Large-Scale Kinetic Energy Spectra from Eulerian Analysis of EOLE Wind Data
Publisher: American Meteorological Society
Abstract: A data set of 56,000 winds determined from the horizontal displacements of EOLE balloons at the 200 mb level in the Southern Hemisphere during the period October 1971?February 1972 is utilized for the computation of ...
Relation between METEOSAT Water Vapor Radiance Fields and Large Scale Tropical Circulation Features
Publisher: American Meteorological Society
Abstract: Mean monthly images from the water vapor channel of METEOSAT characteristically contain large-scale spatial structures, especially in tropical regions. The aim of this paper is to establish connections between these ...
Past and Present Precipitations Related to Climate Changes—Methodologies and Perspectives
Publisher: American Meteorological Society
Abstract: A summary of the North Atlantic Treaty Organization's Advanced Research Workshop Global Precipitations and Climate Change that reviewed the current understanding of global precipitation distribution, as related to climate ...
Cloud Cover Analysis from Satellite Imagery Using Spatial and Temporal Characteristics of the Data
Publisher: American Meteorological Society
Abstract: New developments of a cloud classification scheme based on histogram clustering by a statistical method are presented. Use of time series of geostationary satellite pictures as well as for construction of composite images ...
The Burst of the 1978 Indian Summer Monsoon as Seen from METEOSAT
Publisher: American Meteorological Society
Abstract: Low-level wind fields over the western Indian Ocean west of 65°E have been determined from the analysis of METEOSAT images from 10 to 22 May 1978 (one field every two days). The data show the abrupt change in the low-level ...
A Case Study of a Fluctuation of the Somali Jet During the Indian Summer Monsoon
Publisher: American Meteorological Society
Abstract: A fluctuation in the intensity of the Somali low-level jet flowing along the East African coast during the Indian summer monsoon is studied. It is shown that this variation of the intensity of cross-equatorial flow in ...
Study of Evaporation and Instability of Charged Water Droplets
Publisher: American Meteorological Society
Abstract: The wind correction to the evaporation rate of electrically suspended water droplets has been measured for Reynolds numbers between 1 and 6. The results agree well with those of Kinzer and Gunn. During evaporation, Rayleigh ...
Automatic Classification of Clouds on METEOSAT Imagery: Application to High-Level Clouds
Publisher: American Meteorological Society
Abstract: A statistical classification method based on clustering on three-dimensional histograms is applied to the three channels of the METEOSAT imagery [Visible (VIS)?Infrared Window (IR)?Infrared Water Vapor (WV)]. The results ...
Elements of the West African Monsoon Circulation Deduced from METEOSAT Cloud Winds and Simultaneous Aircraft Measurements
Publisher: American Meteorological Society
Abstract: Cloud winds derived from the European geostationary satellite METEOSAT for the region of the west African monsoon are validated by DC-7 aircraft measurements for the low levels of the tropical atmosphere. Since the two ...
Land Effect on the Diurnal Cycle of Clouds over the TOGA COARE Area, as Observed from GMS IR Data
Publisher: American Meteorological Society
Abstract: The diurnal cycle of clouds over the western equatorial Pacific region (15°S?15°N, 130°E?180°) is studied analyzing hourly GMS-4 infrared brightness temperature images during the intensive observation period (Nov 1992?Feb ...
