The East Asian winter monsoon (EAWM), however, is significantly intensified in northern East Asia, which is characterized by a significant surface cooling in northern East Asia and an acceleration of the jet stream around 40°N. Such an intensification is attributed to anthropogenic black carbon (BC)-induced Tibetan Plateau (TP) : Y. Jiang. Uncovering the role of the East Asian jet stream and heterogeneities in atmospheric rivers affecting the western United States.

Recent advances in the study of the characteristics, processes, and causes of spatio-temporal variabilities of the East Asian monsoon (EAM) system are reviewed in this paper. The understanding of the EAM system has improved in many aspects: the basic characteristics of horizontal and vertical structures, the annual cycle of the East Asian summer monsoon (EASM) system and the East Asian winter. The jet stream over East Asia–P aciﬁc is also asso- Variations of wintertime EASJ and EAPJ. in conne ction with large-scale cir culat-ions. An EOF analysis is applied to the winter normal-.
The jet streams can be further classified according to the features of the profiles. For East Asia (70°–° E), jet streams can be classified into winter subtropical jet streams (15°–° N), summer subtropical jet streams (°–60° N), and summer polar front jet streams (60°–° N).Author: Haishan Li, Ke Fan, Zhiqing Xu, Hua Li.

The long-term variations of east Asia jet stream in the wintertime Public Deposited. mb wind data from the First GARP Global Experiment are analyzed in the East Asia winter monsoon region. It is found that there exist slowly eastward-moving disturbances with a wind-speed maximum embedded in the jet stream (jet streak).

It is found that there exist slowly eastward-moving\ud disturbances with a wind. The upper-tropospheric westerly jet stream over subtropical East Asia and westem Pacific, often referred to as East Asian Jet (EAJ), is an important atmospheric circulation system in the Asian-Pacific--American (APA) region during winter.
It is characterized by variabilities on a wide range of time scales and exerts a strong impact on theFile Size: KB. of the Asian–Paciﬁc–American climate with the East Asian jet stream (EAJS).
With an emphasis on boreal winter seasons and on interannual timescales, they analyze the variations of the EAJS.
In East Asia, the climate variability in boreal winter is dominated by the East Asian winter monsoon (EAWM) system. The EAWM is one of the most energetic monsoon circulation systems affecting temperature and precipitation variations over East Asia in winter by: In fact, the simultaneous out‐of‐phase variation between the East Asian polar front jet and the East Asian plateau jet, and the 5 day lag variation between the ocean jet and the other two jets over the East Asian continent during the snowstorm period are also manifested in some other by: Abstract Interdecadal variations of the East Asian winter monsoon (EAWM) and their association with the quasi-stationary planetary wave activity are analyzed by using the yr European Centre for.
In this study, the influences of the East Asian jet stream (EAJS) and El Nifio/Southern Oscillation (ENSO) on the interannual variability of the East Asian winter climate are examined with a focus on the relative climate impacts of the two phenomena.
Although the variations of the. Seasonal variations of the synoptic-scale transient eddy activity (STEA) and the jet streams over East Asia are examined through analysis of the yr European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) by: This study investigates the linkage between East Asian winter monsoon (EAWM) variability and upper-level jets, with particular focus on the East Asian polar front jet (PJ) and its concurrent variation with the subtropical jet located to the south of the Tibetan Plateau (TSJ).
In winter, the EAWJ center is situated over the western Pacific Ocean and the intensity is reduced gradually from east to west over the East Asian region. In summer, the EAWJ center is located over the north of the Tibetan Plateau and the jet intensity is reduced evidently compared with that in by: The monthly mean geostrophic wind fields for January during – period are calculated by using data of hPa monthly mean height.
The relation between Asia Jetstream in winter and the important seasonal precipitation in East China is analysed. The analysis shows that the south branch of Jetstream is stronger (weaker) in winter, the rainfall will be more (less) than normal in the.
This study investigates the concurrent variations in the location and intensity of the East Asian subtropical jet (EASJ) and polar front jet (EAPJ) with a focus on the relationship between the variations and the atmospheric circulation in the mid-latitude region.
The possible mechanisms for the concurrent variations of the EASJ and EAPJ are explored. The wintertime upper-level zonal wind Cited by: 3.
Instead of conventional East Asian winter monsoon indices (EAWMIs), we simply use two large-scale teleconnection patterns to represent long-term variations in the EAWM.
First, the Urals blocking pattern index (UBI) is closely related to cold air advection from the high latitudes towards western Siberia, such that it shows an implicit linkage with the Siberian high intensity and the surface air. phases. The variation of upper level trough and jet stream over east Asia and the Siberian High in association of AO are suggested to explain the change of cold surge occurrences.

Res. Lett., 32, L,Cited by: East Asia is under the strong influence of the summer monsoon. The intense monsoon precipitation that occurs in early summer is known as “mei-yu” in China, “baiu” in Japan, and “changma” in the Koreas (Tao and Chen ).The mei-yu precipitation usually accounts for more than 20% of the annual precipitation and sometimes exceeds 50% in the Yangtze-Huai River basin (YHRB; 28°– Which of the countries in East Asia has the greatest amount of natural resources.

The term “western Paciﬁc jet stream” (WPJ) was used to denote the jet stream over the midlatitude Paciﬁc Ocean (Cressman, ).
Be-cause the dominant direction of the jet stream over East Asia–Paciﬁc is zonally westerly, the literature also generally refers to it as East Asian westerly jet stream (Yang et al., ; Mao et al., ).
On average, approximately two cold surges per month occur over East Asia in winter (Chen et al. They often cause heavy freezing precipitation and snowfall over East Asia (Chen ;Park et.

Nevertheless, using power spectrum analysis, Murakami ) found that the variance of the wintertime wind field is dominated by the long-term ( day) variations; short-term day) disturbances have much less power spectral density.Although the variations of the East Asian winter monsoon and the temperature and precipitation of China, Japan, and Korea are emphasized, the associated changes in the broad-scale atmospheric circulation patterns over Asia and the Pacific and in the extratropical North Pacific sea surface temperature (SST) are also investigated.Relationship between concurrent variation of the East Asian jet streams and precipitation in winter over southern China.
