On July 9, 2014, we have visited Professor Ushio at the Osaka University Suita Campus and had a wonderful opportunity to look at the Phased Array Weather Radar (top photo). Professor Ushio was very kind and stopped the radar operation for us to enter the radar dome to look inside. There was a large flat plate barely fitting in the dome. It rotated quite fast, 10 seconds per round. Once Professor Ushio turned on the radar again, we could find some echoes around 50-60 km away, near the maximum range of the radar. The radar image was refreshed amazingly fast, only every 30 seconds.
We are working very hard on using the data from this particular new type of radar most effectively and efficiently, and try to improve the very short-range weather forecasts through "Big Data Assimilation" innovations. Observing the actual radar that we are working on really helped enhance our motivation. What Professor Ushio was saying on TV "Yume-no-tobira" (meaning "Door to Dream") echoed over in our mind: "we just work hard, faithfully and honestly."
