Biography

My current research involves the use of climate model outputs to analyze southern hemispheric circulations, climate indices, and sea-ice distributions. Specifically, I am directing my focus towards assessing the variability of southern hemispheric large-scale atmospheric circulations and their influence on sea-ice distributions, with particular attention to sea-ice thickness. Despite its significance in understanding polar climate and ecosystem, sea-ice thickness remains the least studied sea-ice parameter. By studying it in the model world, we can expand our knowledge on sea-ice changes in both the present and future, while gaining a better insight into the complex thermodynamics and dynamics that shape this parameter. Additionally, establishing a relationship between sea-ice thickness and climate variabilities can aid in comprehending climate extremes and their impact on overall sea-ice changes in the polar regions.
