RISFour Years of Tropical ERA-40 Vorticity Maxima Tracks. Part II: Differences between Developing and Nondeveloping Disturbances
Publisher: American Meteorological Society
Abstract: Using a subset of the relative vorticity maxima (VM) tracks described in Part I, large-scale environmental fields, cold cloud area, and rainfall area are used to discriminate between developing and nondeveloping tropical ...
The Role of Organized Unsaturated Convective Downdrafts in the Structure and Rapid Decay of an Equatorial Disturbance
Publisher: American Meteorological Society
Abstract: The Line Islands Experiment, conducted on and near Palmyra, Fanning and Christmas Islands during February-April 1967, produced extensive data on disturbances of the equatorial trough zone. One disturbance which passed ...
Deep Cumulonimbus Cloud Systems in the Tropics with and without Lightning
Publisher: American Meteorological Society
Abstract: The thunderstorm frequency over the oceans during the Global Atmospheric Research Program Atlantic Tropical Experiment is quantified by examination of over 20 000 surface hourly observations from research ships. The overall ...
Differences between the Surface Precipitation Estimates from the TRMM Precipitation Radar and Passive Microwave Radiometer Version 7 Products
Publisher: American Meteorological Society
Abstract: ith 15 yr of the Tropical Rainfall Measuring Mission (TRMM) observations, the passive microwave radiometers [TRMM Microwave Imager (TMI)] and the precipitation radar (PR) report a close geographical distribution of annual ...
“Warm Rain” in the Tropics: Seasonal and Regional Distributions Based on 9 yr of TRMM Data
Publisher: American Meteorological Society
Abstract: How much precipitation is contributed by warm rain systems over the tropics? What is the typical size, intensity, and echo top of warm rain events observed by the Tropical Rainfall Measuring Mission (TRMM) Precipitation ...
Contribution of Tropical Cyclones to the Global Precipitation from Eight Seasons of TRMM Data: Regional, Seasonal, and Interannual Variations
Publisher: American Meteorological Society
Abstract: Based on the University of Utah Tropical Rainfall Measuring Mission (TRMM) precipitation feature (PF) database, tropical cyclone PFs (TCPFs) are identified for over 600 storms that reached tropical storm intensity level ...
Environmental Variability during TOGA COARE
Publisher: American Meteorological Society
Abstract: This study provides quantitative estimates of the thermodynamic and kinematic structures of the troposphere during various convective regimes observed during the Tropical Ocean Global Atmosphere Coupled Ocean?Atmosphere ...
Observations of Seven African Easterly Waves in the East Atlantic during 2006
Publisher: American Meteorological Society
Abstract: The African Monsoon Multidisciplinary Analyses (AMMA) experiment and its downstream NASA extension, NAMMA, provide an unprecedented detailed look at the vertical structure of consecutive African easterly waves. During ...
Retrieval of Hydrometeor Profiles in Tropical Cyclones and Convection from Combined Radar and Radiometer Observations
Publisher: American Meteorological Society
Abstract: A retrieval algorithm is described to estimate vertical profiles of precipitation ice water content and liquid water content in tropical cyclones and convection over ocean from combined spaceborne radar and radiometer ...
Mesoscale Events within a GATE Tropical Depression
Publisher: American Meteorological Society
Abstract: A tropical depression which intensified quite close to Dakar on 15 July 1974 was one of the strongest weather systems investigated during the GATE field program. A coordinated data set, consisting of satellite, radar, ...
