Impacts And Adaptation: Impacts on Hydrology
"Heavy Precipitation Processes in a Warmer Climate," C. Frei
(Atmospheric Sci., ETH, CH-8093, Zürich, Switz; e-mail:
email@example.com), C. Schär et al.,Geophys. Res. Lett.,
25(9), 1431-1434, May 1, 1998.
Experiments with a regional climate model carried out for Europe in the
fall season indicate a substantial shift towards more frequent events of
"Climate Change and Water Resources in Britain," N.W. Arnell
(Dept. Geog., Univ. Southampton, Highfield, Southampton SO17 1BJ, UK),Clim.
Change, 39(1), 83-110, May 1998.
Based on a review of simulations of changes in river flows, groundwater
recharge and river water quality, this paper explores implications for
water use and management. Increased pressures on water resources, expected
to result from climate change, will impact not only the reliability of
water supply, but also navigation, aquatic ecosystems, recreation and
"Evaporation and Potential Evapotranspiration in India Under
Conditions of Recent and Future Climate Change," N. Chattopadhyay, M.
Hulme (Clim. Res. Unit., Sch. Environ. Sci., Univ. E. Anglia, Norwich NR4
7TJ, UK),Agric. & Forest Meteor., 87(1), 55-73, Nov.
Analysis of data from various stations across India shows that both pan
evaporation and potential evapotranspiration have decreased during recent
years. Future warming projected by GCMs seems likely to lead to increased
potential evapotranspiration, with marked economic and environmental
"Climate Change Impacts on the Hydrologic Resources of Europe: A
Simplified Continental Scale Analysis," K.M. Strzepek (Civil,
Environ. & Architectural Eng., Univ. Colorado, Boulder CO 80309), D.N.
Yates,Clim. Change, 36(1-2), 79-92, May-June 1997.
Develops a simplified regional analysis based on GIS and annual climate
databases, and compares results to more complex analyses at the river
basin scale that use monthly water balance models. The simplified method
gives acceptable results, and is applied to Europe on the national and
"Changes in Daily Precipitation Under Enhanced Greenhouse Conditions,"
K.J. Hennessy (e-mail: firstname.lastname@example.org), J.M. Gregory (Hadley Ctr.,
Meteor. Off., London Rd., Bracknell, Berkshire RG12 2SY, UK), J.F.B.
Mitchell,Clim. Dynamics, 13(9), 667-680, 1997.
Examines the nature of global precipitation increases of about 10%
predicted by UK and Australian GCMs under doubled CO2. Both
models simulate fewer wet days in middle latitudes and more wet days in
high latitudes. The probability of heavy daily precipitation increases by
over 50% in many locations.
"Impacts of Global Climate Change in a Hydrologically Vulnerable
Region: Challenges to South African Hydrologists," R.E. Schulze
(Dept. Agric. Eng., Univ. Natal, Pietermaritzburg, P.B. X01, 3209
Scottsville, S. Africa),Progress in Phys. Geog., 21(1),
113-136, Mar. 1997.
Reviews projected perturbations to temperature, precipitation and
potential evaporation, and methods for simulating hydrological response to
climate change. Summarizes directions for research and presents two case
studies. Concludes by discussing whether water resources practitioners in
South Africa should respond to climate change.
