RISOn the Dynamics of Intraseasonal Oscillations and ENSO
Publisher: American Meteorological Society
Abstract: The rudiments of a self-consistent theory of intraseasonal and interannual variability for the tropical ocean-atmosphere system are presented. In this paper we study some basic properties of low frequency phenomena in the ...
Origin of Low Frequency (Intraseasonal) Oscillations in the Tropical Atmosphere. Part III: Monsoon Dynamics
Publisher: American Meteorological Society
Abstract: This is the third in a series of papers to study the origin of intraseasonal oscillations. In this paper, we address the issue of the interaction of the monsoon large-scale circulation and intraseasonal oscillations. We ...
Origin of Low-Frequency (Intraseasonal) Oscillations in the Tropical Atmosphere. Part I: Basic Theory
Publisher: American Meteorological Society
Abstract: A theory of the origin of intraseasonal oscillations of the tropical atmosphere is presented and tested by simple model experiments. This study forces on the validation of the basic theory against key features of the ...
Wavelets, Period Doubling, and Time–Frequency Localization with Application to Organization of Convection over the Tropical Western Pacific
Publisher: American Meteorological Society
Abstract: In this paper, preliminary results in using orthogonal and continuous wavelet transform (WT) to identify period doubling and time-frequency localization in both synthetic and real data are presented. First, the Haar WT is ...
Climate Signal Detection Using Wavelet Transform: How to Make a Time Series Sing
Publisher: American Meteorological Society
Abstract: In this paper, the application of the wavelet transform (WT) to climate time series analyses is introduced. A tutorial description of the basic concept of WT compared with similar concepts used in music, is also provided. ...
Influences of Sea Surface Temperature and Ground Wetness onAsian Summer Monsoon
Publisher: American Meteorological Society
Abstract: The authors have conducted a series of experiments with a general circulation model to understand the influences of sea surface temperature (SST) and ground wetness (GW) (measured by snow amount and soil moisture content) ...
Seasonal Variation, Abrupt Transition, and Intraseasonal Variability Associated with the Asian Summer Monsoon in the GLA GCM
Publisher: American Meteorological Society
Abstract: In this paper, a description of the global and regional features of the Asian summer monsoon in the Goddard Laboratory Atmospheres (GLA) general circulation model (GCM) is presented based on a 10-yr (1979?1988) integration ...
Interannual, Decadal–Interdecadal, and Global Warming Signals in Sea Surface Temperature during 1955–97
Publisher: American Meteorological Society
Abstract: Sea surface temperature (SST) data from the NOAA analysis for the period of 1955?97 are used to identify dominant spatial and temporal patterns associated with interannual, decadal?interdecadal variabilities, and global ...
Dynamics of Atmospheric Teleconnections during the Northern Summer
Publisher: American Meteorological Society
Abstract: In this paper, the mechanisms of northern summertime teleconnections are investigated using a barotropic model. In a series of numerical experiments we study the atmospheric response over the eastern Pacific-North America ...
Coherent Modes of Global SST and Summer Rainfall over China: An Assessment of the Regional Impacts of the 1997–98 El Niño
Publisher: American Meteorological Society
Abstract: In this paper, the authors have identified three coherent modes of summertime rainfall variability over China and global sea surface temperature (SST) for the period of 1955?98 by Singular Value Decomposition. Based on ...
