Opinions On the use of laboratory experimentation:“Hydrologists,bring out shovels and garden hoses and hit the dirt”
HESS Opinions laboratory experimentation Hydrologists shovels garden hoses
2010/3/5
From an outsider's perspective, hydrology combines field work with modelling, but mostly ignores the potential for gaining understanding and conceiving new hypotheses from controlled laboratory experi...

catchments hydrological models
2009/10/10
As all hydrological models are intrinsically limited hypotheses on the behaviour of catchments, models – which attempt to represent real-world behaviour – will always remain imperfect. To make progre...

HESS Opinions “Urgent water challenges are not sufficiently researched”
Urgent water challenges sufficiently researched HESS Opinions
2009/7/22
In this opinion paper we submit that water experts conduct comparatively little research on the more urgent challenges facing the global community. Five specific biases are identified. First, researc...
