Quantifying the processes of accelerated wintertime Tibetan Plateau warming: outside forcing versus local feedbacksSpringer Science and Business Media LLC - Tập 61 - Trang 3289-3307 - 2023
Mengchu Zhao, Xiu-Qun Yang, Lingfeng Tao
The Tibetan Plateau (TP) has experienced an accelerated wintertime warming in recent decades under global warming, but consensus on its causes has not yet been reached. This study quantifies the processes of the warming through analyzing surface temperature budget and surface energy balance. It is found that increased diabatic heating (73%) and warm advection (27%) by an anomalous anticyclone sout...... hiện toàn bộ
Snow-atmosphere coupling and its impact on temperature variability and extremes over North AmericaSpringer Science and Business Media LLC - - 2017
G. T. Diro, L. Sushama, O. Huziy
The impact of snow-atmosphere coupling on climate variability and extremes over North America is investigated using modeling experiments with the fifth generation Canadian Regional Climate Model (CRCM5). To this end, two CRCM5 simulations driven by ERA-Interim reanalysis for the 1981–2010 period are performed, where snow cover and depth are prescribed (uncoupled) in one simulation while they evolv...... hiện toàn bộ
Robustness, uncertainties, and emergent constraints in the radiative responses of stratocumulus cloud regimes to future warmingSpringer Science and Business Media LLC - Tập 46 - Trang 3025-3039 - 2015

Future responses of cloud regimes are analyzed for five CMIP5 models forced with observed SSTs and subject to a patterned SST perturbation. Correlations between cloud properties in the control climate and changes in the warmer climate are investigated for each of a set of cloud regimes defined using a clustering methodology. The only significant (negative) correlation found is in the in-regime net...... hiện toàn bộ
Cloud albedo feedback and the super greenhouse effect in a global coupled GCMSpringer Science and Business Media LLC - Tập 11 - Trang 399-411 - 1995
Gerald A. Meehl, Warren M. Washington
Two competing cloud-radiative feedbacks identified in previous studies i.e., cloud albedo feedback and the super greenhouse effect, are examined in a sensitivity study with a global coupled ocean-atmosphere general circulation model. Cloud albedo feedback is strengthened in a sensitivity experiment by lowering the sea-surface temperature (SST) threshold in the specified cloud albedo feedback schem...... hiện toàn bộ
Observed variability in the upper layers at the Equator, 90°E in the Indian Ocean during 2001–2008, 1: zonal currentsSpringer Science and Business Media LLC - Tập 49 - Trang 1077-1105 - 2016
R. R. Rao, T. Horii, Y. Masumoto, K. Mizuno
The observed variability of zonal currents (ZC) at the Equator, 90°E shows a strong seasonal cycle in the near-surface 40–350 m water column with periodic east–west reversals most pronounced at semiannual frequency. Superposed on this, a strong intraseasonal variability of 30–90 day periodicity is also prominently seen in the near-surface layer (40–80 m) almost throughout the year with the only e...... hiện toàn bộ
