RISDiagnosis of Convective and Mesoscale Motions During Phase IH of Gate
Publisher: American Meteorological Society
Abstract: Observational evidence from GATE suggests that a significant fraction of precipitation in tropical disturbances over the eastern Atlantic occurs beneath anvil-type mesoscale convective systems that are frequently associated ...
Large-Scale Effects of Deep Convection on the GATE Tropical Boundary Layer
Publisher: American Meteorological Society
Abstract: The large-scale response of the atmospheric boundary layer to the passage of tropical wave disturbances is investigated. Observations from GATE indicate that during periods of extensive deep convective activity rather ...
Short-Term Variations of the Tropopause Height over the Winter MONEX Area
Publisher: American Meteorological Society
Abstract: An observational study of short-term (?1 week) tropical tropopause height variations has been undertaken using measurements from the December 1978 Winter Monsoon Experiment (Winter MONEX). Sounding data from three Soviet ...
Effects of Cumulus Convection on the Structure and Growth of the Mixed Layer over South Florida
Publisher: American Meteorological Society
Abstract: Composites of rawinsonde observations of the subcloud layer over south central Florida obtained during the 1975 Florida Area Cumulus Experiment are presented. At a single location south of Lake Okeechobee three soundings ...
Characteristic Structure and Growth of the Nonprecipitating Cumulus Layer over South Florida
Publisher: American Meteorological Society
Abstract: A study has been carried out of the structure of the planetary boundary layer over south central Florida under locally undisturbed conditions using data from the 1975 Florida Area Cumulus Experiment (FACE). From a series ...
The Role of Convective-Scale Precipitation Downdrafts in Cumulus and Synoptic-Scale Interactions
Publisher: American Meteorological Society
Abstract: A diagnostic model has been developed to determine the contribution by convective-scale precipitation downdrafts to the total cumulus fluxes of mass, heat and moisture an the synoptic scale. Populations of cumulus clouds ...
Partitioning Tropical Heat and Moisture Budgets into Cumulus and Mesoscale Components: Implications for Cumulus Parameterization
Publisher: American Meteorological Society
Abstract: Results from recent heat and moisture budget studies of tropical mesoscale convective systems have been used to partition the total heating in tropical disturbances into cumulus and mesoscale components The mesoscale ...
The Effects of Cloud Detrainment on the Diagnosed Properties of Cumulus Populations
Publisher: American Meteorological Society
Abstract: Lateral detrainment from cumulus updrafts and its effect on the properties of cumulus cloud populations (as determined from large-scale observations) are examined. This detrainment, which can be related to the cumulus life ...
Cumulus Transports in a Tropical Wave Composite for Phase III of GATE
Publisher: American Meteorological Society
Abstract: A diagnostic study has been carried out of convective transports in tropical African wave disturbances that occurred during GATE. Data from the Reed et al. (1977) three-dimensional composite of eight wave disturbances ...
