#5 Localized Torrential Rain
Localized torrential rain is occurring with greater frequency in Japan. Flash floods from the heavy rain not only cause rivers to overflow but threaten homes and human life. This kind of weather has been difficult to predict, given the short timeframe between the formation of cumulonimbus clouds and the onset of rain. Yet a new type of radar called "phased-array radar" and a simulation using a Japanese supercomputer have been developed to forecast local downpours 10 minutes in advance. In this episode, we'll take a closer look at how the latest technology is being used to forecast localized torrential rain and protect lives.
