We develop, evaluate, and apply "SynthETC," a statistical-stochastic model of winter extra-tropical cyclones (ETCs) over eastern North America. SynthETC simulates the life cycle of ETCs from formation to termination, and it can be used to e...
The relationship between boundary layer stability and cloud cover in the post-cold frontal region [0.03%]
后冷锋区边界层稳定性与云量关系研究

Catherine M Naud
Using NASA-Aqua MODIS and AIRS data, the relationship between low-level cloud cover (cloud top below the 700 hPa level) and boundary layer stability is explored in post-cold frontal conditions. A linear relationship is found between seasona...
Competing influences of anthropogenic warming, ENSO, and plant physiology on future terrestrial aridity [0.03%]
人为增温、ENSO和植物生理因素对未来陆地干旱竞争性影响

Céline Bonfils et al.
The 2011-2016 Californian drought illustrates that drought-prone areas do not always experience relief once a favorable phase of El Niño-Southern Oscillation (ENSO) returns. In the 21st century, such an expectation is unrealistic in region...
The 2015/2016 El Niño Event in Context of the MERRA-2 Reanalysis: A Comparison of the Tropical Pacific with 1982/1983 and 1997/1998 [0.03%]
基于MERRA-2再分析的2015/2016年厄尔尼诺事件与1982/1983年和1997/1998年的比较：热带太平洋地区的对比研究
Young-Kwon Lim,Robin M Kovach,Steven Pawson et al.
Young-Kwon Lim et al.
The 2015/2016 El Niño is analyzed using atmospheric/oceanic analysis produced using the Goddard Earth Observing System (GEOS) data assimilation systems. As well as describing the structure of the event, a theme of the work is to compare an...
Large-scale Controls on Atlantic Tropical Cyclone Activity on Seasonal Time Scales [0.03%]
影响大西洋热带气旋活动的大尺度因子在季节时间尺度上的作用
Young-Kwon Lim,Siegfried D Schubert,Oreste Reale et al.
Young-Kwon Lim et al.
Interannual variations in seasonal tropical cyclone (TC) activity (e.g., genesis frequency and location, track pattern, and landfall) over the Atlantic are explored by employing observationally-constrained simulations with the NASA Goddard ...

A significant disruption of the Quasi-Biennial Oscillation (QBO) occurred during the Northern Hemisphere (NH) winter of 2015-16. Since the QBO is the major wind variability source in the tropical lower stratosphere and influences the rate o...
Evaluation of Extratropical Cyclone Precipitation in the North Atlantic Basin: An analysis of ERA-Interim, WRF, and two CMIP5 models [0.03%]
北大西洋地区温带气旋降水的评估研究——基于ERA-Interim、WRF及两个CMIP5模式的分析
James F Booth,Catherine M Naud,Jeff Willison
James F Booth
The representation of extratropical cyclones (ETCs) precipitation in general circulation models (GCMs) and a weather research and forecasting (WRF) model is analyzed. This work considers the link between ETC precipitation and dynamical stre...
The MERRA-2 Aerosol Reanalysis, 1980 - onward, Part I: System Description and Data Assimilation Evaluation [0.03%]
MERRA-2气溶胶再分析（1980年至今）第一部分：系统描述及数据同化检验

Lawrence Coy et al.
The structure, dynamics, and ozone signal of the Quasi-Biennial Oscillation produced by the 35-year NASA MERRA-2 (Modern-Era Retrospective Analysis for Research and Applications) reanalysis are examined based on monthly mean output. Along w...
