RISRadar Analysis of a Tropical Convective Boundary Layer with Shallow Cumulus Clouds
Publisher: American Meteorological Society
Abstract: A situation of fair weather cloudy convection is examined using a dual Doppler radar, environmental measurements and cloud photogrammetry. The convective layer is characterized by the interaction between the northward ...
Convective Organization in a Tropical Boundary Layer: An Interpretation of Doppler Radar Observations Using Asai's Model
Publisher: American Meteorological Society
Abstract: Convective structures in a tropical boundary layer were analyzed using two Doppler radars. Their spatial organization is examined, revealing favored directions of alignment of cells in the four cases studied. The effect ...
Dual Doppler Radar Investigation of the Tropical Convective Boundary Layer
Publisher: American Meteorological Society
Abstract: Radar observations of the convective boundary layer wore made during the ?COPT81? experiment in May?June 1981 over western Africa. The lower atmosphere was characterized by the interaction between the southerly monsoon and ...
An Integrated Approach to Estimate Instantaneous Near-Surface Air Temperature and Sensible Heat Flux Fields during the SEMAPHORE Experiment
Publisher: American Meteorological Society
Abstract: A new technique was developed to retrieve near-surface instantaneous air temperatures and turbulent sensible heat fluxes using satellite data during the Structure des Echanges Mer?Atmosphere, Proprietes des Heterogeneites ...
Trend and Variability of the Atmospheric Water Vapor: A Mean Sea Level Issue
Publisher: American Meteorological Society
Abstract: he wet tropospheric path delay is presently the main source of error in the estimation of the mean sea level by satellite altimetry. This correction on altimetric measurements, provided by a dedicated radiometer aboard the ...
A 1D-Var Approach to Retrieve Clear-Sky Wet Tropospheric Correction from Current and Future Altimetry Missions
Publisher: American Meteorological Society
Abstract: AbstractStatistical methods are usually used to provide estimations of the wet tropospheric correction (WTC), necessary to correct altimetry measurements for atmospheric path delays, using brightness temperatures measured ...
Evaluation of Latent Heat Flux Fields from Satellites and Models during SEMAPHORE
Publisher: American Meteorological Society
Abstract: Latent heat fluxes were derived from satellite observations in the region of Structure des Echanges Mer?Atmosphère, Propriétés des Hétérogénéités Océaniques: Recherche Expérimentale (SEMAPHORE), which was conducted near ...
Which Bulk Aerodynamic Algorithms are Least Problematic in Computing Ocean Surface Turbulent Fluxes?
Publisher: American Meteorological Society
Abstract: Bulk aerodynamic algorithms are needed to compute ocean surface turbulent fluxes in weather forecasting and climate models and in the development of global surface flux datasets. Twelve such algorithms are evaluated and ...
Trains of African Easterly Waves and Their Relationship to Tropical Cyclone Genesis in the Eastern Atlantic
Publisher: American Meteorological Society
Abstract: n this study, the relationship between trains of African easterly waves (AEWs) and downstream tropical cyclogenesis is studied. Based on 19 summer seasons (July?September from 1990 to 2008) of ERA-Interim reanalysis fields ...
Analysis of Strengthening and Dissipating Mesoscale Convective Systems Propagating off the West African Coast
Publisher: American Meteorological Society
Abstract: large number of Atlantic tropical depressions are generated in the eastern basin in relation to the African easterly wave (AEW) and embedded mesoscale convective systems (MCSs) coming from the African continent. In this ...
