The Effect of Irrigation on Regional Temperatures: A Spatial and Temporal Analysis of Trends in California, 1934–2002
Publisher: American Meteorological Society
Abstract: The response of air temperatures to widespread irrigation may represent an important component of past and/or future regional climate changes. The quantitative impact of irrigation on daily minimum and maximum temperatures ...
A Wintertime Arctic Oscillation Signature on Early-Season Indian Ocean Monsoon Intensity
Publisher: American Meteorological Society
Abstract: The Indian Ocean monsoon (IOM) exhibits considerable year-to-year variations that have previously been attributed to a number of forcing mechanisms including the El Niño?Southern Oscillation (ENSO) and Eurasian snow cover ...
The Role of Irrigation Expansion in Past and Future Temperature Trends
Publisher: American Meteorological Society
Abstract: Expansion of irrigated land can cause local cooling of daytime temperatures by up to several degrees Celsius. Here the authors compare the expected cooling associated with rates of irrigation expansion in developing countries ...
Hot Desert Albedo and Climate Change: Mid-Holocene Monsoon in North Africa
Publisher: American Meteorological Society
Abstract: Many models in the framework of the Paleoclimate Modelling Intercomparison Project have undertaken simulations of the mid-Holocene (6 kyr ago) climate change. Analysis of the results have mainly focused on the North African ...
Comments on “Methodology and Results of Calculating Central California Surface Temperature Trends: Evidence of Human-Induced Climate Change?”
Publisher: American Meteorological Society
Observed and Projected Changes to the Precipitation Annual Cycle
Publisher: American Meteorological Society
Abstract: AbstractAnthropogenic climate change is predicted to cause spatial and temporal shifts in precipitation patterns. These may be apparent in changes to the annual cycle of zonal mean precipitation P. Trends in the amplitude ...
Benchmarking Performance Changes in the Simulation of Extratropical Modes of Variability across CMIP Generations
Publisher: American Meteorological Society
External Influences on Modeled and Observed Cloud Trends
Publisher: American Meteorological Society
Abstract: nderstanding the cloud response to external forcing is a major challenge for climate science. This crucial goal is complicated by intermodel differences in simulating present and future cloud cover and by observational ...
Relative Contributions of Mean-State Shifts and ENSO-Driven Variability to Precipitation Changes in a Warming Climate
Publisher: American Meteorological Society
Abstract: l Niño?Southern Oscillation (ENSO) is an important driver of regional hydroclimate variability through far-reaching teleconnections. This study uses simulations performed with coupled general circulation models (CGCMs) to ...
Competing Influences of Anthropogenic Warming, ENSO, and Plant Physiology on Future Terrestrial Aridity
Publisher: American Meteorological Society
Abstract: AbstractThe 2011?16 California drought illustrates that drought-prone areas do not always experience relief once a favorable phase of El Niño?Southern Oscillation (ENSO) returns. In the twenty-first century, such an ...
