RISRadiative Invigoration of Tropical Convection by Preceding Cirrus Clouds
Publisher: American Meteorological Society
Abstract: AbstractThis work seeks evidence for convective?radiative interactions in satellite measurements, with a focus on the variability over the life cycle of tropical convection in search of the underlying processes at a ...
Measuring Area-Averaged Vertical Motions with Dropsondes
Publisher: American Meteorological Society
Abstract: AbstractMeasurements of vertical profiles of areal-mean mass divergence, vorticity, and vertical velocity, based on dropsondes distributed over an area of 25 000 km2, are presented. The dropsondes were released with high ...
A Parameterization of the Cloudiness Associated with Cumulus Convection; Evaluation Using TOGA COARE Data
Publisher: American Meteorological Society
Abstract: A new parameterization of the cloudiness associated with cumulus convection is proposed for use in climate models. It is based upon the idea that the convection scheme predicts the local concentration of condensed water ...
An Assessment of the Primary Sources of Spread of Global Warming Estimates from Coupled Atmosphere–Ocean Models
Publisher: American Meteorological Society
Abstract: Climate feedback analysis constitutes a useful framework for comparing the global mean surface temperature responses to an external forcing predicted by general circulation models (GCMs). Nevertheless, the contributions ...
On the Role of Moist Processes in Tropical Intraseasonal Variability: Cloud–Radiation and Moisture–Convection Feedbacks
Publisher: American Meteorological Society
Abstract: Recent observations of the tropical atmosphere reveal large variations of water vapor and clouds at intraseasonal time scales. This study investigates the role of these variations in the large-scale organization of the ...
On the Role of Clouds and Moisture in Tropical Waves: A Two-Dimensional Model Study
Publisher: American Meteorological Society
Abstract: Observations show that convective perturbations of the tropical atmosphere are associated with substantial variations of clouds and water vapor. Recent studies suggest that these variations may play an active role in the ...
Observational Evidence for Relationships between the Degree of Aggregation of Deep Convection, Water Vapor, Surface Fluxes, and Radiation
Publisher: American Meteorological Society
Abstract: ropical deep convection exhibits complex organization over a wide range of scales. This study investigates the relationships between the spatial organization of deep convection and the large-scale atmospheric state. By ...
Indian Ocean Low Clouds during the Winter Monsoon
Publisher: American Meteorological Society
Abstract: While low-level clouds over the Pacific and Atlantic Oceans have been investigated extensively, low clouds over the Indian Ocean are not as well characterized. This study examines the occurrence of nonoverlapped low clouds ...
Identifying the Sources of Convective Memory in Cloud-Resolving Simulations
Publisher: American Meteorological Society
Abstract: AbstractConvection is often assumed to be controlled by the simultaneous environmental fields. But to what extent does it also remember its past behavior? This study proposes a new framework in which the memory of previous ...
Combining crowd-sourcing and deep learning to explore the meso-scale organization of shallow convection
Publisher: American Meteorological Society
Abstract: Humans excel at detecting interesting patterns in images, for example those taken from satellites. This kind of anecdotal evidence can lead to the discovery of new phenomena. However, it is often difficult to gather enough ...
