The coupled ocean–atmosphere hydrologic cycle

Seasonal Cycle and Interannual Variability in the Amazon Hydrologic Cycle

An analysis of the Amazon basin hydrologic cycle has been carried out using the NASA/GEOS1 atmospheric reanalysis, observed rainfall of Xie and Arkin, and historical Amazon river discharge. Over a seasonal cycle, the precipitation is found to vary by 5 mm day 1, the runo by 2 mm day 1 while the evaporation largely remains constant. On interannual time scales, the hydrologic variability both in ...

New Cloud-radiation and Hydrologic Cycle Parameterizations

The availability of new observational data from field programs has yielded new insights into the relationships between cloud microphysics and cloud radiative effects. Tests in single-column mode, carried out in the maritime tropics, in polar regions, and in mid-latitudes, have shown that parameterizations based on these new results can significantly reduce typical model biases in cloud-modulate...

Literature Review: Aerosols and Hydrologic cycle

Tiny airborn particles including those released by human activities and the secondary organic aerosols have potential impacts on the hydrologic cycle. This review briefly introduces the aerosols formation, potential feedback between the aerosols and hydrologic cycle. Recent progress in aerosols, cloud and precipitation is described. The current status using model tools to investigate the intera...

Simulating the hydrologic cycle in coal mining subsidence areas with a distributed hydrologic model

Large-scale ground subsidence caused by coal mining and subsequent water-filling leads to serious environmental problems and economic losses, especially in plains with a high phreatic water level. Clarifying the hydrologic cycle in subsidence areas has important practical value for environmental remediation, and provides a scientific basis for water resource development and utilisation of the s...
