Super Typhoon Mangkhut, which traversed the North Equatorial Current (NEC; 8-17 °N) in the western North Pacific in 2018, was the most intense Category-5 tropical cyclone (TC) with the longest duration in history-3.5 days. Here we show that the combination of two factors-high ocean heat content (OHC) and increased stratification - makes the NEC region the most favored area for a rapid intensification (RI) of super typhoons, instead of the Eddy Rich Zone (17-25 °N), which was considered the most relevant for RI occurrence. The high OHC results from a northward deepening thermocline in geostrophic balance with the westward-flowing NEC. The stratification is derived from precipitation associated with the Inter-Tropical Convergence Zone in the summer peak typhoon season. These factors, which are increasingly significant over the past four decades, impede the TC-induced sea surface cooling, thus enhancing RI of TCs and simultaneously maintaining super typhoons over the NEC region.

In recent years, fluorescence-switchable molecules have garnered significant attention as fluorescent dyes for super-resolution fluorescence microscopy, which is increasingly demanded in the field of biochemical imaging. Among such molecules, diarylethene-S,S,S',S'-tetraoxide derivatives have proven particularly promising due to their ability to achieve high contrast fluorescence switching. Diarylethenes incorporating perfluorocyclopentene as the ethene bridge have become the standard scaffold due to their excellent fatigue resistance and thermal stability.

In dramatic contrast to the continuous intensification of strong Atlantic hurricanes moving into the Gulf of Mexico, super typhoons (SuperTYs) originating from the Northwest Pacific significantly weaken after entering the South China Sea (SCS). Using an idealized cyclone intensity model, we show that this striking discrepancy results from the SCS's buffering effects, including persistent topographic blocking by the Philippine archipelago and seasonally shifting atmospheric-oceanic constraints. The archipelago accounts for ~54% of typhoon weakening throughout the season, while environmental factors explain the remaining ~46% with the significant seasonal dependence on strong SCS monsoon-induced vertical wind shear in summer (~30%) and ocean cooling in autumn (~37%).

This study investigated the temporal associations between psychological inflexibility, adaptive and maladaptive cognitive emotion regulation (CER), and posttraumatic stress symptoms (PTSS) in adolescents after a super typhoon. We surveyed adolescents 3 (November 2019, T1), 15 (November 2020, T2), and 27 (November 2021, T3) months after the super typhoon Lekima. Cross-lagged panel analysis was conducted among 1342 adolescents (Age: M = 14.

Numerous studies have demonstrated that restoring feelings of safety helps alleviate posttraumatic stress disorder (PTSD) based on cross-sectional designs. However, feelings of safety may be affected by PTSD over time. As a result, how safety and PTSD interact in victims and their coexisting patterns remain unclear, particularly in children who have suffered from natural disasters.

The extraordinary Super Typhoon (STY) Muifa (2022) made landfall four times and had a significant impact on the coastal regions from south to north of China. Although previous studies have demonstrated the 'pumping effect' of typhoons on the enhancement of reactive nitrogen (N) wet deposition over the ocean, it is uncertain how N deposition is influenced by typhoons that make prolonged mechanism due to multiple landfalls. In this study, the N wet deposition induced by STY Muifa was investigated from the perspective of in- and below-cloud processes based on the Nested Air Quality Prediction Modeling System with an online tracer-tagging module.
