RISThe Amazon Energy Budget Using the ABLE-2B and FluAmazon Data
Publisher: American Meteorological Society
Abstract: Radiosonde and satellite data collected from the Atmosphere Boundary Layer Experiment?Wet Season and Amazon Water Vapor Flux Experiment are used to investigate the energy budget. The relationship between the cloud cover ...
Effect of Turbulence Parameterization on Assessment of Cloud Organization
Publisher: American Meteorological Society
Abstract: his study evaluates the cloud and rain cell organization in space and time as forecasted by a cloud-resolving model. The forecast fields, mainly describing mesoscale convective complexes and cold fronts, were utilized to ...
Tropical Atlantic Moisture Flux, Convection over Northeastern Brazil, and Pertinence of the PIRATA Network
Publisher: American Meteorological Society
Abstract: This study aims to examine the relationship between the tropical Atlantic latent heat flux and convective cloud coverage over northeast Brazil (NEB) during the four months of the main rainy season (February?May). The ...
The Amazonian Low-Level Jet and Its Connection to Convective Cloud Propagation and Evolution
Publisher: American Meteorological Society
Combining a Cloud-Resolving Model with Satellite for Cloud Process Model Simulation Validation
Publisher: American Meteorological Society
Abstract: Advances in computer power have made it possible to increase the spatial resolution of regional numerical models to a scale encompassing larger convective elements of less than 5 km in size. One goal of high resolution is ...
Drop Size Distribution Broadening Mechanisms in a Bin Microphysics Eulerian Model
Publisher: American Meteorological Society
Abstract: In this study, processes that broaden drop size distributions (DSDs) in Eulerian models with two-moment bin microphysics are analyzed. Numerous tests are performed to isolate the effects of different physical mechanisms ...
Intercomparison of Integrated Water Vapor Estimates from Multisensors in the Amazonian Region
Publisher: American Meteorological Society
Abstract: Water vapor is an atmospheric component of major interest in atmospheric science because it affects the energy budget and plays a key role in several atmospheric processes. The Amazonian region is one of the most humid on ...
Basis for a Rainfall Estimation Technique Using IR–VIS Cloud Classification and Parameters over the Life Cycle of Mesoscale Convective Systems
Publisher: American Meteorological Society
Abstract: This paper discusses the basis for a new rainfall estimation method using geostationary infrared and visible data. The precipitation radar on board the Tropical Rainfall Measuring Mission satellite is used to train the ...
Analysis of Relative Humidity Sensors at the WMO Radiosonde Intercomparison Experiment in Brazil
Publisher: American Meteorological Society
Abstract: The quality of the vertical distribution measurements of humidity in the atmosphere is very important in meteorology due to the crucial role that water vapor plays in the earth?s energy budget. The radiosonde is the humidity ...
Spatial Variability of the Background Diurnal Cycle of Deep Convection around the GoAmazon2014/5 Field Campaign Sites
Publisher: American Meteorological Society
Abstract: he isolation of the Amazon rain forest makes it challenging to observe precipitation forming there, but it also creates a natural laboratory to study anthropogenic impacts on clouds and precipitation in an otherwise pristine ...
