Summary: Understanding the different combinations of westward- (ISOw) and eastward-propagating intraseasonal oscillation (ISOe) is crucial for predicting the Madden-Julian Oscillation (MJO). This study reveals that the interaction between ISOw and ISOe can shape the diverse MJO propagations observed previously. The dry ISOw signals from the Central Pacific reinforce suppressed convection over the Western Pacific and weaken moist ISOe convection over the Maritime Continent. Thus, ISOw and ISOe play a significant role in influencing the MJO modes.

Summary: This study examines the governing dynamics behind the northward propagation of convection over the Arabian Sea and Bay of Bengal during summer monsoon. Using the vorticity budget equation, the study finds that the tilting term in the vorticity equation leads the precipitation maxima by a certain number of days in both regions. The study also highlights the stronger behavior of the tilting term over the Bay of Bengal and its association with the meridional gradients in vertical velocity. Furthermore, the study identifies the contribution of the vertical shear of mean meridional winds in driving the northward propagation over the Arabian Sea.

Summary: The study found significant decadal changes in the properties of the Intraseasonal Oscillation (ISO) since 1998, mainly in its evolution rather than its intensity. The boreal summer ISO has shown northeastward propagation since 1998, enhancing intraseasonal variability over the western North Pacific. Meanwhile, the Madden-Julian Oscillation (MJO) in boreal winter has shown minor changes in its barrier effect in the Maritime Continent and continues to propagate eastward.

Summary: This study focuses on the stand and jump types of the Madden-Julian oscillation (MJO). It reveals the influence of the westward-propagating wave (WPW), QBO, and ENSO on MJO propagation. The jump MJO is influenced by the QBO and ENSO, leading to independent convection over the Pacific, while the stand MJO is constrained by La Nina-like cool SST anomalies, preventing independent convection over the central Pacific.

Summary: The aim of this study is to investigate the characteristics of the intraseasonal oscillation (ISO) with a 10-30-day cycle over mid-high-latitude Eurasia during boreal summer. The leading mode of this ISO is determined using an extended empirical orthogonal function analysis. Through a phase composite analysis, it is observed that a southeastward-propagating wave train with a quasi-barotropic structure is present in Eurasia.

Summary: This study developed a linear moisture mode theory to investigate the intraseasonal oscillations in the tropical atmosphere. The results showed that there are an infinite number of normal modes for these moisture modes under the same parameter values. The idealized MJO solutions derived using different meridional moisture gradients bear similar meridional structure for planetary scale waves in the Earth-like atmosphere.

Summary: During boreal winter, the invasion of cold air in East Asia can lead to significant temperature drops, causing serious socioeconomic impacts. This study shows that the intensity of synoptic cold days in the East China Sea and Indochina Peninsula is increasing due to surface warming over the South China Sea and Philippine Sea. Numerical simulations confirm the oceanic forcing of the South China Sea and Philippine Sea on synoptic cold days in these regions. The warming enhances baroclinicity, intensifying meridional wind and cold advection.

Summary: In this study, a RuO2-modified NiFe-LDH catalyst was designed and synthesized for water splitting, combining the advantages of RuO2 and LDHs. The catalyst demonstrated overpotentials of 99 and 226 mV for the oxygen and hydrogen evolution reactions, respectively, to reach a current density of 10 mA cm(-2). Importantly, the RuO2/NiFe-LDH/NF catalyst exhibited a voltage of 1.52 V for water electrolysis at 10 mA cm(-2), which is significantly lower than the RuO2||Pt/C pair (1.64 V). Furthermore, the catalyst displayed excellent durability with negligible potential variation after more than 100 hours of stability testing. This work highlights the promising strategy of integrating RuO2 and NiFe-LDH for synthesizing robust catalysts for water electrolysis.

Summary: Hydrogen production by water electrolysis is a promising green hydrogen supply method. Transition metal sulfides, such as cobalt disulfide, have been extensively studied as alternative catalysts. However, the catalytic performance of cobalt disulfide itself is still insufficient for large-scale industrial applications, thus improving its performance remains the focus of research.

Summary: Marine heatwaves (MHWs) are extreme climatic events that have a significant impact on marine ecosystems and services worldwide. We examined the spatiotemporal variation of summer MHWs in the north Indian Ocean (NIO) and found two main MHW modes associated with distinct sea surface temperature patterns. These MHW modes significantly influence the distribution and intensity of summer precipitation in the NIO.

Summary: This study examines the relationship between AO and winter synoptic temperature variability (STV) over the Northern Hemisphere using 34 CMIP5/CMIP6 model outputs. Most models fail to capture the correct AO-STV pattern in historical simulations due to significant model bias. The bias of AO-STV relationship simulations can be traced back to AO pattern simulations, with HPS models overall capturing the intensity in the North Pacific and North Atlantic center of AO, and LPS models overestimating the North Pacific center and underestimating the North Atlantic center.

Summary: Passivating the recombination in a photocatalyst is a challenge for efficient photocatalytic CO2 reduction. The design of intrinsic built-in electric field in a single phased photocatalyst can facilitate transport without introducing extra side reactions. This study uses MoSxSeyNz to define localized built-in electric fields and shows that it improves the adsorption of intermediate products and lowers the energy for methanol-oriented photoproduction, resulting in a 162% increase in the photoproduction of methanol reduced from CO2.

Summary: In this study, a highly active and stable Fe single atomic catalyst with axial Fe-O coordination was developed through a fast medium-temperature pyrolysis process. The catalyst exhibited high performance in oxygen reduction reaction, with a high half-wave potential of 0.93 V (vs. RHE) and excellent stability. Density functional theory calculations revealed that the axial Fe-O coordination optimized the interactions between Fe and intermediates, enhancing the performance and stability of the catalyst. This strategy is believed to be easily applicable in the rational design of eco-friendly and future-oriented energy applications.

Summary: This study explores the modulation of the Pacific decadal oscillation (PDO) on the relationship between the occurrence position of rapid intensification (RI) events of tropical cyclones (TCs) over the western North Pacific (WNP) in boreal autumn and El Nino-Southern Oscillation (ENSO). The results suggest that the warm to cold phase change of the PDO affects the occurrence position of WNP RI events in El Nino and La Nina years. Furthermore, the study finds that the responses of the WNP environment to ENSO variation, the sea surface temperature in the north Indian Ocean, and the anomalous circulation in the WNP are associated with the thermodynamic conditions over the WNP.
