RISLaterally Forced Equatorial Perturbations in a Linear Model. Part II: Mobile Forcing
Publisher: American Meteorological Society
Abstract: Impacts of atmospheric mean zonal flows on equatorial perturbations laterally forced by extratropical mobile sources in a linear model are examined. An analytical solution of the model with a constant mean zonal flow reveals ...
Large-Scale Variability of Atmospheric Deep Convection in Relation to Sea Surface Temperature in the Tropics
Publisher: American Meteorological Society
Abstract: Empirical relationships between tropical sea surface temperature (SST) and atmospheric deep convection are examined. Large-scale features of tropical deep convection are estimated from two independent satellite datasets: ...
Madden–Julian Oscillation: Bridging Weather and Climate
Publisher: American Meteorological Society
Abstract: n?Julian oscillation exerts broad influences on global weather and climate as its center of convection moves from the tropical Indian Ocean into the Pacific. Weather events under the influence of the MJO include precipitation, ...
On the Annual Cycle in Highest, Coldest Clouds in the Tropics
Publisher: American Meteorological Society
Abstract: High-resolution satellite observations are used to examine the annual cycle in mean areal coverage by highest, coldest clouds in the tropics. It is found that the mean fractional coverage by clouds with cloud-top temperatures ...
Intraseasonal Perturbations in Sea Surface Temperatures of the Equatorial Eastern Pacific and Their Association with the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: A particular pattern of intraseasonal perturbations in sea surface temperature (SST) is observed in the eastern Pacific Ocean following events of strong surface winds associated with the Madden?Julian oscillation (MJO). ...
Intraseasonal Variability of the Upper-Ocean Thermal Structure Observed at 0° and 165°E
Publisher: American Meteorological Society
Abstract: In response to perturbations in surface wind and energy fluxes associated with the atmospheric Madden?Julian oscillation (MJO), the thermal structure of the upper ocean (surface to 300 m) in the equatorial western Pacific ...
A Road Map to Success of International Field Campaigns in Atmospheric and Oceanic Sciences
Publisher: American Meteorological Society
Untitled
Publisher: American Meteorological Society
Abstract: AbstractExplanations for the barrier effect of the Indo-Pacific Maritime Continent (MC) on the MJO should satisfy two criteria. First, they should include specific features of the MC, namely, its intricate land?sea ...
A Case Study of the Mechanics of Extratropical Influence on the Initiation of the Madden–Julian Oscillation
Publisher: American Meteorological Society
Abstract: Mechanisms for extratropical influences on the initiation of the Madden?Julian oscillation (MJO) are investigated using numerical simulations and a global reanalysis product. Previous simulations by a tropical channel model ...
Westward-Propagating Synoptic-Scale Disturbances and the ITCZ
Publisher: American Meteorological Society
Abstract: In an attempt to understand the dynamics of the intertropical convergence zone (ITCZ), this study explores the extent to which the ITCZ is causally related to zonally propagating synoptic-scale disturbances. The ITCZ, ...
