work in progress (they all are...)

1. Merry Christmas Frenchie

2. Heat rises, but the surface matters.
Roughness and angle

3. With a central high point and gradual
surface angle, air flow is fairly smooth

4. Urban expansion is not truly radial, it
happens in patches.

5. This affects where the center of the
heat island is.

6. Heat builds up when there is not a
smooth supply of air to the area.
Poorly planned convection patterns
can eddy or be erratic.

7. As a city grows, it tends to more
closely resemble radial growth over
time, shifting the center but not far
away.

8. Sometimes a building isn’t possible
with existing technology and budget,
but a tower or statue is, like the Eiffel
Tower.
