Summary: Based on high-resolution atmospheric simulations, two classes of cyclones originating from the tropics and extratropics passing the Kuroshio Extension region in the North Pacific in cold season are detected and tracked. The different cyclone development and water vapor restoration in the KE are primarily attributed to different preconditions of the two classes of cyclones.

Summary: A major ocean response to tropical cyclone wind is the mixing of warm sea-surface water with cool subsurface water, resulting in a decreased sea-surface temperature. The author found a linear relation between the temperature decrease and the parameters of the tropical cyclone and the ocean. This relation can be estimated from observations and the modelled temperature decrease is validated against satellite observations.

Summary: Proposals to cool sea surface temperatures using technology to weaken tropical cyclones have gained attention. Research suggests that artificially cooling the ocean can significantly weaken tropical cyclones, particularly in high sea surface temperature and deep ocean mixed layer environments. However, realistic simulations show that massive regions of artificially cooled ocean waters would be required to achieve a modest 15% weakening of a tropical cyclone two days before landfall, under ideal atmospheric and oceanic conditions.

Summary: Tropical cyclones are often accompanied by strong winds and torrential rains. The competition between the stabilizing effect of rainfall and wind-induced mixing, as well as the degree to which it modulates TC-induced sea surface cooling, remain unknown. This study shows that heavy rains under weak TCs can significantly reduce the magnitude of cold wakes induced by them, with the ocean surface freshening and cooling less.

Summary: The intensity of tropical cyclones is influenced by air-sea fluxes of enthalpy and momentum, with sea spray playing a crucial role in mediating these fluxes at high wind speeds. Parameterizing the influence of sea spray is essential in air-sea interaction schemes, but there is currently no consensus on the best parameterization for representing air-sea exchange in tropical cyclones, leading to substantially different intensity predictions. This paper reviews developments in parameterizations of sea spray-mediated fluxes and synthesizes common key findings across many studies.

Summary: Tropical cyclones generate large and wide cold wakes along their trajectories, impacting the evolution of the cyclones themselves and reducing cloud coverage and rainfall. This study sheds light on the mechanisms of air-sea feedbacks triggered by cold wakes, which may vary at different latitudes. Further research is needed to assess the significant impact of cyclone-induced cloud cover anomalies on Earth's radiative budget.

Summary: The study reveals the significant impact of different surface roughness schemes on simulating tropical cyclones over the Bay of Bengal. Opt2 and Opt1 experiments, after improving the ocean-atmosphere feedback in the model, show better performance in predicting the track, intensity, and precipitation of tropical cyclones.

Summary: The intensity of tropical cyclones is difficult to predict accurately in numerical weather models, making ensemble forecasting crucial. However, current ensemble prediction systems often only consider uncertainty in initial conditions and overlook model uncertainty, which can significantly affect the evolution of mesoscale features.

Summary: The meteorology community primarily assesses the accuracy of tropical cyclone forecasts by studying the errors in track and intensity. However, these metrics are often unrelated and conflicting. To improve intensity forecasts, it is necessary to improve the representation of physical processes at multiple scales, and model verification of the spatial structure of tropical cyclones can contribute to these improvements. Currently, there is limited research on the forecast model representation of wind fields, and more work is needed to understand the deficiencies in skillfully predicting the size of tropical cyclones.

Summary: The study develops a synthetic dataset of tropical cyclone wind and wave by combining computationally efficient parametric models and computationally intensive fully dynamic models with different model grid resolutions to address the mismatch between design requirements and observational history. Performance differences between various model approaches are outlined and recommendations for engineering are provided.

Summary: This study provides a comprehensive understanding of Australian tropical cyclones using artificial intelligence techniques. Regression, anomaly detection, and clustering methods were applied to a large cyclone database, resulting in critical insights on factors influencing cyclone pressure and the identification of anomaly conditions. The study also demonstrates the robustness of the AI algorithms and the system's potential for evidence-based policy decisions.

Summary: Global tropical cyclone-induced sea surface temperature cooling and surface chlorophyll-a concentration have significantly increased over the past 20-35 years, driven by an increase in the intensity of strong tropical cyclones. The increase in chlorophyll-a concentration, particularly in oligotrophic areas during the tropical cyclone season, has partially offset the overall decline in primary production under climate change.

Summary: This study finds that there is an overestimation of axis ratios (ARs) for raindrops when using 2D images for parameterization, especially for large raindrops and 2DVD raw products. This overestimation leads to an underestimation of differential reflectivity (Z(DR)) in simulated data and results in an underestimation of more than 20% for heavy rain rate estimation using polarimetric radar. In precipitating systems with drastic changes in raindrop size distribution, it is important to consider more realistic ARs.

Summary: Satellite observations show that after the passage of a tropical cyclone in the northwestern Pacific Ocean, sea surface temperature typically recovers within 30 days, depending on factors such as cooling intensity and cyclone strength. Mixed layer depth and upper layer thermocline temperature gradient are also important factors influencing the SST response to tropical cyclones.
