Summary: Previous studies have focused on intense tropical cyclones (TCs) in the central-southeastern western North Pacific. However, the modulators for weak TCs (WTCs) are not well understood. This research highlights the potential impact of the early spring North Atlantic tripole sea surface temperature anomaly on WTC frequency and develops a physical-based empirical model to predict WTC frequency.

Summary: This study highlights the significant influences of tropical transbasin variability (TBV) and ENSO on tropical cyclones in the western North Pacific, eastern North Pacific, and North Atlantic Ocean basins. The modulation of TC counts varies in each basin due to different effects of TBV and ENSO, with low-level relative vorticity and large-scale factors playing important roles in regulating TC frequency.

Summary: The study identifies an antiphase decadal variation in tropical cyclone (TC) genesis between the western North Pacific (WNP) and North Atlantic (NA) basins. This transbasin connection is triggered by the Atlantic multidecadal oscillation (AMO) and involves a subtropical east-west relay teleconnection. During a negative AMO phase, TC genesis is suppressed in the North Atlantic but enhanced in the western North Pacific due to changes in atmospheric and oceanic circulation patterns.

Summary: This study specifically investigates the response of Sargassum aggregations to high wind events, particularly tropical cyclones. The results show a significant decrease in Sargassum coverage under tropical cyclone trajectories, indicating their role in the seasonal decay of Sargassum biomass. The sinking of Sargassum towards the deep ocean is associated with this decrease.

Summary: This study investigates the Gulf Stream (GS) sea surface temperature (SST) anomalies associated with the extratropical transition (ET) of tropical cyclones (TCs) in the North Atlantic. The findings suggest that TCs that begin the ET process but do not complete it have warmer GS SSTs and weaker large- and fine-scale SST gradients compared to TCs that do complete the ET process. The analysis also shows that the fine-scale GS SST gradient anomalies are related to atmospheric processes, but they are different from the anomalies typically associated with the onset of ET.

Summary: This study investigates the relationship between extratropical transition (ET) of tropical cyclones (TCs) and Gulf Stream (GS) sea surface temperature (SST) anomalies in the North Atlantic. The results show that TCs that begin but do not complete the ET process have warmer GS SSTs and weaker large- and fine-scale SST gradients compared with TCs that do complete the process. These findings suggest that knowledge of the fine-scale GS SST gradient prior to a TC's arrival may provide additional information about the likelihood of completing ET.

Summary: The warming of the eastern Pacific strongly influences the future changes in Atlantic hurricanes, particularly the effect of El Nino. The changes include the formation regions of hurricanes and the intensity of the El Nino/La Nina signal.

Summary: The frequency characteristics of northward-moving tropical cyclones (NTCs) in the western North Pacific (WNP) are analyzed, and the possible combined effect of El Niño-Southern Oscillation (ENSO) and the North Atlantic tripole (NAT) sea surface temperature anomaly (SSTA) is investigated. The results show that the NTC frequency in summer exhibits interannual and decadal variations. The NAT modulates the relationship between ENSO and NTCs. During positive NAT phases, the effect of ENSO on NTCs is clear, while during negative NAT phases, only El Niño has an effect on the NTC frequency.

Summary: Using 42 years of reanalysis data, this study examines the regional and storm-relative characteristics of three different intensification groups of Atlantic tropical cyclones. The results show distinct probability density functions for vertical wind shear, sea surface temperature (SST), and radius of maximum winds (RMW) among these groups. The study also identifies the best predictors for different regions, suggesting the need for further investigation due to variability across regions, periods, and variables.

Summary: The connection between the North Tropical Atlantic (NTA) sea surface temperature (SST) anomalies and El Nino-Southern Oscillation (ENSO) events varies considerably over multidecadal timescales and is mainly controlled by the multidecadal variability of the North Atlantic Oscillation (NAO). During the positive phase of the NAO, the NTA impact on ENSO is amplified due to strengthening of precipitation over the equatorial Atlantic and enhancement of the persistence of NTA SST anomalies.

Summary: The El Nino-Southern Oscillation (ENSO) influences the sea surface temperatures in the North Tropical Atlantic, but studies suggest that ENSO drives climate variations in the Atlantic and not the other way around.

Summary: This study analyzed seasonal forecasting models from five European modeling centers to study tropical cyclones over the western North Pacific and North Atlantic basins. The models were able to capture the observed seasonal cycle of cyclone frequencies, but there were large differences in numbers and spatial track densities. While predictions for the western North Pacific basin were often unreliable, most models provided reliable predictions for the North Atlantic basin and were skillful in predicting interannual cyclone variability in a region covering the Caribbean and North American coastline.

Summary: This study explores the combined impact of sea surface temperature (SST) and the North Atlantic subtropical high-pressure system (NASH) on the interannual variability of tropical cyclone (TC) genesis and landfalling. Different regions show variations in both genesis and landfalling, with SST primarily modulating the frequency of TCs formed near the West African coast and NASH affecting those originated in the Lesser Antilles arc. SST and NASH explain a significant portion of the variability in landfalling in certain regions, highlighting the complexity of atmospheric processes involved in TC genesis and landfalling.

Summary: Decade-long satellite observations show that different intensities and moving speeds of tropical cyclones result in varying sea surface salinity changes on their left and right sides, with the most intense storms causing salinification and being influenced by the vertical salinity gradient in the upper ocean and barrier layers.

Summary: The study found that float-pairs equilibrating on the same isopycnal stayed close together for longer periods, with relative dispersion and diffusivity increasing exponentially with time. For separations less than 6 km, the diffusivity dropped significantly below classical power laws, aligning more with estimates from dye dispersion studies.

Summary: The scarcity of wintertime observations of surface ocean carbon dioxide partial pressure (pCO(2)) creates uncertainty in the understanding of the regional carbon sink near the Gulf Stream. Recent observations from an Uncrewed Surface Vehicle (USV) show lower pCO(2) in the subtropical mode water formation region compared to the atmosphere by about 50 μatm. This undersaturation, combined with strong wintertime winds, results in rapid ocean uptake of CO2.

Summary: The Gulf Stream is the only pathway for warm water to flow poleward in the subtropical North Atlantic, known as the Atlantic Meridional Overturning Circulation (AMOC). Using data collected since the 1930s, the upper-ocean transport between the U.S. Continental Slope and Bermuda, as well as Africa, was estimated, excluding the recirculation gyres of the Gulf Stream. The transport has decreased over the years.

Summary: Research indicates a northward shift of the Gulf Stream towards the Tail of the Grand Banks on the Northwest Atlantic Shelf in 2008, disrupting the connectivity of the Labrador Current and potentially contributing to abrupt warming and an ecosystem shift a year later. Historical observations suggest similar events may have occurred in the 1970s.
