Japan will test rainfall and tornado prediction technology 30 minutes before the start

The system will deal with the prediction of the so-called "partisan showers" - precipitation, which are formed due to

water vapor and which are quite difficult to predict. For example, existing meteorological systems do not cope with this task.

The system is developed by the NationalThe Institute of Information and Communication Technology of Japan (NICT), along with public and private companies. It is planned that it will be deployed for the Olympics in Tokyo in 2020.

Multi-parameter meteorological radar withA phased array antenna (MP-PAWR) can predict rain showers and tornadoes 20-30 minutes before they occur. This will allow a flat antenna, which radiates radio waves in a wider range than the rotating antenna in the form of a bowl, used in traditional radar. It is a combination of MP radar, which allows you to observe the size of raindrops, and a phased-array radar, which provides a three-dimensional scan of the cloud structure in about 30 seconds.

For the first time in history, Chinese engineerslaunched from the unmanned submersible ship rocket probe for meteorological observations. The device will allow to monitor the atmospheric phenomena in areas beyond the reach of other probes.
