Enhanced biennial variability in the Pacific due to Atlantic capacitor effect

Nature Communications (2017)

Lei Wang Jin‐Yi Yu Houk Paek

Abstract The El Niño-Southern Oscillation (ENSO) and the variability in the Pacific subtropical highs (PSHs) have major impacts on social and ecological systems. Here we present an Atlantic capacitor effect mechanism to suggest that the Atlantic is a key pacemaker of the biennial variability in the Pacific including that in ENSO and the PSHs during recent decades. The ‘charging’ (that is, ENSO imprinting the North Tropical Atlantic (NTA) sea surface temperature (SST) via an atmospheric bridge mechanism) and ‘discharging’ (that is, the NTA SST triggering the following ENSO via a subtropical teleconnection mechanism) processes alternate, generating the biennial rhythmic changes in the Pacific. Since the early 1990s, a warmer Atlantic due to the positive phase of Atlantic multidecadal oscillation and global warming trend has provided more favourable background state for the Atlantic capacitor effect, giving rise to enhanced biennial variability in the Pacific that may increase the occurrence frequency of severe natural hazard events.

The impact of extratropics-arctic-seesaw of perturbation potential energy on surface air temperature in boreal winters

Atmospheric Science Letters (2015)

Lei Wang Zhanggui Wang Jianping Li Fei Zheng

Seesaw pattern of the perturbation potential energy in the extratropics and the Arctic (defined as PEAS) is observed. The PEAS is closely related to the Arctic Oscillation, kinetic energy and zonal wind in the middle- and high-latitude. The PEAS may influence atmospheric circulation via northern migration of anomalous Ferrel cell, accompanying by suppressed subtropical jet stream and enhanced polar jet stream. Anomalous warm conditions associated with the PEAS are observed in high-latitude of Eurasia, whereas cold anomalies are presented in Greenland, northeast Africa and southwest China, which is mainly attributed to the horizontal temperature advection.

Seasonal variability of eddy kinetic energy in the East Australian current region

Frontiers in Marine Science (2022)

Jia Liu Shaojun Zheng Ming Feng Lingling Xie Baoxin Feng

The East Australian Current (EAC) is an important western boundary current of the South Pacific subtropical Circulation with high mesoscale eddy kinetic energy (EKE). Based on satellite altimeter observations and outputs from the eddy-resolving ocean general circulation model (OGCM) for the Earth Simulator (OFES), the seasonal variability of EKE and its associated dynamic mechanism in the EAC region are studied. High EKE is mainly concentrated in the shear-region between the poleward EAC southern extension and the equatorward EAC recirculation along Australia's east coast, which is confined within the upper ocean (0-300 m). EKE in this area exhibits obvious seasonal variation, strong in austral summer with maximum (465±89 cm² s-²) in February and weak in winter with minimum (334±48 cm² s-²) in August. Energetics analysis from OFES suggests that the seasonal variability of EKE is modulated by the mixed instabilities composed of barotropic and baroclinic instabilities confined within the upper ocean, and barotropic instability (baroclinic instability) is the main energy source of EKE in austral summer (winter). The barotropic process is mainly controlled by the zonal shear of meridional velocities of the EAC southern extension and the EAC recirculation. The poleward EAC southern extension and the equatorward EAC recirculation are synchronously strengthened (weakened) due to the local positive (negative) sea level anomalies (SLA) under geostrophic equilibrium, and the barotropic instability dominated by zonal shear is enhanced (slackened), which results in a high (low) level of EKE in the EAC region.

Contrasting the Indian and western North Pacific summer monsoons in terms of their intensity of interannual variability and biennial relationship with ENSO

Atmospheric and Oceanic Science Letters (2020)

Baiyang Chen Lei Wang Minmin Wu

The intensity of interannual variability (IIV) of the monsoon and monsoon–ENSO biennial relationship (MEBR) were examined and compared for both the Indian summer monsoon (ISM) and western North Pacific summer monsoon (WNPSM) during 1958–2018. Covariability of the IIV and MEBR were identified for the two monsoons. When the MEBR was strong (weak), the IIV of the monsoon was observed to be large (small). This rule applied to both the ISM and WNPSM. Out-of-phase relationships were found between the ISM and the WNPSM. When the IIV and MEBR of the ISM were strong (weak), those of the WNPSM tended to be weak (strong). During the period with a stronger (weaker) ENSO–Atlantic coupling after (before) the mid-1980s, the IIV and MEBR of the WNPSM (ISM) were observed to be stronger. The increasing influences from the tropical Atlantic sea surface temperature (SST) may trigger the observed seesaw pattern of the ISM and WNPSM in terms of the IIV and MEBR multidecadal variability. The results imply that tropical Atlantic SST may need to be given more attention and consideration when predicting future monsoon variability of the ISM and WNPSM.

An Analysis of the Sea-Surface Thermal Fronts in the Northern Shelf Region of the South China Sea with Satellite Data

Qingdao Haiyang Daxue xuebao (2004)

Lei Wang

Based on seven years'(1993～1999) monthly mean SST satellite data, the feature of monthly changes for the thermal fronts in the Northern South China Sea is analyzed. Results show that the intraseasonal changes of the thermal fronts are distinct. Combining the wind satellite data, we analyze the effect of the northeast monsoon on the form and development of the thermal fronts. This study shows that the increase of the wind velocity of the northeast monsoon can strengthen the intensity of the thermal fronts. Through the contrast of SST features in February 1998 when Kuroshio intrusion was weak and in February 1999 when Kuroshio intrusion was strong, the effect of Kuroshio intrusion on the thermal fronts is analyzed. Strong Kuroshio intrusion can increase the intensity of the thermal front and can also affect the direction of the thermal front.
