what is the relationship between air pollution patterns and air movements in the sydney area?

check your stream water at above source soil runoff area,and compare periodic outfall testing in areas where there is an irregular out flow.you will discover a number of virulent bacteria changes with severe pollution.this is part of my study into the current worldwide MRSA infection cycles

Increased traffic, which causes smog. You can also consider noise pollution, from the cars and people coming and going, and any trash or recyclables that are not handled correctly.

The calculated number is placed within the appropriate index range and the accompanying descriptor word is used to report that day's pollution level."\n\nhttp://www.epa.gov/air/criteria.html\nThe link above is a site that gives more info about the NAAQS

air naturally comes from high pressure fronts to low pressure fronts\n\nalso if you look at weather maps those wierd looking squiggly lines \nthe closer together they are the higher wind speed you'll have

I am in Woodland (Sacramento) California. I am going to Sydney this summer (your winter) and I hope that it will be nice there.

A lot of wind current is caused by temperature differentials between two or more areas.  The earth's rotation is also responsible for currents and jet streams.  I had a porfessor tell me that the same wind that is blowing now is the same wind that has been blowing for 4 billion years.

You are referring to "Chem-trails." Supposedly the government or some shadow agency is testing various chemicals on the environment or American citizens (depend on which "investigator" you talk to). Chem-trails are usually distinguished by heavy air traffic in an area, often times forming a criss-cross patterns. Such reports are also often accompanied by unexplained sickness or asthma. On occasion, someone also claims that the chemicals will produce odd substances on the ground the next morning (sometimes described as a crystalline structure, other times spider-webby).\n\nYour pictures, however, only show one trail (which appears to be a con-trail) and some pretty clouds (probably the result of pollution, though other natural explanations are available as well). In all likelihood, your pictures are nothing more than scenic.\n\nAs to if chem-trails are real, I've never seen a reliable source report them, nor have I ever seen any compelling evidence put forth.

What i guess you should be looking for will be atmospheric sciences or u could scratch it down to atmospheric physics. There are thousands of articles and publications on the latter. Check your local public library or bookstore.

Arguably the principal source of air pollutants worldwide is motor vehicle emissions. While the U.S. has adopted stringent emissions controls, the EU has not been as assertive in this field; nevertheless, the U.S. is still the leading contributor to mobile source air emissions merely due to the very high number of vehicle miles travelled per capita. Underdeveloped countries lag severely in emission controls on motor vehicles, especially roadway vehicles, and on a per vehicle mile travelled basis produce many times the emissions of the U.S fleet.\n\nThe U.S., Russia, China and Japan lead the world in air pollution emissions; Canada is the number two country if measured in emissions per capita.\n\nPrincipal stationary pollution sources include chemical plants, coal-fired power plants, oil refineries, nuclear waste disposal activity, incinerators, large animal farms, PVC factories, metals production factories, plastics factories, and other heavy industry.\n\nSome of the more common soil contaminants are chlorinated hydrocarbons (CFH), heavy metals such as lead, which is found in lead paint and until recently in gasoline, MTBE, cadmium, which is found in rechargeable batteries, chromium, zinc, arsenic and benzene. Ordinary municipal landfills are the source of many chemical substances entering the soil environment (and often groundwater), emanating from the wide variety of refuse accepted, especially substances illegally discarded there, or from pre-1970 landfill that may have been subject to little control in the U.S. or EU.\n\nPollution can be the consequence of a natural disaster. For example hurricanes often involve water contamination from sewage, and petrochemical spills from ruptured boats or automobiles. Larger scale and environmental damage is not uncommon when coastal oil rigs or refineries are involved. Some sources of pollution, such as nuclear power plants or oil tankers, can produce widespread and potentially hazardous releases when accidents occur.\n\nIn the case of noise pollution the dominant source class is the motor vehicle, producing about ninety percent of all unwanted noise worldwide.

All the studies I have heard on this have been either negative or inconclusive.  Many years ago at University people were hypothesising about electronic 'smog' but the debate never really got anywhere.\n\nI can't rule out that the growth of electronic devices has created a higher level of this smog and that, since our synapses work on electrical signals, this can't be a problem.  I still await any conclusive research.

It is important because of the enviroment. The animals, the air quality all need to be very clean. If an area doesnt stay clean, the enviroment will become nasty
