Now I am studying the sea and sky, which fascinated me when I was a child, and I am very happy.



1.What kind of the research are you doing?

Does the ocean change the atmosphere? I am doing research to get the answer to this question.

The Earth we live on is covered with ocean and atmosphere, which interact with each other to form the Earth’s climate system. This is called the atmosphere-ocean interaction. This interaction has been going on since the birth of the ocean about 4 billion years ago. Until the 20th century, scientists have revealed the effects of the atmosphere on the ocean. However, the opposite, the impact of the ocean on the atmosphere, is still a mystery. I am trying to clarify which oceans affect the atmosphere at what time scale and how much, focusing on the world’s oceans, from observational data analysis and numerical simulations using the atmospheric model.

Understanding the influence of the ocean on the atmosphere is very important for considering today and tomorrow’s weather, seasonal forecasts such as hot summer and warm winter, and future climate such as 10 and 100 years ahead. How will the role of the ocean change in the climate system that is changing due to global warming? My dream is to get as close as possible to the “truth about the sea and sky”, which is still a mystery.

2.What is the reason for starting your study?

I grew up in a town in Shizuoka Prefecture, where the ocean was just a 30-minute bicycle ride away. I loved lying on the beach and looking at the sky, surrounded by the smell of the tide and the sound of the waves. I was especially fascinated by that moment when the sun was sinking into the horizon, luring the sea and sky into darkness. I entered Tohoku University without a specific goal, but after half a year, I was very surprised to learn that there is natural science in physics. Of course, I chose this natural science without hesitation. It was really an unexpected good match. Now I am studying the sea and sky, which fascinated me when I was a child, and I am very happy.

3.Message for prospective students

In Faculty of Science, all students and faculty members are doing science. What we get through science is “discovery”. No matter how trivial this discovery may be, it is the first “knowledge” of the 7 billion humans in 4.8 billion years of Earth’s history. Imagine knowledge and establish knowledge though the creation of knowledge. Then, the knowledge turns into the “knowledge” of many people. That is science. Doesn’t it make you excited to think about it? We welcome the challenge of young people trying to be at the frontier of knowledge.
