The local authorities in Bergen, Norway (2nd largest city of Norway)
have banned half of the cars from the inner part of Bergen tomorrow
and coming days.
Bergen have had the worst air condition in Europe this week.
Other measures gave little effect on the quality of the air, so
this drastic measue was introduced.
The reason for the low quality air is the very cold temperatures from
a constant high pressure system above southern Norway in the last weeks.
This has brought record low temperatures, and as Bergen is a large city
bounded
in most directions by high mountains ("syv byfjell"), the denser cold air
flows
into the low-lying areas while the warm air above traps the pollution
from cars, home heathing and industry with an effective lid.

(in norwegian).
The irony this is a bit late as fairly strong winds will occur starting from
tomorrow. Better late than ever...?
