Linking Observations of the Asian Monsoon to the Indian Ocean SST: Possible Roles of Indian Ocean Basin Mode and Dipole Mode
TLDR
In this article, the authors investigated the relationship between sea surface temperature (SST) in the tropical Indian Ocean (TIO) and the seasonal atmosphere circulation in the Asian monsoon region (AMR) using the maximum covariance analyses (MCAs).Abstract:
The authors investigate the relationship between sea surface temperature (SST) in the tropical Indian Ocean (TIO) and the seasonal atmosphere circulation in the Asian monsoon region (AMR) using the maximum covariance analyses (MCAs). The results show that the Asian monsoon circulation is significantly correlated with two dominant SST anomaly (SSTA) modes: the Indian Ocean Basin mode (IOB) and the Indian Ocean dipole mode (IOD). The peak SSTA of the IOB appears in spring and has a much stronger relationship with the Asian summer monsoon than the peak of the IOD does, whereas the peak SSTA for the IOD appears in fall and shows a stronger link to the Asian winter monsoon than to the Asian summer monsoon. In addition, the IOB in spring has a relatively stronger link with the atmospheric circulation in summer than in other seasons. The large-scale atmospheric circulation and SSTA patterns of the covariability of the first two dominant MCA modes are described. For the first MCA mode, a warm IOB, persis...read more

TL;DR: In this paper, a suite of new satellite measurements and numerical modeling was used to investigate the upwelling off the continental shelf of the northern South China Sea (SCS) in 1998 summer.

Normalizing the causality between time series.
TL;DR: An unusually strong one-way causality is identified from IBM to GE in their early era, revealing an old story, which has almost faded into oblivion, about "Seven Dwarfs" competing with a giant for the mainframe computer market.

The asymmetric influence of the positive and negative IOD events on China's rainfall
TL;DR: A JJA pIOD index can serve as a potential predictor for variations of boreal fall rainfall over southern China, as it is found to be asymmetricly influenced by the Indian Ocean Dipole (IOD).

The key oceanic regions responsible for the interannual variability of the western North Pacific subtropical high and associated mechanisms
TL;DR: In this article, it is recognized that five oceanic regions are responsible for the interannual variability of the WNPSH in summer, including the equatorial central-eastern Pacific Ocean, tropical Indian Ocean, subtropical western North Pacific, the vicinity of the maritime continent, and the tropical Atlantic Ocean.

Three Types of Indian Ocean Dipoles
TL;DR: In this paper, observational data and phase 5 of the Coupled Model Intercomparison Project (CMIP5) model outputs [the preindustrial (PI) control run of the Community Climate System Model, version 4 (CCSM4) and historical simulations of 17 CMIP5 models] are categorized into three types.

TL;DR: The NCEP/NCAR 40-yr reanalysis uses a frozen state-of-the-art global data assimilation system and a database as complete as possible, except that the horizontal resolution is T62 (about 210 km) as discussed by the authors.

A Dipole Mode in the Tropical Indian Ocean
TL;DR: An analysis of observational data over the past 40 years shows a dipole mode in the Indian Ocean: a pattern of internal variability with anomalously low sea surface temperatures off Sumatra and high seasurface temperatures in the western Indian Ocean, with accompanying wind and precipitation anomalies.

Some simple solutions for heat-induced tropical circulation.
TL;DR: In this article, a simple analytic model is constructed to elucidate some basic features of the response of the tropical atmosphere to diabatic heating, showing that there is considerable east-west asymmetry which can be illustrated by solutions for heating concentrated in an area of finite extent.

Pacific–East Asian Teleconnection: How Does ENSO Affect East Asian Climate?
Bin Wang,Renguang Wu,Xiouhua Fu +2 more
TL;DR: In this article, a teleconnection between the central Pacific and East Asia during the extreme phases of ENSO cycles is presented, which is mainly attributed to a positive thermodynamic feedback between the anticyclone and the sea surface cooling in the presence of mean northeasterly trades.

Coupled ocean–atmosphere dynamics in the Indian Ocean during 1997–98
TL;DR: It is concluded that the 1997–98 anomalies—in spite of the coincidence with the strong El Niño/Southern Oscillation event—may primarily be an expression of internal dynamics, rather than a direct response to external influences.
