I came across an online article about "cloudburst". I would like to share some of the key points here.
The article said cloudburst is a phenomenon that is pouring rapidly in limited area for very short time. Honestly, I have never heard the phenomenon before, but I thought it was similar to liner rainbands. The prefecture I have lived faced the natural disaster in 2014. Many houses got completely washed out and many people were killed by the debris flow. That was why I never forget the phenomenon "Liner Rainbands". However, they have different features such as the following,
Liner rainbands Cloudburst
Duration for hours for 30 minutes to an hour
Area dozens of kilometers to hundreds a few kilometers to dozens
Rainfall hundreds of milimeters 100 milimeters
The affected area size is different, but the houses and roads in those area will take heavy damage such as houses collapsed and roads are flooded. In case of liner rainband, lots of thunderheads spreads belt-like and have stayed the same location for hours while it has been raining there. On the other hand, one thunderhead causes torrential rain in limited area and I guess it might be similar to a sudden downpour called the "Guerrilla Rainstorm" in Japan. Cloudburst often occurs in areas with a monsoon climate and in mountainous areas. That's why cloudbursts are observed in the foothills of the Himalayas. Japan is also strong affected by a monsoon climate and it often brings the rainy season, typhoon and torrential rain to Japan. So, I'm worried about whether the phenomenon happens in Japan as well. Actually, two typhoons have been moving across the country and they were wreaking havoc in some regions. I really hope the typhoon diminishes in strength as soon as possible.
