# Trivia Testers : You Mean We’re Not In Kansas Anymore?

Question: During the month of March, in which of these states are you most likely to see a tornado?

1. Oregon
2. Alabama
3. Ohio
4. Kansas

Answer: B, Alabama. Actually, different parts of the US have their own peak seasons for tornadoes. In the first three months of the year in fact, tornadoes are most common in the Southeast. This is where there are more confrontations between cold and warm air masses, and that is what helps to create the thunderstorms that produce tornadoes!

Subject: Dippy Compasses

Question: The earth’s magnetic field runs parallel to the earth’s surface at the equator, but in northerly latitudes it dips downward ‘into’ the earth. This is what is responsible for the familiar turning errors, introduced in ground school. To a very rough first approximation, what are the magnetic dip angles at 30 degrees and 60 degrees North? (The field is not radially symmetrical about the poles, and so there is also a longitudinal influence.)

1. one and a half degrees down at 30N, four degrees down at 60N
2. three degrees down at 30N, eight degrees down at 60N
3. 12 degrees down at 30N, 18 degrees down at 60N
4. 50 degrees down at 30N, 75 degrees down at 60N

Answer: D, believe it or not. (The approximate formula is tan(d) = 2 tan L, where d = dip angle and L = latitude.)

Question: True or false: It is possible for an amateur radio operator to reserve his or her ham radio call sign for the tail number of their aircraft.
