Question

How is radar used to forecast weather?

It shows areas of high and low pressure.
It collects data in the upper atmosphere.
It collects weather data as part of a network around the country.
It locates and tracks storms, and follows the path of storm systems.

Answer 1

Radar is primarily used to forecast weather by **locating and tracking storms, and following the path of storm systems**. Weather radar, such as Doppler radar, emits radio waves that bounce off precipitation (like raindrops, snowflakes, or hail). By analyzing the returned signals, meteorologists can determine the location, intensity, and movement of precipitation, which helps them predict storm development and track the path of existing storms. This real-time data is crucial for issuing warnings and forecasts.

While radar can also be part of a larger weather data collection network, its most direct application in weather forecasting is in monitoring and tracking storms.
