Japan weather radar

The weather radar Japan shows where it is currently raining or snowing. The radar map is updated every 5 minutes with a new radar observation. The different colours indicate the intensity of rainfall or snowfall. Light blue indicates drizzle, blue a medium intensity, and red and yellow indicate very strong precipitation, usually associated with thunderstorms. Current lightning strikes are marked with small orange dots on the map Europe only. Note that lightning is not shown on the forecast, as it cannot be predicted. Moreover, some countries do not operate a weather radar network, and in those countries satellite data is used to estimate rainfall, which is less accurate than a realtime weather radar. This so called precipitation nowcast is the most accurate precipitation forecast possible but the forecast horizon is limited to about an hour. Longer forecasts are not possible, as new precipitation cells are developing or existing ones are disappearing within a short time. Real weather is more complex than just the displacement of existing precipitation cells. The forecast works very well when weather fronts or large organized precipitation structures are moving regularly, without disappearing or being created.

Weather radar is used to observe precipitation raindrops and snowflakes within a radius of several hundred kilometers using radio waves microwaves emitted from a rotating antenna. The distance to precipitation can be determined from the time taken for waves to bounce back, and precipitation intensity can be gauged from the amplitude of the reflected waves radar echo. Information on wind radial velocity in precipitation areas can also be obtained based on the Doppler effect in relation to reflected radio waves. These transmit and receive horizontal and vertical waves simultaneously, and enable classification of cloud-borne precipitation types as well as precise determination of rain intensity. JMA has operated weather radars since , and currently runs a nationwide network of 20 units. The observation data collected are utilized in real-time monitoring for disaster prevention and in the generation of initial values for use in very-short-range forecasting. Radio waves travel in a straight line in air, and are unable to penetrate obstacles such as mountains. The curvature of the earth's surface also makes it difficult to observe precipitation at low altitudes, especially in areas far from radars. Accordingly, weather radars need to be located in high places such as on top of mountains or steel towers.
