Does the Lack of Coupling in SST-Forced Atmosphere-Only Models Limit Their Usefulness for Climate Change Studies?
Publisher: American Meteorological Society
Abstract: tmospheric general circulation models (AGCMs) are often considered inadequate for studying natural climate variability because of their lack of coupling with an underlying ocean. This lack of two-way air?sea coupling results ...
Anthropogenic Weakening of the Tropical Circulation: The Relative Roles of Direct CO2 Forcing and Sea Surface Temperature Change
Publisher: American Meteorological Society
Abstract: here is a lack of consensus on the physical mechanisms that drive the anthropogenic weakening of tropical circulation. This study investigates the relative roles of direct CO2 forcing, mean SST warming, and the pattern of ...
Atmospheric and Oceanic Origins of Tropical Precipitation Variability
Publisher: American Meteorological Society
Abstract: he intrinsic atmospheric and ocean-induced tropical precipitation variability is studied using millennial control simulations with various degrees of ocean coupling. A comparison between the coupled simulation and the ...
Transient Climate Sensitivity Depends on Base Climate Ocean Circulation
Publisher: American Meteorological Society
Abstract: here is large uncertainty in the simulation of transient climate sensitivity. This study aims to understand how such uncertainty is related to the simulation of the base climate by comparing two simulations with the same ...
On the Climatology and Trend of the Atmospheric Heat Source over the Tibetan Plateau: An Experiments-Supported Revisit
Publisher: American Meteorological Society
Abstract: Atmospheric heating over the Tibetan Plateau (TP) enhances the Asian summer monsoon. This study presents a state-of-the-art estimate of the heating components and their total over the TP, with the aid of high-accuracy ...
Comparison of Downscaled Precipitation Data over a Mountainous Watershed: A Case Study in the Heihe River Basin
Publisher: American Meteorological Society
Abstract: evelopment of an accurate precipitation dataset is of primary importance for regional hydrological process studies and water resources management. Here, four regional precipitation products are evaluated for the Heihe River ...
Why Has the Inner Tibetan Plateau Become Wetter since the Mid-1990s?
Publisher: American Meteorological Society
Abstract: The Inner Tibetan Plateau (ITP; also called the Qiangtang Plateau) appears to have experienced an overall wetting in summer (June, July, and August) since the mid-1990s, which has caused the rapid expansion of thousands ...
