RISImprovement of a Cloud Microphysics Scheme for a Global Nonhydrostatic Model Using TRMM and a Satellite Simulator
Publisher: American Meteorological Society
Abstract: he cloud and precipitation simulated by a global nonhydrostatic model with a 3.5-km horizontal resolution, the Nonhydrostatic Icosahedral Atmospheric Model (NICAM), are evaluated using the Tropical Rainfall Measuring Mission ...
Moistening Processes before the Convective Initiation of Madden–Julian Oscillation Events during the CINDY2011/DYNAMO Period
Publisher: American Meteorological Society
Abstract: onvective initiation processes in the Madden?Julian oscillation (MJO) events that occurred during the Cooperative Indian Ocean Experiment on Intraseasonal Variability in the Year 2011 (CINDY2011)/Dynamics of the Madden?Julian ...
Impact of Rossby and Kelvin Wave Components on MJO Eastward Propagation
Publisher: American Meteorological Society
Abstract: AbstractThere are contrasting views concerning the impact of Rossby wave component of MJO flow on its eastward propagation. One view (called ?drag effect?) argues that because Rossby waves propagate westward, a stronger ...
Interaction between the MJO and High-Frequency Waves over the Maritime Continent in Boreal Winter
Publisher: American Meteorological Society
Abstract: AbstractThe two-way interaction between Madden?Julian oscillation (MJO) and higher-frequency waves (HFW) over the Maritime Continent (MC) during boreal winter of 1984?2005 is investigated. It is noted from observational ...
Multiscale Organization of Convection Simulated with Explicit Cloud Processes on an Aquaplanet
Publisher: American Meteorological Society
Abstract: This study investigated the multiscale organization of tropical convection on an aquaplanet in a model experiment with a horizontal mesh size of 3.5 km (for a 10-day simulation) and 7 km (for a 40-day simulation). The ...
Genesis of Super Cyclone Pam (2015): Modulation of Low-Frequency Large-Scale Circulations and the Madden-Julian Oscillation by Sea Surface Temperature Anomalies
Publisher: American Meteorological Society
Abstract: uper Cyclone Pam (2015) formed in the central tropical Pacific under conditions that included El Niño Modoki and the passage of a convectively-enhanced phase of the Madden?Julian Oscillation (MJO) in the western Pacific. ...
Convectively Coupled Equatorial Waves Simulated on an Aquaplanet in a Global Nonhydrostatic Experiment
Publisher: American Meteorological Society
Abstract: Large-scale tropical convective disturbances simulated in a 7-km-mesh aquaplanet experiment are investigated. A 40-day simulation was executed using the Nonhydrostatic Icosahedral Atmospheric Model (NICAM). Two scales of ...
MJO Initiation Processes over the Tropical Indian Ocean during DYNAMO/CINDY2011
Publisher: American Meteorological Society
Abstract: multination joint field campaign called the Dynamics of MJO/Cooperative Indian Ocean Experiment on Intraseasonal Variability in Year 2011 (DYNAMO/CINDY2011) took place in the equatorial Indian Ocean (IO) in late 2011. ...
Response of Tropical Cyclone Activity and Structure to Global Warming in a High-Resolution Global Nonhydrostatic Model
Publisher: American Meteorological Society
Abstract: AbstractFuture changes in tropical cyclone (TC) activity and structure are investigated using the outputs of a 14-km mesh climate simulation. A set of 30-yr simulations was performed under present-day and warmer climate ...
Convective Momentum Transport by Rainbands within a Madden–Julian Oscillation in a Global Nonhydrostatic Model with Explicit Deep Convective Processes. Part I: Methodology and General Results
Publisher: American Meteorological Society
Abstract: he convective momentum transport (CMT) properties of 13 215 rainbands within a Madden?Julian oscillation (MJO) event simulated by a global nonhydrostatic model are examined. CMT vectors, which represent horizontal accelerations ...
