RISThe Moist Static Energy Budget of a Composite Tropical Intraseasonal Oscillation in a Climate Model
Publisher: American Meteorological Society
Abstract: The intraseasonal moist static energy (MSE) budget is analyzed in a climate model that produces realistic eastward-propagating tropical intraseasonal wind and precipitation variability. Consistent with the recharge?discharge ...
An Intraseasonal Oscillation Composite Life Cycle in the NCAR CCM3.6 with Modified Convection
Publisher: American Meteorological Society
Abstract: The NCAR CCM3.6 with microphysics of clouds with relaxed Arakawa?Schubert convection produces an intraseasonal oscillation that is highly dependent on lower-tropospheric moistening by surface convergence. Model intraseasonal ...
Dr. Yanai’s Contributions to the Discovery and Science of the MJO
Publisher: American Meteorological Society
Abstract: his chapter reviews Professor Michio Yanai?s contributions to the discovery and science of the Madden?Julian oscillation (MJO). Professor Yanai?s work on equatorial waves played an inspirational role in the MJO discovery ...
On the Convective Coupling and Moisture Organization of East Pacific Easterly Waves
Publisher: American Meteorological Society
Abstract: rocesses associated with the local amplification of easterly waves (EWs) in the east Pacific warm pool are explored. Developing EWs favor convection in the southwest and northeast quadrants of the disturbance. In nascent ...
The Madden–Julian Oscillation, Barotropic Dynamics, and North Pacific Tropical Cyclone Formation. Part I: Observations
Publisher: American Meteorological Society
Abstract: Low-level barotropic dynamics may help to explain the modulation of eastern and western North Pacific tropical cyclones by the Madden?Julian oscillation (MJO) during Northern Hemisphere summer. The MJO is characterized by ...
The Influence of the MJO on Upstream Precursors to African Easterly Waves
Publisher: American Meteorological Society
Abstract: he Madden?Julian oscillation (MJO) produces alternating periods of increased and reduced precipitation and African easterly wave (AEW) activity in West Africa. This study documents the influence of the MJO on the West ...
The Intraseasonal Variability of African Easterly Wave Energetics
Publisher: American Meteorological Society
Abstract: frican easterly waves (AEWs) and associated perturbation kinetic energy (PKE) exhibit significant intraseasonal variability in tropical North Africa during boreal summer. Consistent with East Africa (e.g., east of Lake ...
Satellite and Buoy Observations of Boreal Summer Intraseasonal Variability in the Tropical Northeast Pacific
Publisher: American Meteorological Society
Abstract: Tropical intraseasonal variability in the eastern North Pacific during June?September of 2000?03 is analyzed using satellite and buoy observations. Quick Scatterometer ocean vector winds and the Tropical Rainfall Measuring ...
Energetics of East Pacific Easterly Waves during Intraseasonal Events
Publisher: American Meteorological Society
Abstract: he background atmospheric state of the east Pacific warm pool in which easterly waves develop varies dramatically on intraseasonal time scales. East Pacific intraseasonal variability is well known to modulate local convective ...
