In most cyclone prediction models, sea surface temperature (SST) is the only oceanographic input, even though storms are known to be impacted by the thermal energy available through oceanic heat content, not just by SST alone. In the tropical Indian Ocean (TIO; 30 ° S -30 ° N, 30-120 ° E), there are no studies that examine the relationship between instantaneous cyclone intensity (CI) and SST as a function of time. Here, we explore that relationship using SST data from the Tropical Rainfall Measuring Mission Microwave Imager and CI data (maximum sustained winds) from the Joint Typhoon Warning Centre. We find that out of 75 TIO cyclones studied during 1998-2011, more than 50% of the cyclones have no significant correlation between CI and SST. The numbers having significant negative (positive) correlations are 31 (3), 13 (10), and 17 (14) with SST leading CI by one, two, and three days, respectively. These results demonstrate that SST is not a useful indicator of CI in the TIO.

The synoptic structure of Typhoon Tess (1953) over the tropical ocean is examined to verify the development of a tropical cyclone into a severe typhoon from the viewpoint of Namekawa's theory of main and secondary typhoons. A hypothesis on the life cycle of a tropical cyclone is presented in conclusion.

Accurate sea surface temperature (SST) datasets are critical to typhoon simulation/prediction, especially to the intensity forecast. In this study, four SST datasets were used to perform a series of experiments to examine the effects of different SST datasets and a cold SST feature on the simulation of typhoon Nangka (2015) using the Advanced Weather Research and Forecast model. Results show that the simulated typhoon intensity is very sensitive to the SST dataset used. The experiments with the SST dataset in which a cold SST feature to the south of the storm track was present/absent succeeded/failed to simulate the peak intensity and the subsequent rapid weakening of typhoon Nangka. Among the four datasets examined, only the SST dataset from the National Centers for Environmental Prediction Global Forecast System analysis captured the cold SST feature, which was likely induced by typhoon Chan‐Hom (2015) before the arrival of typhoon Nangka.

The response of the sea surface temperature(SST) to typhoons in the Western North Pacific Ocean was investigated using data from typhoon yearbook,NCEP and Remote Sensing Systems(RSS).Six typhoon factors and four SST factors were chosen to study the response.The results suggest that the influence of typhoons on the SST depends on the intensity of the typhoon.Among all the correlation coefficients between the SST and typhoon factors,the correlation coefficients between SST decrease and air pressure gradient and pressure difference were found to be the largest,while the correlation coefficient between SST decrease and typhoon translationspeed was found to be the smallest.As the sea surface cooling is also highly related to the upper ocean condition,the relationship between the upper ocean structure and sea surface cooling was discussed and the results indicate that the response decreased with the increase of water depth in areas deeper than 100 m;with the deepening of the mixed layer,the SST cooling decreased,but not monotonously.

In this study, a total of 29 typhoons occurring in the 2004 Pacific typhoon season are simulated using an axisymmetric 2-D typhoon model (2DTYM) and a regional 3-D typhoon model (3DTYM). 2DTYM is intended to estimate the axisymmetric typhoon structure and its intensity constrained by typhoon's environmental parameters. 3DTYM is developed to evaluate the full structure of a typhoon from the genesis stage to the decaying stage, considering important typhoon-ocean interactions. Comparisons of these results simulated by both the models indicate that 3DTYM is able to predict the realistic typhoon intensity more accurately than 2DTYM, because 3DTYM can capture the internal asymmetric structure in a typhoon, which is responsible for typhoon intensity change especially during the decaying stage.

Abstract The frequent typhoons in the northwest Pacific drive oceanic responses, for example, changes in sea surface temperature (SST) and chlorophyll‐a (Chl‐a). A composite analysis shows that SST (Chl‐a) around the typhoon center decreases (increases). The SST begins to decrease 3 days before the typhoon’s arrival and further decreases until 2 days following the typhoon’s passage. The Chl‐a increases rapidly after the typhoon’s arrival, and the maximum value is reached 3 days after the typhoon. Large oceanic responses are often associated with typhoons that have high wind speeds and slow translation speeds. From the perspective of the upper ocean structure, increasing changes in SST are identified with a shallower pre‐typhoon mixed layer depth (MLD). However, a significant dependence of the Chl‐a response on the pre‐typhoon MLD emerges only when the depth of typhoon‐induced mixing is greater than the pre‐typhoon MLD. This study helps to quantitatively describe typhoon‐induced changes with consideration of the determinant oceanic environment.

Abstract On 6 March 2010, Anita, the first subtropical cyclone observed over the South Atlantic Ocean, formed near the southeastern coast of Brazil, and during its life cycle, Anita almost acquired a tropical structure. The potential of Anita to undergo tropical transition in scenarios of increased sea surface temperature (SST) was investigated through a set of numerical sensitivity experiments. The results show that, if the SST had been 2°C warmer throughout Anita's life cycle, the system would have undergone tropical transition in its maturity stage; however, if the SST had increased only during Anita's quasi‐stationary period, the tropical transition completion would have occurred only with higher values of SST (6°C).

Using NOAA and MODIS (Terra & Aqua) satellites data, and mainly basing on 3×3 degree square as study area, the authors systematically analysis the effects of Sea Surface Temperature (SST) caused by 37 typhoons which passed by the Northwest Pacific Ocean from 2000 to 2008 and find: (1) In the Northwest Pacific Ocean area, the SST without typhoon is averagely 26.10°C, but the SST is averagely 22.90°C during typhoon happened. The SST averagely decreases 3.20°C with the drop rate of 11.55%, and the maximal fall of SST is 7.79°C by typhoon. At the same time, the sustaining time with low SST is usually 2~5 days, and the time mainly lies on the lingering time of typhoon in the sea areas. After typhoon, the SST comebacks to the normal level before typhoon had happened. This can be seen clearly from the change of the SST before and after typhoon SAOMAI and LEKIMA .(2) In the study area of typhoon SAOMAI and LEKIMA passed through, there are certain rightward bias of the distribution of the decrease of SST before and after typhoon. (3) The decrease of SST during typhoon is positive correlation with the wind speed and negative correlation with the moving speed of typhoon respectively and the correlation coefficient is less than 0.3, but it is better positive correlation with the weight of typhoon and the correlation coefficient rises to 0.47.In conclusion, the effect of SST by typhoon is notable, and based on remote sensing to study this effects is effective means.
