“…Food web dynamics significantly correlated with summer environmental trends and this is consistent with other studies showing strong summer environmental trends (Lovenduski and Gruber, 2005;Swart and Fyfe, 2012;Panassa et al, 2018;Fonseca and Martín-Torres, 2019;Meredith et al, 2019). Stronger correlations during summer between our model output and environmental data could be a result of the trends used to calibrate the model.…”

Understanding the impacts of climate and fishing on marine systems is important for ecosystem-based management in the Southern Ocean, but can be difficult to evaluate due to patchy data in space and time. We developed the first time-dynamic food web model for the Kerguelen Plateau using Ecopath with Ecosim to explore likely drivers of change in this relatively data-poor region. The Kerguelen Plateau is located at the centre of intersecting frontal systems and is inhabited by one of the largest populations of the commercially important Patagonian toothfish. We used this model to evaluate the environmental and human drivers of food web dynamics in the region by calibrating it with French and Australian fisheries data from 1997-2018 and biomass data for the period 1986-2018. Fishing was not identified as a driver of food web dynamics within this model, which could indicate that current management strategies are sustainable. A correlation analysis with environmental parameters likely to drive food web dynamics (sea surface temperature, zonal wind, Southern Annular Mode and chlorophyll a concentration) highlighted cool sea surface temperature, higher zonal wind speeds and negative phases of the Southern Annular Mode as important drivers of change, particularly during the summer. As the Southern Ocean is predicted to warm and winds are expected to intensify under future climate change, our study illustrates the importance of considering environmental change in ecosystem management.

“…Predecessors have achieved good results in using WRF model to carry out research (Fonseca and Martín-Torres 2019), so this paper also adopt WRF model to simulate. By comparing the typhoon centre position and typhoon intensity of the WRF model with the actual CMA typhoon data at each time point, we found that the simulation results match well with the actual time point of intensity change and maximum wind speed (12:00 UTC on October 27 th ).…”

To investigate the stratosphere-troposphere exchange (STE) process induced by the gravity waves caused by typhoon “Molave” (2020) in the upper troposphere and lower stratosphere region, we analyzed the ERA5 reanalysis data provided by European Centre for Medium-Range Weather Forecasts and the tropical meteorological optimal path dataset from China Meteorological Administration. We also adopted the mesoscale forecast model Weather Research and Forecasting model, V4.3, for numerical simulation. Most of the study is about typhoon-induced STE and typhoon-induced gravity waves, so our research will provide information for the study of STE caused by typhoon-induced gravity wave breaking. Our analysis shows that in most of the time, the gravity wave signal of typhoon “Molave” appeared below the tropopause and on the east side of the typhoon center (10°N-20°N, 110°E-120°E), it was stronger than that on the west side, suggesting an eastward tilted structure with height increase. When the gravity waves in the UTLS region (100°E-108°E) which on the west side of the typhoon center broke up, it produced strong turbulent, resulting in stratosphere-troposphere exchange. At this time, $\stackrel{-}{PVW}$, the average potential vorticity vertical flux, increased with the average ozone mass mixing ratio. The gravity wave events and STE process simulated by the WRF model are basically consistent with the results of ERA5 reanalysis data, but the time of gravity wave breaking is different. This study indicates that the distribution of typhoon-induced gravity waves is related to the background wind field, and after it is broken, it will generate turbulent mixing, causing the STE.
