Simulations of the Central American Monsoon in a Pair of Regional Climate Simulations By Justin Gonzalez Description: In this talk, there will be a focus on differences in simulations of the Central American Monsoon between two 15-year regional climate models, which differ in their adopted cumulus parameterization schemes. Since the regional climate model is a coupled ocean-atmosphere model, discussion will include both atmospheric and oceanic variables. Discussion will also include validation of some of these variables with corresponding observations. The changing annual cycle of SST By Fucheng Yang Description: In recent decades, many research efforts focused on global climate change, multidecadal, decadal, interannual variability, and the increasing extreme events of sea surface temperature. In contrast, the continuous evolution of the reference frame, the annual cycle of SST used to quantify the aforementioned variability and changes, has long been overlooked, resulting in difficulties in understanding the underlying physical mechanisms responsible for these variability and changes. In this study, we strive to bridge this gap on the phase changes in SST annual cycle. By devising a running correlation-based method, we can now quantify the non-sinusoidal shape of the evolving SST annual cycle, such as the advancing or delaying of summer and winter peaking times. It is revealed that the varying phases of summer or winter are more closely linked to multidecadal SST variability than to long-term climate change. Both the systematic shift of the phase and alterations in the annual cycle shape contribute to the phase changes, which explain 0.4~1.0 ?C of monthly SST anomaly with respect to the climatological annual cycle in a multidecadal timescale. Furthermore, it is evident that the SST phases in historical simulations are not well captured and exhibit stronger variation compared with observation. Seasonal and long-term variability of the volume transport across the Yucatan Channel By Bhavya Mamnani Description: The Loop Current (LC) is part of the North Atlantic western boundary current and plays an important role in transporting heat from the equator to the poles, with impacts on climate. The LC has an irregular behavior: it detaches large, warm, fast-rotating eddies that can impact oil and gas operations, navigation, and marine life. Thus, changes in short- and long-term transport affect the detachment of the eddies and the global large-scale ocean circulation, respectively. This study explores the seasonal and long-term variability of volume transport across the Yucatan Channel. It focuses on analyzing ocean currents variability, specifically the volume transport variability at the Yucatan Channel from 1994 to 2017, using output data from the global, ~8-km, Hybrid Coordinate Ocean Model (HYCOM) simulation. We found that volume transport peaks in July-August with an average transport of around 28 Sv. This result agrees with the transport from the mooring array of Candela et al. (2019). For long-term variability, we find that the transport decreased on average from ~28 Sv in 1994 to ~25 Sv in 2006, then increased to ~27 Sv in 2017. Throughout this 6-month internship experience, I learned how to perform mathematical calculations through Matlab coding as well as gain a deep understanding of ocean circulation, in particular in the Gulf of Mexico, and its impact on marine life and the transport variability in the Yucatan Channel.

Mesoscale current feedback: Consequences for ocean dynamics and sea surface wave generation By Marco Larra?aga Description: The feedback of surface oceanic currents to the atmosphere has been shown to correct persistent biases in representing mesoscale eddies and western boundary currents by providing a clear energy sink from oceanic eddies to the atmosphere. However, its impact on regional ocean dynamics has not been widely studied. The Gulf of Mexico, characterized by the emblematic Loop Current and significant mesoscale activity, is an ideal region to investigate the importance of current feedback in modulating ocean dynamics. To address this, we use a set of two 24-year ocean-atmosphere eddy-rich coupled simulations, one incorporating the current feedback and the other without it. By damping mesoscale activity by about 20%, the current feedback increases the Loop Current extension and plays a key role in determining the periodicity and spatial occurrence of Loop Current eddy reattachments and separations, as well as the properties of the eddies. Regarding the interaction between sea surface waves and mesoscale eddies, studies have highlighted that mesoscale eddies refract remotely generated waves (swell) and produce negative (positive) significant wave height anomalies when waves and currents have the same (opposite) directions, with dominant occurrence of negative anomalies. However, we use observations from the Chinese-French Oceanography Satellite (CFOSAT) to show that the current feedback to the atmosphere indirectly affects the generation of sea surface waves. This feedback induces positive (negative) anomalies in wind stress over eddy regions where currents oppose (align) the wind direction. Consequently, this results in positive (negative) anomalies in the significant wave height of locally generated waves, with a dominant occurrence of positive anomalies. Additionally, our results show that stronger eddies produce stronger significant wave height anomalies. -------------- next part -------------- An HTML attachment was scrubbed...
