RISPropagation and the Vertical Structure of the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: The Madden?Julian oscillation (MJO) dominates tropical variability on time scales of 30?70 days. During the boreal winter?spring it is manifested as an eastward propagating disturbance, with a strong convective signature ...
An Observational Study of the Relationship between Excessively Strong Short Rains in Coastal East Africa and Indian Ocean SST
Publisher: American Meteorological Society
Abstract: Composites of SST, wind, rainfall, and humidity have been constructed for years of high rainfall during September, October, and November (SON) in equatorial and southern-central East Africa. These show that extreme East ...
Teleconnections of the Southern Oscillation in the Tropical Atlantic Sector in the OSU Coupled Upper Ocean–Atmosphere GCM
Publisher: American Meteorological Society
Abstract: The Oregon State University coupled upper ocean-atmosphere GCM has been shown to qualitatively simulate the Southern Oscillation. A composite analysis of the warm and cold events simulated in this 23-year integration has ...
Climatology and Interannual Variation of the East Asian Winter Monsoon: Results from the 1979–95 NCEP/NCAR Reanalysis
Publisher: American Meteorological Society
Abstract: This paper presents the climatology and interannual variation of the East Asian winter monsoon based on the 1979?95 National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis. In ...
MJO in the NCAR CAM2 with the Tiedtke Convective Scheme
Publisher: American Meteorological Society
Abstract: The boreal winter Madden?Julian oscillation (MJO) remains very weak and irregular in the National Center for Atmospheric Research (NCAR) Community Atmosphere Model version 2 (CAM2) as in its direct predecessor, the Community ...
Benchmarking Performance Changes in the Simulation of Extratropical Modes of Variability across CMIP Generations
Publisher: American Meteorological Society
Representation of Modes of Variability in Six U.S. Climate Models
Publisher: American Meteorological Society
Abstract: We compare the performance of several modes of variability across six U.S. climate modeling groups, with a focus on identifying robust improvements in recent models [including those participating in phase 6 of the Coupled ...
