RISThe Monsoon over the Indian Ocean During Summer 1975. Part II: Break and Active Monsoons
Publisher: American Meteorological Society
Abstract: In the second part of this paper we examine the active and break cycle of the monsoon during summer 1975. The time evolution of the flow over the Arabian Sea shocks that three main accelerations of the circulation occurred ...
Energy Dissipation Within Intermittent Clear Air Turbulence Patches
Publisher: American Meteorological Society
Abstract: Mean dissipation rates of kinetic energy in the lower stratosphere are estimated from data obtained with an instrumented, superpressure, constant-level balloon launched to measure the vertical wind shear at 200 mb. The ...
The Superpressue Balloon Sounding Technique for the Study of Atmospheric Meso-and Microscale Phenomena
Publisher: American Meteorological Society
Abstract: The history of the superpressure balloon sounding technique for scientific investigation of the dynamics of the atmosphere is noted. The technology of the balloon and associated pay-load is briefly described, and the ...
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 ...
The Monsoon over the Indian Ocean during Summer 1975. Part I: Mean Fields
Publisher: American Meteorological Society
Abstract: An assimillaiion of surface data collected from ship reports, land and islands stations during summer 1975 is presented. The domain of this study is the summer MONEX area (35?100°E, 25°N-25°S) and the period covers May, ...
Observational Evidence of Internal Inertia-Gravity Waves in the Tropical Stratosphere
Publisher: American Meteorological Society
Abstract: Twenty-nine highly accurate wind profiles up to 30 km obtained during four days of the GARP Atlantic Tropical Experiment (GATE) by tracking vertically ascending balloons with radar are presented and analyzed. The existence ...
Water Vapor Transport over the Indian Ocean during the 1979 Summer Monsoon. Part I: Water Vapor Fluxes
Publisher: American Meteorological Society
Abstract: Water vapor transport over the Indian Ocean during the 1979 summer monsoon is studied. The analysis is based on wind fields from the European Centre for Medium Range Weather Forecasts and humidity fields derived from a ...
The Propagation of Tropical Disturbances over the Indian Ocean during the Summer Monsoon
Publisher: American Meteorological Society
Abstract: Daily nephanalysis of NOAA 4 satellite visible images over the Indian Ocean during the 1975 summer monsoon was used to construct time-longitude sections of cloud cover during a month and a half. Tropical disturbances ...
Water Vapor Transport over the Indian Ocean during the 1979 Summer Monsoon. Part II: Water Vapor Budgets
Publisher: American Meteorological Society
Abstract: In this second part of the paper, moisture budgets over the Arabian Sea and the Bay of Bengal are investigated for the 1979 summer monsoon season. Over the Arabian Sea the different terms of the moisture balance equation, ...
