CO2 climate sensitivity and snow-sea-ice albedo parameterization in an atmospheric GCM coupled to a mixed-layer ocean modelClimatic Change - Tập 16 - Trang 283-306 - 1990
Gerald A. Meehl, Warren M. Washington
The snow-sea-ice albedo parameterization in an atmospheric general circulation model (GCM), coupled to a simple mixed-layer ocean and run with an annual cycle of solar forcing, is altered from a version of the same model described by Washington and Meehl (1984). The model with the revised formulation is run to equilibrium for 1 × CO2 and 2 × CO2 experiments. The 1 ×CO2 (control) simulation produce...... hiện toàn bộ
Vulnerability and risk: climate change and water supply from California’s Central Valley water systemClimatic Change - Tập 161 - Trang 177-199 - 2020
Patrick Ray, Sungwook Wi, Andrew Schwarz, Matthew Correa, Minxue He, Casey Brown
Water allocation institutions globally must operate within legal and political contexts established by precedent and codified in operating rules, even as they flex and adjust to climate change. California’s Central Valley Water System (CVS) is a prime example. Recent global, national, regional, and local climate change assessments have highlighted climate-change-driven impacts on the CVS; however,...... hiện toàn bộ
A new scenario framework for climate change research: the concept of shared climate policy assumptionsClimatic Change - Tập 122 - Trang 401-414 - 2014
Elmar Kriegler, Jae Edmonds, Stéphane Hallegatte, Kristie L. Ebi, Tom Kram, Keywan Riahi, Harald Winkler, Detlef P. van Vuuren
The new scenario framework facilitates the coupling of multiple socioeconomic reference pathways with climate model products using the representative concentration pathways. This will allow for improved assessment of climate impacts, adaptation and mitigation. Assumptions about climate policy play a major role in linking socioeconomic futures with forcing and climate outcomes. The paper presents t...... hiện toàn bộ
Variations of East African Climate during the Past Two CenturiesClimatic Change - Tập 50 - Trang 209-217 - 2001
Stefan Hastenrath
The evidence on the climatic history of East Africa over the past two centuries comprises historical accounts of lake levels, observations and analyses of glacier variations, wind and current observations in the Indian Ocean, as well as raingauge measurements. East Africa experiences its rainy seasons in boreal spring and autumn, centered around April–May and October–November; the spring rains bei...... hiện toàn bộ
Direct radiative effects of tropospheric aerosols on changes of global surface soil moistureClimatic Change - Tập 136 - Trang 175-187 - 2016
Shaoqing Liu, Min Chen, Qianlai Zhuang
A coupled modeling framework including a terrestrial ecosystem model and an atmospheric radiative transfer model is used to evaluate the aerosols’ direct radiative effects on the surface soil moisture in global terrestrial ecosystems during 2003–2010. We conduct two sets of model runs with and without aerosols in a hindcast mode. Comparison analysis indicates that the simulated soil moisture is co...... hiện toàn bộ
Spatially explicit modelling of the impact of climate changes on pasture production in the North Island,New ZealandClimatic Change - Tập 84 - Trang 203-216 - 2007
Baisen Zhang, Ian Valentine, Peter D. Kemp
To assess the potential impact of climate changes on pasture production in the North Island, New Zealand, eight climate scenarios of increased temperature and increased (or decreased) rainfall were investigated by integrating a polynomial regression model for pasture production with a Geographic Information System (GIS). The results indicated that the climate change scenarios assuming an increase ...... hiện toàn bộ
