Weather and Pollution
How is the east coast affected by the weather (and the
pollution) in L.A.? Does the pollution in L.A. "travel" to the east
A very small amount of pollution from the west coast
reaches the east coast. Most of it is rained or
snowed out of the air before it reaches the plains states.
However, a small part, which is mixed up into the
stratosphere may reach the east coast.
