Summary: The 1933 Atlantic hurricane season was exceptionally active, setting multiple historical records with 20 named storms, 11 hurricanes, and 6 major hurricanes. Favorable dynamic conditions and above-normal tropical Atlantic sea surface temperatures created an optimal environment for hurricane formation and intensification. Statistical models used by Colorado State University predicted the high activity of the 1933 hurricane season.

Summary: The study proposes a new hurricane risk assessment model, C-3-HITS, which simulates North Atlantic tropical cyclone tracks and intensity based on early-season large-scale climate conditions. By adding two climate covariates for track simulation, the model's predictive efficacy is compared with an unconditional HITS application.

Summary: The study investigates the response of tropical cyclones to climate change using different models and methods. Results show that there will be an increase in intensity and frequency of storms in the future, with different models showing varying degrees of sensitivity to climate change effects.

Summary: This study investigates the mechanisms of inner-core sea surface cooling (SSCIC) induced by tropical cyclones (TCs) using a linear two-layer theory and OGCM experiments. The results suggest that the pattern of inner-core mixing can be explained by wind-driven currents, with the intensity of SSCIC inversely proportional to TC moving speed. The study emphasizes the different roles of mixing, upwelling, and horizontal advection for fast- and slow-moving TCs in influencing SSCIC.

Summary: This study analyzed in situ observations of precipitation and storm surges globally, finding that compound floods with marginal values exceeding the 98.5th percentile occur with shorter return periods in most areas. Cyclones, including tropical cyclones and extratropical cyclones, were identified as the major triggers of compound floods. Europe tends to experience extreme precipitation and extreme storm surges in different months, which contributes to the relatively lower probability of compound floods in the region. The comprehensive hazard assessment of global compound floods in this study provides important insights for flood risk management in coastal regions worldwide.

Summary: This study provides a comparative analysis of Hurricane Ida and other major landfalling hurricanes in the Gulf Coast, with a particular focus on Hurricane Katrina. The study finds that Hurricane Ida had a weaker postlandfall decay rate compared to Hurricane Katrina. Factors such as soil moisture and offshore environmental conditions played important roles in the weakening and intensification of the hurricanes.

Summary: This study investigates the intensity and spatial extent of rainfall caused by tropical cyclones in China. The results show that the most intense rainfall and largest spatial extent occur when a supertyphoon weakens to a tropical storm at landfall. The study also finds that tropical cyclone rainfall has become heavier in most coastal areas of China.

Summary: Analyses of two high-resolution reanalysis products indicate that high values of hurricane potential intensity (PI) are becoming more frequent and covering a larger area of the Atlantic, consistent with the previously reported lengthening of the tropical cyclone season. Specifically, the increase in high PI is most pronounced in the early months of the storm season in subtropical latitudes. The western subtropical Atlantic experiences an increase in mean PI, as well as the areal coverage and frequency of high PI throughout the storm season, with the length of the season with high PI growing since 1980. While the number of days with low vertical wind shear increases in the tropical North Atlantic during the early and middle months of the storm season, trends elsewhere are mixed and generally insignificant. The choice of pressure level(s) used to calculate a thermodynamic parameter, which measures the ratio of midlevel entropy deficits to the strength of surface fluxes, as well as subtle differences in temperature and humidity values near the surface in different reanalysis datasets, can lead to divergent results in metrics like the ventilation index that rely on its value. Projections from a high-resolution simulation for the rest of the twenty-first century suggest that the number of days with high PI is likely to continue increasing in the North Atlantic basin, particularly in the western subtropical Atlantic during the early and late months of the season.

Summary: This study presents an accurate precipitation climatology for tropical depression (TD), tropical storm (TS), and tropical cyclone (TC) occurrences over oceans using high-quality precipitation datasets and TC center positions. The study analyzes the impacts of TC movement direction and wind shear on the spatial distribution of TC precipitation, as well as the eyewall contraction process during TC intensification. The research confirms previously published results on TC precipitation distributions in relation to wind shear direction and provides detailed distributions for each TC category and TS.

Summary: Nonlinear wave-wave interactions play a critical role in the evolution of wave spectra in tropical cyclones, transferring energy from wind-sea to remotely generated waves. The peak waves act in a parasitic manner, taking energy from wind-sea to sustain their growth. This study provides strong validation of the importance of nonlinear processes in wind-wave evolution.

Summary: During September 15-21, 2020, a highly intense medicane named Ianos formed over the warm Mediterranean Sea, causing significant damage and casualties in Greece. This paper investigates the genesis and evolution of Ianos using in situ observations, satellite measurements, and model analyses. The study highlights that Ianos was the most intense medicane ever recorded in the Mediterranean and provides valuable insights into its structure and convective activity.

Summary: This study investigates the possible thermodynamic effects of global warming on landfalling typhoons and storm surges in South China, using the WRF and SLOSH models. The findings suggest that under a warmer climate, typhoon intensity, storm structure, precipitation, and storm surge may all change and have implications for South China and the Pearl River Delta region.

Summary: Understanding the spatial variation of tropical cyclone wind speed decay over the continental United States is crucial for hazard preparation inland. Tropical cyclones making landfall over the Gulf Coast tend to decay faster within the first 24 hours compared to those making landfall over the Atlantic East Coast. The presence of spatial variations in wind speed decay raises questions about the accuracy of a uniform wind decay model.

Summary: The interaction between Typhoon Nepartak and the upper-tropospheric cold low is simulated to understand the impact of the cold low on tropical cyclones. An experiment without the cold low is performed to highlight its quantitative impacts. Sensitivity experiments are carried out to investigate different configurations leading to various interactions. The study shows that the interaction between a tropical cyclone and the cold low is associated with a more axisymmetric inner-core structure and earlier rapid intensification.

Summary: The study modified a simple energetically based dynamical system model of tropical cyclone intensification to account for the observed dependence of the intensification rate on the storm intensity. According to the modified model, the intensification potential and the weakening rate due to surface friction beneath the eyewall control the intensification rate of the tropical cyclone.
