Air raid sirens are a sort of tube thing that has a handle on the side.You turn the handle so that an enormous whiring sound echos over the town.It stands on a sort of tripod and is usaly black or dark green to blend in with the night.For an image of an Air Raid Siren,go on Google images and type in 'Air Raid Siren from world war 2'. There is a small canister-like object (stator) and something inside it (chopper). Both have large holes. A motor or crank spins the chopper. Air is forces out of the holes in the stator, making the sound. The louder the siren, the larger. Some are as big as a CRANE. The Sirens have MANY, MANY different designs from horn, chopper assembly, then rotator, then blower, others 2 sets of choppers and the motor in the middle. You can just type Air Raid Sirens from a search and go to Images. You'll see.

An electric siren works by connecting the positive and negotive wires to the correct places. The current flows through and powers a small speaker. An air raid siren works by having an impellor and a cover. The cover has holes and as the impellor spins, it pushes out air and causes a deep and loud sound.
That air raid siren you hear also serves as a tornado warning. The shrieking winds of the tornado will sound like a freight train passing by.
