AERO TECHNOLOGY QUIZ

Q2:  

Dry weather lowers aerodynamic drag
a) True   b) False

False. 
Humidity is actually helpful.  Water molecules are lighter than air molecules.  As humidity goes up, the density of air goes down and aero drag goes down.  In trying to set time trial records wetter air creates lower drag and faster times.  This is one reason (along with calmer winds) why an early start while the day is breaking and dew is in the air may help your time.  Unfortunately humidity (with heat) also effects rider performance by increasing the potential heat overload of the rider.  This effect is also one reason why aero testing requires very very careful control of humidity.
