Introduction of Research
We study various meteorological phenomena, primarily lightning discharges and rainfall, from an observational perspective. In particular, we are working on observing torrential rain and cumulonimbus clouds using phased array weather radar, observing high-energy atmospheric phenomena emitted from thunderclouds and lightning discharges using a combination of radio waves, visible light, and radiation, and observing the upper atmosphere using muons, which are high-energy particles coming down from space. We aim to reveal phenomena that were previously invisible with cutting-edge observation methods, and at the same time, we are developing observation methods themselves, striving to advance meteorology through both instrument development and observation.
Representative Achievements
| Academic degree | Ph.D. in Physics |
| Self Introduction | I'm from Maniwa City, Okayama Prefecture. While Okayama is known as the "Land of Sunshine," the northern part of the prefecture is an exception, as there are ski resorts within the city. I've lived in Tokyo, Paris, and Osaka before finally settling in Sapporo. I used to be interested in elementary particles, atomic nuclei, and the universe, but my research topic shifted to the more familiar yet dynamic subject of weather. My hobbies are piano and photography, but I rarely have time for the former. At the very least, I hope to encounter as many of Hokkaido's beautiful landscapes as possible. |
