RISVariations of the Moist Static Energy Budget of the Tropical Indian Ocean Atmospheric Boundary Layer
Publisher: American Meteorological Society
Abstract: AbstractThe atmospheric circulation depends on poorly understood interactions between the tropical atmospheric boundary layer (BL) and convection. The surface moist static energy (MSE) source (130 W m?2, of which 120 W m?2 ...
Fast Floating Temperature Sensor Measures SST, Not Wet-Bulb Temperature

The Tropical Eastern Pacific Seasonal Cycle: Assessment of Errors and Mechanisms in IPCC AR4 Coupled Ocean–Atmosphere General Circulation Models
Publisher: American Meteorological Society
Abstract: Warmer SST and more rain in the Northern Hemisphere are observed year-round in the tropical eastern Pacific with southerly wind crossing the equator toward the atmospheric heating. The southerlies are minimal during boreal ...
Variability in the Southerly Flow into the Eastern Pacific ITCZ
Publisher: American Meteorological Society
Abstract: During boreal summer and fall, there is a strong southerly boundary layer flow across the equator into the east Pacific intertropical convergence zone (ITCZ). The modulation of this flow on synoptic to seasonal time scales ...
Cloud-Resolving Large-Eddy Simulation of Tropical Convective Development and Surface Fluxes
Publisher: American Meteorological Society
Abstract: loud-resolving large-eddy simulations (LES) on a 500 km ? 500 km periodic domain coupled to a thermodynamic ocean mixed layer are used to study the effect of large-scale moisture convergence M on the convective population ...
Simulating Radiative Fluxes through Southeastern Pacific Stratocumulus Clouds during VOCALS-REx
Publisher: American Meteorological Society
Abstract: ABSTRACTTime series of solar and thermal infrared radiative flux profiles are simulated with the Rapid Radiative Transfer Model (RRTM) using a hierarchy of constraints from radar reflectivity and passive microwave cloud ...
Stratocumulus Cloud-Top Height Estimates and Their Climatic Implications
Publisher: American Meteorological Society
Abstract: A depth-dependent boundary layer lapse rate was empirically deduced from 156 radiosondes released during six month-long research cruises to the southeast Pacific sampling a variety of stratocumulus conditions. The lapse-rate ...
Thermodynamic and Aerosol Controls in Southeast Pacific Stratocumulus
Publisher: American Meteorological Society
Abstract: near-large-eddy simulation approach with size-revolving (bin) microphysics is employed to evaluate the relative sensitivity of southeast Pacific marine boundary layer cloud properties to thermodynamic and aerosol parameters. ...
Cold Pools and Their Influence on the Tropical Marine Boundary Layer
Publisher: American Meteorological Society
Abstract: old pools dominate the surface temperature variability observed over the central Indian Ocean (0°, 80°E) for 2 months of research cruise observations in the Dynamics of the Madden?Julian Oscillation (DYNAMO) experiment in ...
Surface Flux Observations on the Southeastern Tropical Pacific Ocean and Attribution of SST Errors in Coupled Ocean–Atmosphere Models
Publisher: American Meteorological Society
Abstract: A new dataset synthesizes in situ and remote sensing observations from research ships deployed to the southeastern tropical Pacific stratocumulus region for 7 years in boreal fall. Surface meteorology, turbulent and radiative ...
