These storms are recognized as one of nature's most hazardous weather phenomena. However, traditional typhoon track prediction methods face certain limitations in handling complex meteorological data and multi-dimensional features. To improve prediction accuracy, this paper proposes an improved Wide &amp; Deep framework. This framework utilizes a Stacked Two-layer Long Short-Term Memory (S2-LSTM) encoder in the Wide branch to model the sequential features of typhoon tracks, and incorporates a Multi-ConvGRU in the Deep branch to handle three-dimensional meteorological data. Following a dynamic/static feature decomposition, the S2-LSTM encoder processes a subset of dynamic features, effectively integrating typhoon position, wind speed, and rate-of-change information from multiple time steps to better capture the temporal evolution patterns of typhoon movement. Furthermore, a Coordinate Attention (CA) module is introduced, which captures positional dependencies along the vertical and horizontal dimensions within the feature maps through a factorized average pooling operation. This enhances the model's ability in identifying key areas within atmospheric fields, thus ensuring improved spatial precision in typhoon track forecasting. The model's efficacy was assessed with the 2020–2024 typhoon track dataset published by the China Meteorological Administration (CMA) and the ERA5 reanalysis product maintained by the European Centre for Medium-Range Weather Forecasts (ECMWF). The findings indicate how the two introduced enhancements to the model lead to higher precision for deep learning-based forecasts to a certain extent.</div></div>","PeriodicalId":44442,"journal":{"name":"Tropical Cyclone Research and Review","volume":"15 2","pages":"Pages 307-321"},"PeriodicalIF":4.1,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148208494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various hazards associated with TCs, such as extreme winds, heavy rain, storm surge and flooding, can incur multiple casualties and significant damages to property and infrastructure of the affected areas. Against the background of climate change, the latest assessments by the Expert Teams of the World Meteorological Organization and Typhoon Committee suggested that the TC intensity, precipitation rate and proportion of intense TCs in the western North Pacific (WNP) are expected to increase in a warming climate. Moreover, the sea level rises together with the projected increase in TC intensity will exacerbate storm surge and coastal inundation risks. Review of some recent studies further supports the findings of increasing TC risk in the WNP under climate change and provides more insights into various related topics, such as poleward migration, landfall intensity, rapid intensification and TC induced precipitation. In the context of extreme weather warnings, the United Nations launched the “Early Warnings for All (EW4All)” initiative in 2022 which is built on four pillars with a view to delivering effective and inclusive multi-hazard early warning systems for everyone on Earth. In Hong Kong, the Hong Kong Observatory (HKO) has implemented various weather and climate services over the past century with a number of the ongoing and recent services echoing with the four pillars of the EW4All initiative, especially for TC and rainstorm related hazards.

Warm (cold) core eddies, which are elevated (lowered) sea surface height structures with enhanced (diminished) heat content, respectively, can intensify (weaken) tropical cyclones by serving as a source of warm (cold) ocean water in the path of a storm. Oceanic anti-cyclone (cyclonic) The process of downwelling (upwelling) allows oceanic eddies to increase (reduce) heat content. In this study, we have conducted an Ocean Mixed Layer Heat budget analysis for distinct TCs over Bay of Bengal. Further we have examined the coherence between distinct ocean mixed layer budget terms and TC Genesis Potential Parameter (GPP) especially over warm and cold core eddies. Through this analysis, we found that the entrainment term has highest correlation with GPP, with correlation coefficient value of magnitude 0.68 with GPP, next to the entrainment the net heat flux term shows significant impact on GPP with correlation coefficient 0.42. Notably, unlike warm-core eddies, the pre-cyclonic relationship (5 days before passage) between mixed layer dynamics and GPP is absent in cold-core eddies. Furthermore, cold-core eddies have a lower association with different terms of mixed layer heat budget analysis and GPP than warm-core eddies. A prominent feature for warm-core eddies is that the net latent heat flux dominates in influencing GPP among the terms that determines net surface heat flux, however, such dominance of net heat flux is not observed for cold core eddies, which infers that the cold core eddy regions are relatively less influential in determining/impacting cyclone life cycle, compared to the warm core eddy regions. The present study offers valuable insights into the asymmetric role of oceanic eddies, particularly highlighting the pre-cyclonic ocean-atmosphere coupling over warm-core eddies, which should be incorporated into coupled forecast systems to enhance tropical cyclone intensity predictions in the Bay of Bengal.</div></div>","PeriodicalId":44442,"journal":{"name":"Tropical Cyclone Research and Review","volume":"15 2","pages":"Pages 322-338"},"PeriodicalIF":4.1,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148208492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The leading mode (EOF1) explains 35–50% of the variance in TC passage frequency and 43–59% in ACE across seasonal and annual analyses. This mode reveals that the primary pattern of TC activity affecting the Philippines is centered over the Philippine Sea, extending westward into the Philippines and northward toward Taiwan, China. For passage frequency, the spatial structure evolves seasonally with shifts in the monsoon trough (MT) and the Western North Pacific Subtropical High (WNPSH), highlighting the dynamical contrast between boreal summer (JJA) and autumn (SON). For ACE, the dominant pattern emphasizes open-ocean regions east and northeast of the Philippines, where TCs can intensify and persist. ENSO shows the strongest interannual relationships with both TC passage frequency and ACE, particularly during JJA, while the Pacific Decadal Oscillation (PDO) exhibits more seasonally consistent relationships at longer timescales.

CRs are detected in MCSs based on the Detect-And-Spread (DAS) algorithm applied on IR (InfraRed) Brightness Temperatures (IRBRT) for Bangalore station.

Detection accuracy was consistently highest during intensification, with F1 scores exceeding 0.80 in several basins, while genesis and decay remained more challenging due to weaker or more disorganized storm structures. Cross-basin experiments revealed substantial performance degradation when Northern Hemisphere models were applied to Southern Hemisphere storms, highlighting the influence of hemispheric rotation and storm asymmetry.
