What is albedo?
The ratio of light intensity an object reflects to the light it gets from the sun.

Why do urban areas experience lower wind speeds?
Tall buildings cause friction on the wind slowing it down.

What are vortices?
The tall buildings cause turbulence, where the wind hits the front of the building, causing some to be deflected down towards the ground in different directions.
Once at ground level, winds often collide with other buildings causing a swirling motion, kno
