  2. 1. Atmospheric dynamics and the hydrologic cycle in warm climates

    Author : Henrik Carlson; Rodrigo Caballero; Johan Nilsson; Jonathan L. Mitchell; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; superrotation; early Eocene; warm climates; Madden-Julian Oscillation; the hydrologic cycle; vegetation sensitivity; large-scale circulation; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Past warm climates represent one extreme of Earth's known climate states. Here, we study warm climates in both idealized simulations and full-complexity general circulation model (GCM) simulations of the early Eocene epoch, approximately 50 million years ago. READ MORE

  4. 2. The Precipitationshed : Concepts, Methods, and Applications

    Author : Patrick W. Keys; Line Gordon; Deliang Chen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water; atmosphere; precipitationshed; moisture recycling; variability; ecosystem services; social-ecological systems; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Human societies are reliant on the functioning of the hydrologic cycle. The atmospheric branch of this cycle, often referred to as moisture recycling in the context of land-to-land exchange, refers to water evaporating, traveling through the atmosphere, and falling out as precipitation.

  5. 3. Changes of evapotranspiration and water cycle in China during the past decades

    Author : Ge Gao; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Potential evapotranspiration; Actual evapotranspiration; Spatial and temporal characteristic; Trend; Controlling factors; Water cycle; Thornthwaite water balance; China;

    Abstract : Evapotranspiration is the second largest quantity in the water cycle and an important indicator for climate changes. Accurate estimations and better understanding of evapotranspiration are required in hydrologic studies and water resources modelling under stationary and changing climate conditions. READ MORE

  6. 4. The role of the hydrological cycle in forest ecosystems : flow path, nutrient cycling and water-carbon interaction

    Author : Yanzi Yan; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; flow path; DOC concentration; groundwater; photosynthesis; Amazon rainforest; catchment geomorphology;

    Abstract : Forest ecosystems, covering over a third of land on the Earth, play a significant role in the global hydrological cycle, and influence soil erosion and climate change. However, the distribution, movements, quality of water, and hydrological processes in forested ecosystems are not well understood yet. READ MORE

  7. 5. Seasonality and variability of stratospheric water vapour

    Author : Tongmei Wang; Abdel Hannachi; Qiong Zhang; Alexey Karpechko; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stratospheric water vapour; seasonality; variability; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Stratospheric water vapour (SWV) plays a critical role in the climate system by modulating the radiation budget and influencing the stratospheric chemistry. Studying changes of SWV on global scale is helpful for our understanding of climate change. READ MORE
