Question

what role does the automated surface observing system (asos) play in weather forecasting?
○ it is a kind of weather balloon.
○ it is a system of radar stations used to track storms.
○ it is the nation’s primary weather observing network.
○ it provides weather reports much like the national weather service.

Explanation:

The Automated Surface Observing System (ASOS) is mainly for surface weather observations, but radar systems (like NEXRAD, though ASOS has some related aspects in tracking storm - relevant data). Option A is wrong as ASOS isn't a weather balloon. Option C: ASOS is a key weather observing network but "private" is incorrect (it's a cooperative network including public entities). Option D: ASOS is for observing, not forecasting like the National Weather Service (NWS) does. So the most appropriate is B as radar - related systems (ASOS has components that help in tracking storm - related weather elements) are used to track storms.

Answer:

B. It is a system of radar stations used to track storms.
