First-authored paper is published in Geophysical Research Letters

The 11th first-authored paper “Characteristics of Low-Frequency Pulses Associated With Downward Terrestrial Gamma-Ray Flashes” was published in Geophysical Research Letters.https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2021GL097348 In the GROWTH experiment at Kashiwazaki City, Niigata Prefecture and Kanazawa City, Ishikawa Prefecture, we detected terrestrial gamma-ray flashes (TGFs) that are concident with lightning discharges, in addition to minute-lasting gamma-ray glows emitted from thunderclouds. […]

Co-authored paper is publised in JGR Atmospheres

The paper “Atmospheric Electron Spatial Range Extended by Thundercloud Electric Field Below the Relativistic Runaway Electron Avalanche Threshold”, led by RIKEN’s post-doc researcher Gabriel Sousa Giniz (JSPS Foreign Research Fellow), is published in Journal of Geophysical Research: Atmospheres. In this paper, considering gamma-ray glows, we verify how electrons are accelerated by Monte Carlo simulation with […]

Oral presentation at AGU Fall Meeting

I made a presentation entitled “Low-frequency pulses associated with downward” at the “Energetic Radiation From Lightning and Thunderstorms I” session of the American Geophysical Union Fall Meeting 2021, December 13-17, 2021. By organizing the cases of Downward TGFs observed in Kanazawa City, Ishikawa Prefecture and Kashiwazaki City, Niigata Prefecture, and analyzing the LF waveform of […]

New career at Osaka University

In May 2021, I joined Ushio Group, Division of Electric, Electronic and Infocommunications Engineering, Graduate School of Engineering, Osaka University as an assistant professor. In addition to high-energy atmospheric physics, I’ll develop an innovative weather radar system to identify, investigate, and predict severe weather phenomena. My office then moved from Tokyo to Osaka, the second […]

A first-author paper published in Geophysical Research Letters.

Our paper entitled “Meteorological Aspects of Gamma-ray Glows in Winter Thunderstorms” has been published in Geophysical Research Letters. In this paper, gamma-ray glows detected at Kanazawa University were analyzed with data of an X-band weather radar. Gamma-ray glows were found to correspond to a convective echo region passing above the detector.

Two first-author papers published in JGR Atmospheres

Two first-author papers– Photonuclear Reactions in Lightning: 1. Verification and Modeling of Reaction and Propagation Processes– Photonuclear Reactions in Lightning: 2. Comparison Between Observation and Simulation Modelwere published in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union. The two papers were edited from a part of my doctoral dissertation and […]

My long stay in France starts

From September 15th, I stay at Laboratoire AstroParticule et Cosmologie, Université de Paris, Paris, France. With the launch of the lightning observation satellite Taranis, which I have been involved in the development, in November, we will carry out the initial operation and in-orbit calibration.
