Summary: This study quantifies the contributions of tropical sea surface temperature (SST) variations during the boreal warm season to the interannual-to-decadal variability in tropical cyclone genesis frequency (TCGF) over the Northern Hemisphere ocean basins. The study finds that the dominant SST modes affecting TCGF vary among different basins and are related to ENSO, GW, PMM, AMO, PDO, and AMM. These modes explain a portion of the variance in TCGF in the North Atlantic, northeast Pacific, and northwest Pacific Oceans.

Summary: The Atlantic Meridional Overturning Circulation (AMOC), a key component of the climate system, is projected to weaken during the 21st century due to increased atmospheric CO2 concentration. Observational evidence suggests that the weakening started in the late 19th century, earlier than previously thought, with the estimated weakening larger than shown in numerical simulations.

Summary: This study investigates the sea surface temperature (SST) changes caused by 96 tropical cyclones (TCs) in the northern Indian Ocean (NIO) over an 18-year period. It reveals that within a radius of 300 km from the TC center, SST decreases were observed at 86% of locations, with an average SST response of -0.46 degrees C and a maximum decrease of -2.07 degrees C. The most significant reduction in SST typically occurred two days after the passage of TCs, followed by a gradual recovery period exceeding 15 days for the SSTs to return to their initial values. Stronger and slower-moving TCs induced more substantial cooling effects.

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: Satellite remote sensing data spanning multiple years have been used in this study to investigate the climatological characteristics of sea surface salinity (SSS) response to tropical cyclones (TCs). The study found that TCs initially lead to a decrease in SSS due to precipitation, followed by a salinification largely driven by vertical ocean processes. Factors such as TC intensity, translation speed, and vertical stratification in different basins also significantly impact the salinity response during and after TC passage.

Summary: This study has developed a regional scale spatial statistical model to analyze the relationship between tropical cyclones (TCs) and sea surface temperature (SST) and tropical cyclone heat potential (TCHP) in the North Indian Ocean region. The study found that using a geographically weighted regression (GWR) method, the contribution of SST and TCHP to TC intensity can be determined, and the model has been validated.

Summary: This study revisited the possible reasons for the rapid weakening of tropical cyclones embedded in monsoon gyres over the western North Pacific, showing that lower SST and strong vertical wind shear in the eastern semicircle of a monsoon gyre are the main environmental factors contributing to the rapid weakening of TCs.

Summary: Using satellite measurements, it was found that TC Seroja caused strong upwelling and vertical mixing in the Savu Sea, leading to phytoplankton blooms and a decrease in sea surface temperatures. This resulted in an increase in chlorophyll-a concentrations and a cooling of the sea surface temperatures by up to 3 degrees C.

Summary: Using atmospheric simulations forced with observed sea surface temperatures, the study investigates the variability and predictability of tropical cyclone genesis frequency (TCGF) in the northwest Pacific. Results show that the model can reproduce the observed TCGF variability in certain sub-basin regions, but has limited skill in other regions. Above-normal TCGF is linked to enhanced relative SST.

Summary: This study investigates the influence of sea surface temperature (SST) anomalies on the rapid intensification of tropical cyclones. It finds that SST anomalies' size and magnitude, as well as their length scale and storm translation speed, play crucial roles in modulating the timing of rapid intensification onset.

Summary: This study investigates the interannual variations in seawater CO2 partial pressure in the northwestern subtropical Pacific Ocean during the months of August to October with frequent tropical cyclone events. It found that the variations in pCO2 were related to vertical mixing likely caused by TC activity, leading the region to transition from a CO2 source to a CO2 sink during the TC season. In the southern part of the study area, smaller pCO2 variations were observed, possibly due to deeper mixed layer depth and a more homogenous CO2 profile in the tropical region.

Summary: The relationship between sea surface temperature (SST) and tropical cyclone (TC) intensity change is influenced by the current TC intensity. The study identified a threshold SST (TSST) that affects TC intensity, with TCs intensifying or weakening depending on whether SST is higher or lower than TSST. A formula was developed to quantify TC intensity change using SST and current TC intensity, which replicated 99.46% of observed TC intensity changes, providing a potential alternative to linear regression models for improving intensity forecasts.
