Detection of a 40–50 Day Oscillation in the Zonal Wind in the Tropical Pacific
Roland A. Madden,Paul R. Julian +1 more
TL;DR: In this paper, a very pronounced maximum was noted in the co-spectrum of the 850- and 150-mb zonal wind components in the frequency range 0.0245-0.0190 day−1 (41-53 days period).
Journal ArticleDOI
Description of Global-Scale Circulation Cells in the Tropics with a 40–50 Day Period
Roland A. Madden,Paul R. Julian +1 more
TL;DR: In this article, a long time series (5-10 years) of station pressure and upper air data from stations located in the tropics are subjected to spectral and cross-spectral analysis to investigate the spatial extent of a previously detected oscillation in various variables with a period range of 40-50 days.
Journal ArticleDOI
Observations of the 40-50-day tropical oscillation - a review
Roland A. Madden,Paul R. Julian +1 more
TL;DR: The 40-50-day cyclone oscillation is the result of large-scale circulation cells oriented in the equatorial plane that move eastward from at least the Indian Ocean to the central Pacific as discussed by the authors.
Journal ArticleDOI
The Tropical Ocean‐Global Atmosphere observing system: A decade of progress
Michael J. McPhaden,Antonio J. Busalacchi,Robert E. Cheney,Jean-René Donguy,Kenneth S. Gage,David Halpern,Ming Ji,Paul R. Julian,Gary Meyers,Gary T. Mitchum,Pearn P. Niiler,Joël Picaut,Richard W. Reynolds,Neville Smith,Kensuke Takeuchi +14 more
TL;DR: A major accomplishment of the recently completed Tropical Ocean-Global Atmosphere (TOGA) Program was the development of an ocean observing system to support seasonal-to-interannual climate studies.
Journal ArticleDOI
A Study of the Southern Oscillation and Walker Circulation Phenomenon
Paul R. Julian,Robert M. Chervin +1 more
TL;DR: A survey of the literature dating back to the early 1920's along with some appropriate statistical studies delineate an atmospheric-oceanic phenomenon of considerable interest as mentioned in this paper, which is known as the Southern Oscillation.
