Radars are instruments that were created by humans to detect objects, people, places, among others, through signals. Radars are devices used in different fields such as war, aviation, climatology, geography, among others. One of the best known is the Doppler radar, which is a climatological tool that is used to detect the intensity, size, quantity, and direction of rainfall. Likewise, rainfall is influenced by the direction and speed of the wind, data that can also be obtained using this tool. One of the purposes for which this object was created was the early detection of natural phenomena related to rains, and winds such as hurricanes, electric storms, hail, among others. Therefore, the two objects that scientists can obtain with a radar are C. Amount of rainfall, and D. Wind speed.
