säätutkiin

Säätutki is the Finnish term for weather radar. These systems are crucial meteorological instruments used to detect precipitation, estimate its intensity, and determine its motion. Weather radar works by emitting microwave pulses into the atmosphere and then listening for the reflected signals. The characteristics of these reflected signals, such as their strength and frequency shift, provide information about the size, density, and movement of precipitation particles like rain, snow, and hail.

Finnish meteorological services operate a network of weather radars across the country to provide real-time weather information. This data is vital for forecasting, issuing severe weather warnings, and for aviation safety. The information gathered by säätutki can be visualized as a radar map, showing areas of precipitation and their intensity, often color-coded for clarity. These maps are widely accessible to the public through various weather websites and applications, allowing individuals to monitor current weather conditions and anticipate upcoming changes. The development and deployment of weather radar technology have significantly improved our ability to understand and predict atmospheric phenomena.
