TLDR
A seasonally dependent upper-tropospheric cooling leads to a clear seasonality of interdecadal changes in the atmospheric general circulation and precipitation against their normal seasonal cycle over East Asia as discussed by the authors.
Abstract
A significant interdecadal cooling with vivid seasonality and three-dimensional (3D) structure is first revealed in the upper troposphere and lower stratosphere over East Asia. A robust upper-tropospheric cooling appears in March and has two peaks in April and August, but in June, a moderate upper-tropospheric warming interrupts the cooling, while strong cooling occurs in the lower stratosphere. The seasonally dependent upper-tropospheric cooling leads to a clear seasonality of interdecadal changes in the atmospheric general circulation and precipitation against their normal seasonal cycle over East Asia. In March, precipitation over southern China (south of 26°N) has increased in accordance with the strong upper-tropospheric cooling occurring in northeast Asia. In April and May, following the southward extension and intensification of the upper-tropospheric cooling, the normal seasonal march of the monsoon rainband has been interrupted, resulting in a drying band to the south of the Yangtze Rive...

Why the Western Pacific Subtropical High Has Extended Westward since the Late 1970s

TL;DR: In this paper, the authors suggest that the negative heating in the central and eastern tropical Pacific and increased convective heating in equatorial Indian Ocean/ Maritime Continent associated with IWP warming are in favor of the westward extension of WPSH.

Detecting and understanding the multi-decadal variability of the East Asian Summer Monsoon: Recent progress and state of affairs

TL;DR: In this paper, a review is presented on the proposed explanations to the observed changes in the East Asian summer monsoon (EASM) during the 20th century. But it seems still unclear whether human activities and global warming are playing significant roles.

Responses of East Asian summer monsoon to historical SST and atmospheric forcing during 1950-2000

TL;DR: In this article, a series of simulations using the national center for atmospheric research (NCAR) community atmospheric model version 3 (CAM3) and the geophysical fluid dynamics laboratory (GFDL) atmospheric model 2.1 (AM2.1) are analyzed.

Seasonally evolving dominant interannual variability modes of East Asian climate.

TL;DR: In this article, a season-reliant empirical orthogonal function (S-EOF) analysis is applied to seasonal mean precipitation over East Asia for the period of 1979-2004.

The NCEP/NCAR 40-Year Reanalysis Project

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.

ENSO-like Interdecadal Variability: 1900–93

TL;DR: In this paper, the authors compare the structure of the interannual variability associated with the ENSO cycle and documents its time history back to 1900, using the leading EOFs of the SST anomaly and anomaly deviation fields in various domains and the associated expansion coefficient (or principal component) time series, which are used to construct global regression maps of SST, sea level pressure (SLP), and a number of related variables.

Decadal atmosphere-ocean variations in the Pacific

TL;DR: A decade-long change in the atmospheric circula- tion throughout the troposphere revealed a deeper and eastward shifted Aleutian low pressure system in the winter half year which advected warmer and moister air along the west coast of North America and into Alaska and colder air over the north Pacific.

Climate Effects of Black Carbon Aerosols in China and India

TL;DR: A global climate model used to investigate possible aerosol contributions to trends in China and India found precipitation and temperature changes in the model that were comparable to those observed if the aerosols included a large proportion of absorbing black carbon (“soot”), similar to observed amounts.
