The speed of the wave stays same but the frequency change due to motion.
The average forward speed of a hurricane is 10-15 mph
The shape of the wing and the forward speed generates lift and the aircraft rises.
The average tornado moves at about 30 miles per hour.
By tilting the main rotor forward or backward.

it moves faster
This is an example of the property of inertia. It is a body of mass' tendency to resist change in motion. The man was in motion at the speed of the bus. When the bus slows, the mass of the man resists change in motion and continues to move forward. It's basically the rebelliousness of matter.
It moves forward at the same speed the car is traveling. It will fall to the ground in short order.
Acceleration is the change of speed upward. Velocity is any speed, in a fixed direction. So the diference, is that in speed; the direction can change, but the speed remain constant. Only if it moves faster or slower dose the speed change. So in velocity, if the speed, or the direction change, then the velocity changes.
If the velocity changes, the speed may, or may not, change. The velocity can be thought of as having two components: a speed, and a direction. It is possible to change only the direction, for example, when an object moves in a circle at a constant speed. In this case, the velocity changes, but the speed does not.
The speed of a wave is a property of the medium, changing the speed would need a change in the medium itself. If the medium doesn't change as a wave moves, the wave speed is steady. Formula: Speed = distance divided by time
As long as it remains in the vacuum in the vacuum, the speed of the light doesn't change at all.
