Summary: The study reveals the interannual variability in the southern Bay of Bengal cold pool (SCP) and its relationship with El Nino-Southern Oscillation (ENSO) events. The warming (cooling) anomaly of the SCP is induced by El Nino (La Nina) and is influenced by the southwest monsoon current (SMC) and atmospheric heating. These findings contribute to a better understanding of the regional climate fluctuation in the Bay of Bengal.

Summary: The North Pacific Oscillation (NPO) plays a role in triggering El Nino-Southern Oscillation (ENSO) through the seasonal footprinting mechanism (SFM). The efficiency of SFM varies among models and depends on the background mean state of the model. Greater intensification of the northern branch of the Pacific intertropical convergence zone (ITCZ) leads to stronger SFM efficiency and better triggers ENSO events.

Summary: The study demonstrates that the duration of El Nino events can be predicted based on their onset timing, with initial ocean conditions playing a crucial role in determining whether the event will terminate or persist. The ensemble spread in duration results from variations in surface wind over the western equatorial Pacific following the peak, which leads to different outcomes in September-initialized simulations compared to April-initialized simulations.

Summary: This study investigates the impact of El Nino-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) events on malaria transmission intensity in India. The results show that La Nina years pose a greater threat of malaria, particularly in densely populated Indian states. During El Nino years, malaria transmission intensity greatly reduces in most parts of India, except for specific regions. Positive IOD years lead to an increase in malaria transmission intensity over central India and coastal regions, while negative IOD years show the opposite effect. The study highlights the significant implications of ENSO and IOD on malaria intensity and distribution in a warming world, especially for densely populated Indian states.

Summary: The study investigated the response of phytoplankton and particulate organic carbon (POC) to the Typhoon Lekima event in the Yellow-Bohai Sea. It found that weakened Typhoon Lekima led to enhanced upwelling, strengthened currents, and increased terrestrial runoff in the region. The study also observed changes in Chl-a and POC concentrations post-typhoon, with a decrease in the Bohai Sea but an increase in the Yellow Sea, attributed to different factors such as nutrient input and water exchange.

Summary: Despite various measurements to improve saline-alkaline soils, soil organic matter (SOM) remains low in most salt-affected agricultural soils. This study found that the stability of SOM in salt-affected soils was weaker, leading to greater desorption. However, treatments with different soil ameliorants increased soil microbial biomass and improved soil properties. The results also indicated that there was a decoupling between carbon and nitrogen cycles, which might have implications for SOM stability.

Summary: This study examines the drivers behind the increasing trend in the Genesis Potential Index (GPI) of tropical cyclones in the Arabian Sea during the post-monsoon season. The study finds that increased atmospheric moisture loading, ocean heat content, and reduced vertical wind shear are the main factors contributing to the intensification of cyclone GPI. The study also identifies the influence of changes in the northern high-latitude climate on the cyclone genesis through the alteration of the subtropical jet and upper atmospheric circulation.

Summary: Through a field experiment, we found that biochar amendment and straw incorporation had a seasonal variation in their effects on soil heterotrophic respiration and desorption of soil organic carbon. CO2 efflux showed a significant exponential relationship with temperature, and was significantly higher in summer under straw incorporation compared to biochar amendments and without amendment. Biochar amendment also resulted in lower ratios of water extractable organic carbon to soil organic carbon and soil microbial biomass carbon to soil organic carbon. Overall, biochar amendment had a greater potential for reducing carbon emissions and desorption in cropland in the North China Plain.

Summary: This study investigates the dynamics of oxygen minimum zones (OMZs) in the tropical Pacific using a fully coupled basin-scale model. The results show that enhanced vertical mixing combined with a reduced O:C utilization ratio can improve the model's capability of reproducing the observed asymmetric OMZs. Physical supply, influenced by stronger vertical mixing to the south, plays a major role in regulating the asymmetry of the tropical Pacific's OMZs.
