RISA Comparison of the General Circulations of the Northern and Southern Hemispheres Based on Satellite, Multi-Channel Radiance Data
Publisher: American Meteorological Society
Abstract: Certain aspects of the general circulations of the Northern and Southern Hemispheres are compared using atmospheric structure obtained from Nimbus 3 Satellite Infrared Spectrometer (SIRS) data. Comparisons between the ...
Mean Meridional Circulation in the Southern Hemisphere Stratosphere Based on Satellite Information
Publisher: American Meteorological Society
Abstract: Atmospheric structure derived from satellite, multi-channel radiance data is used to calculate zonally- averaged vertical motions in the wintertime stratosphere of both hemispheres using a heat budget approach. The Northern ...
Seasonal Evolution and Variability Associated with the West African Monsoon System
Publisher: American Meteorological Society
Abstract: In this study, the seasonal variations in surface rainfall and associated large-scale processes in the tropical eastern Atlantic and West African region are investigated. The 6-yr (1998?2003) high-quality Tropical Rainfall ...
Precipitation and Temperature Variations on the Interannual Time Scale: Assessing the Impact of ENSO and Volcanic Eruptions
Publisher: American Meteorological Society
Abstract: he effects of ENSO and two large tropical volcanic eruptions (El Chichón, March 1982; Mt. Pinatubo, June 1991) are examined for the period of 1979?2008 using various satellite- and station-based observations of precipitation, ...
Spatial Patterns of Global Precipitation Change and Variability during 1901–2010
Publisher: American Meteorological Society
Abstract: his study examines global precipitation changes/variations during 1901?2010 by using the long-record GPCC land precipitation analysis, the NOAA/Cooperative Institute for Climate and Satellites (CICS) reconstructed (RECONS) ...
Precipitation Intensity Changes in the Tropics from Observations and Models
Publisher: American Meteorological Society
Abstract: AbstractTropical (30°N?30°S) interdecadal precipitation changes and trends are explored for the satellite era using GPCP monthly analyses and CMIP5 outputs and focusing on precipitation intensity distributions represented ...
Thunderstorm Cloud Height–Rainfall Rate Relations for Use with Satellite Rainfall Estimation Techniques
Publisher: American Meteorological Society
Abstract: Observational studies of thunderstorm cloud height-rainfall rate and cloud height-volume rainfall rate relations are reviewed with significant variations being noted among climatological regimes. Analysis of the Florida ...
Aircraft Multifrequency Passive Microwave Observations of Light Precipitation over the Ocean
Publisher: American Meteorological Society
Abstract: Aircraft passive microwave observations at 18, 37, 92, and 183 GHz of light oceanic precipitation are studied in conjunction with visible and infrared observations and ground-based radar data. Microwave signatures for ...
Infrared and Visible Satellite Rain Estimation. Part II: A Cloud Definition Approach
Publisher: American Meteorological Society
Abstract: This study examines the relationships between satellite infrared clouds and rainfall, and infrared-threshold visible clouds and rainfall. Clouds are defined by the outline of the 253 K isotherm. Cloud infrared area was ...
Infrared and Visible Satellite Rain Estimation. Part I: A Grid Cell Approach
Publisher: American Meteorological Society
Abstract: The relationships between satellite-viewed cloudy (or partly cloudy) grid cells and the variability of the precipitation contained therein are explored. Using a 32 km grid and 30 min interval visible, infrared and radar ...
