RISInternally Generated and Externally Forced Multidecadal Oceanic Modes and Their Influence on the Summer Rainfall over East Asia
Publisher: American Meteorological Society
Abstract: AbstractInterdecadal oceanic variabilities can be generated from both internal and external processes, and these variabilities can significantly modulate climate on global and regional scales, including the warming slowdown ...
How Would the Twenty-First-Century Warming Influence Pacific Decadal Variability and Its Connection to North American Rainfall: Assessment Based on a Revised Procedure for the IPO/PDO
Publisher: American Meteorological Society
Abstract: AbstractDecadal climate variability of sea surface temperature (SST) over the Pacific Ocean can be characterized by interdecadal Pacific oscillation (IPO) or Pacific decadal oscillation (PDO) based on empirical orthogonal ...
Megadroughts in the Indian Monsoon Region and Southwest North America and a Mechanism for Associated Multidecadal Pacific Sea Surface Temperature Anomalies
Publisher: American Meteorological Society
Abstract: A 1360-yr control run from a global coupled climate model (the Parallel Climate Model) is analyzed. It simulates ?megadroughts? in the southwestern United States and Indian monsoon regions. The megadroughts represent extreme ...
Decadal Prediction in the Pacific Region
Publisher: American Meteorological Society
Abstract: A ?perfect model? configuration with a global coupled climate model 30-member ensemble is used to address decadal prediction of Pacific SSTs. All model data are low-pass filtered to focus on the low-frequency decadal ...
Contributions of Interdecadal Pacific Oscillation and Atlantic Multidecadal Oscillation to Global Ocean Heat Content Distribution
Publisher: American Meteorological Society
Abstract: AbstractRegional sea surface temperature (SST) mode variabilities, especially the La Niña?like Pacific Ocean temperature pattern known as the negative phase of the interdecadal Pacific oscillation (IPO) and the associated ...
The Mid-1970s Climate Shift in the Pacific and the Relative Roles of Forced versus Inherent Decadal Variability
Publisher: American Meteorological Society
Abstract: A significant shift from cooler to warmer tropical Pacific sea surface temperatures (SSTs), part of a pattern of basinwide SST anomalies involved with a transition to the positive phase of the Interdecadal Pacific Oscillation ...
Response of the Atlantic Thermohaline Circulation to Increased Atmospheric CO2 in a Coupled Model
Publisher: American Meteorological Society
Abstract: Changes in the thermohaline circulation (THC) due to increased CO2 are important in future climate regimes. Using a coupled climate model, the Parallel Climate Model (PCM), regional responses of the THC in the North Atlantic ...
Impact of Atmospheric Intraseasonal Variability in the Indian Ocean: Low-Frequency Rectification in Equatorial Surface Current and Transport
Publisher: American Meteorological Society
Abstract: An ocean general circulation model (OGCM) is used to investigate the low-frequency (period longer than 90 days) rectification of atmospheric intraseasonal variability (10?90-day periods) in zonal surface current and transport ...
Budgets for Decadal Variability in Pacific Ocean Heat Content
Publisher: American Meteorological Society
Abstract: A slowdown in the rate of surface warming in the early 2000s led to renewed interest in the redistribution of ocean heat content (OHC) and its relationship with internal climate variability. We use the Community Earth ...
Winter Weather Patterns over Northern Eurasia and Arctic Sea Ice Loss
Publisher: American Meteorological Society
Abstract: sing NCEP?NCAR reanalysis and Japanese 25-yr Reanalysis (JRA-25) winter daily (1 December?28 February) data for the period 1979?2012, this paper reveals the leading pattern of winter daily 850-hPa wind variability over ...
