“Torrential rain completely caught.” That’s the promise of the Tokyo Area Rain Gauge System. It stands as a testament to Tokyo’s dedication to precision and real-time awareness.
The Tokyo Area Rain Gauge System is not just one instrument. It is a network. This system uses radar technology to observe rainfall intensity. It also notes the locality of rain. The system harnesses electromagnetic waves. These waves change when they hit an object. The changes reflect back to the source.
This rain system gives a wide-range view. It covers the area in and around Tokyo. The area spans approximately 190km east to west. It also reaches about 120km south to north. You can see precipitation at a glance. Note that this excludes snow.
Precise measurement is a key feature. The resolution meshes are square. Side lengths measure either 150m or 250m. The measurement depends on the distance from radar stations. This makes it possible to catch torrential rain completely.
Real-time monitoring is another advantage. Data updates happen quickly. You can grasp the change of rain without delay. This is crucial for managing potential flooding and for daily life.
The Tokyo Area Rain Gauge System uses sophisticated technology. Radar beams reflect off raindrops. The system filters out unwanted reflections. Mountains can cause these unwanted reflections. It isolates reflections from rainfall only. A computer calculates the intensity and distribution. This data is processed for use in various applications.
Tokyo Amesh, as it is also known, includes two radar sites. These are the Port Radar and Inagi Radar. Ground rain gauges add to the system’s accuracy. These gauges belong to the Sewerage Bureau and Construction Bureau. All components form the radar rain gauge system.
The central processing unit sends rainfall intensity data. This data is received. It displays rainfall conditions. The display covers the radar observation range. General weather information is also shown. Tokyo Amesh provides a user-friendly interface. It presents various weather data with high precision.
The system refines weather data received from meteorological companies. It displays this information graphically. This makes it easy to understand. It helps residents and authorities prepare for changing weather. The Tokyo Area Rain Gauge System keeps Tokyo prepared. It helps manage the city’s resources effectively.
