(a) radar
(b) storm spotter reports
(c) information from the public
(d) Both (a) and (b) are correct, (c) is incorrect.
(e) (a), (b) and (c) are all correct

Answer 1

Tornado warnings are issued based on radar, storm spotter reports, and information from the public. All three sources are important for verifying conditions that may lead to a tornado.

Step-by-step explanation:

Forecasters base the issuance of a tornado warning on several sources of information. These include data from radar, storm spotter reports, and information from the public. Specifically, Doppler radar is utilized for detecting rotational patterns in weather systems, which can indicate the potential formation of a tornado.

Storm spotters provide on-the-ground verification of weather conditions that radar might indicate, and they can confirm an actual tornado sighting. Lastly, information from the public can also play a role in storm reporting, providing additional evidence to support the issuance of a tornado warning. Thus, the correct answer is (e), indicating that all three sources—radar, storm spotter reports, and public information—are considered when issuing a tornado warning.
