Interannual variability of spring rainfall over South China in association with the North Pacific Oscillation and North Atlantic Oscillation as revealed by reanalysis data and CMIP6 simulations
The interannual variability of South China spring rainfall (SCSR) is examined in relation to the North Pacific Oscillation (NPO) and North Atlantic Oscillation (NAO) based on longer-term reanalysis datasets an...

Sea surface temperature anomaly of Southwest Pacific dipole in boreal Winter–Spring: a mechanism for the Indian Ocean Dipole
The formation mechanisms of the Indian Ocean Dipole (IOD) have been studied extensively. However, few studies have considered the influence of the South Pacific atmosphere and sea surface temperature (SST) var...

Open AccessAspects of potential vorticity circulation in the Northern Hemisphere: climatology and variation
This study revisits the concept of potential vorticity (PV) circulation (PVC) and presents new findings. Results suggest that PVC can cross the isentropic surface. The gross PV in the Northern Hemisphere (NH) ...

Open AccessInterannual impact of tropical southern Atlantic SST on surface air temperature over East Asia during boreal spring
Using reanalysis data and simulations, this study revealed a pronounced negative interannual relationship between tropical southern Atlantic (TSA) sea surface temperature (SST) and East Asian surface air tempe...

Open AccessTwo types of Tibetan Plateau vortex genesis in June and the associated mechanisms
The Tibetan Plateau vortex (TPV) is a key system triggering rainfall over the Tibetan Plateau (TP) during the boreal summer. The TPV genesis mechanisms are complicated and its classification is a great challen...

Open AccessLinkage between cross-equatorial potential vorticity flux and surface air temperature over the mid–high latitudes of Eurasia during boreal spring
The source of potential vorticity (PV) for the global domain is located at the Earth’s surface. PV in one hemisphere can exchange with the other through cross-equatorial PV flux (CEPVF). This study investigate...

Open AccessPotential vorticity perspective of the genesis of a Tibetan Plateau vortex in June 2016
At midnight on 27–28 June 2016, a Tibetan Plateau (TP) Vortex (TPV) generated over the western TP that subsequently caused a downstream record-breaking rainstorm and extremely severe natural disaster. Based on...

Open AccessA dynamic and thermodynamic coupling view of the linkages between Eurasian cooling and Arctic warming
Investigating the contrast between wintertime warming in the Arctic and cooling in Eurasia is of great importance for understanding regional climate change. In this study, we propose a dynamic and thermodynami...

Open AccessSea ice loss of the Barents-Kara Sea enhances the winter warming over the Tibetan Plateau
The Tibetan Plateau (TP) is known as one of the most sensitive regions to climate change, and it has experienced accelerated warming in recent decades. However, to what degree the TP warming amplification rela...

Impact of potential vorticity anomalies around the eastern Tibetan Plateau on quasi-biweekly oscillations of summer rainfall within and south of the Yangtze Basin in 2016
Six persistent heavy rainfall events that occurred mostly over Hubei–Anhui–Jiangxi (HAJ) provinces within and south of the middle–lower Yangtze Basin during the summer of 2016 were regulated by the 10–20-day q...

Open AccessImpact of North Atlantic SST and Tibetan Plateau forcing on seasonal transition of springtime South Asian monsoon circulation
The South Asian circulation and precipitation in spring shows a clear seasonal transition and interannual variation. We investigate how the North Atlantic sea surface temperature (SST) and Tibetan Plateau (TP)...

Article
Open AccessThe role of air–sea interactions in regulating the thermal effect of the Tibetan–Iranian Plateau on the Asian summer monsoon
The thermal effect of the Tibetan–Iranian Plateau (TIP) on the Asian summer monsoon and the role of air–sea interactions over the Indian Ocean in regulating the effects of the TIP are explored. The results dem...

Climatology of tracked persistent maxima of 500-hPa geopotential height
Persistent open ridges and blocking highs (maxima) of 500-hPa geopotential height (Z500; PMZ) adjacent in space and time are identified and tracked as one event with a Lagrangian objective approach to derive t...

Tracking the delayed response of the northern winter stratosphere to ENSO using multi reanalyses and model simulations
The concurrent effects of the El Niño-Southern Oscillation (ENSO) on the northern winter stratosphere have been widely recognized; however, the delayed effects of ENSO in the next winter after mature ENSO have...

Open AccessLocation and variation of the summertime upper-troposphere temperature maximum over South Asia
The upper-troposphere-temperature-maximum (UTTM) over South Asia is a pronounced feature in the Northern Hemisphere summer. Its formation mechanism is still unclear. This study shows that the latitude location...

Influences of ENSO on the vertical coupling of atmospheric circulation during the onset of South Asian summer monsoon
Based on multiple sources of atmospheric and oceanic data, this study performs a series of composite analysis of the South Asian summer monsoon (SASM) onset against ENSO events, and indicates that warm/cold EN...

Interannual variability of the spring atmospheric heat source over the Tibetan Plateau forced by the North Atlantic SSTA
Data analysis indicates that the interannual variability of the spring atmospheric heat source over the Tibetan Plateau (TP) depends largely on the intensity of the overlying subtropical westerly jet (WJ), whi...

Open AccessAsian summer monsoon onset barrier and its formation mechanism
The onset process of Asian summer monsoon (ASM) is investigated based on diagnostic analysis of observations of precipitation and synoptic circulation. Results show that after the ASM commences over the easte...
