Atmospheric pollution may be worse in places with a dry climate because for example rain, it can disperse the pollution in an area, however a dry climate will have little wind, which means there is less chance for the pollution to be blown away and be dispersed. Moreover, dry climate meaning less rain, will mean that the pollution will cluster together and stay at the same place. In the day, the air particles rise up, but in the night the temperature drops, causing the air particles in the valleys to be trapped, because it is heavy. This is called temperature inversion.
(ii) Where are strategies for reducing traffic emissions likely to be more effective - in developed world cities like los angeles or in developing world cities like Cairo and Beijing?
Strategies for reducing traffic emission is likely to be more effective in developed world cities such as Los Angeles, because they have more money than the developing countries to come up with technology and methods to reduce traffic emissions. Los Angeles can spend more money on public transport and also catalytic converters in cars. However, it would be easier to reduce traffic emissions in developing cities like Cairo because there are less people therefore the people living there can be easily controlled and influenced.
question i would probably get you full marks but make sure you are treating the two questions separately - problems from lack of rain, and inversion layer are two separate issues
ReplyDeletepart ii is well done.
