How does weather affect smog levels?
145821
A temperature inversion will not allow air from the surface to mix with air above the surface. This leads to calm winds and the smog stays concentrated over the same area for prolonged periods. This is usually associated with a high pressure system. A low pressure system that moves into the area can cause surface winds to increase and mix the polluted air with cleaner air higher in the atmosphere and spread the pollution over a larger area. The lack of an inversion can also lead to mixing and spread the pollution vertically in the atmosphere. One can predict the beginning and ending of high pollution days by monitoring weather forecasts.

I suspect that what you mean is that the relative humidity is sometimes greater at night than it is during the daytime. This is because the air is warmer usually during the day, so it can hold more moisture.

Changes in air pressure and possibly humidity.  Your body turns into a barometer.

Geographic location and altitude of the air mass, also the proximity of large bodies of water. Water tends to have a moderating effect on temperature. Moisture content changes at altitude and lower temperatures as moisture is lost in the form of precipitation.\n\nFor example you have on a mountain peak several zones one of which is the zone of precipitation, the altitude at which precipitation is likely to occur. The second is the zone of accumulation which is the altitude at which accumulation of precipitated materials is likely to occur (snow line).

Asthmatics and others with respiratory problems should be especially careful as air pollution is expected to be high with ozone warnings.\n\nThe Department of Environmental Conservation will issue ozone warnings. Ozone is formed when emissions from vehicles and industry reacts with heat and sunlight. It is a major component of smog.\n\nHealth officials recommend limiting strenuous outdoor activity when ozone levels are highest, usually between noon and 6 p.m.\n\nThose most susceptible to ozone include the very young or old, and those with existing lung ailments.

In my opinion, weather is everything. People are creatures of leisure, we always strive to do something fun outdoors, and the only way we can do this is if the weather is good enough (sunny enough) to do so. Every-time someone looking forward to going on a trip, having a picnic, visiting friends and relatives, and to the simplest activity to do at home, mainly relies on a good sunny day to do it with. Weather affects us in so different ways that more accident happens when it is raining, cloudy days or prolonged overcast skies raise the feeling of depression, and in an adverse move to counteract depression, many individuals and couples tend to stay at home and do some simple chores, sleep more, or resort to some cozy romantic activities. Therefore, weather do play a big part on everybody's overall outlook into starting their day, and how it might end.\n~meow

Climate is affected by a number of sources such as where your location is to the equator, the earths rotation, etc. Long term changes are taking place very slowly due to human activities (gases, deforestation, soil erosion etc) and need to be addressed on a global level to prevent further changes. Increased gases in the atmosphere cause heating...and deforestation and decrease of plant life means that many of the carbons are not being used - so they continue to increase in the atmosphere causing changes. \nThere is no way to "stop" it, just slow it by us being more energy efficient, stop creating so much pollution...\nYou can somewhat effect microclimates - a local area that is changed because of large cities, large mountains etc - but not really hard to do intentionally - it's done over time as something builds up and disturbs the existing temp.\n\nWhew...that was a long one.

How scientific do you want it?\n\nBasically, air circulates the earth.\n\nThis air has different temperatures in different places.\n\nThe different temperatures cause different pressures of air masses.\n\nBecause of this air flows around air masses due to the pressure gradient between different masses.\n\nThis air flow drags air of even higher temperature differences into contact.\n\nDifferent air temperatures meet causing one to rise over the other, as this rising air goes up it cools and causes clouds (These areas where air masses join are the fronts on a weather map).\n\nThese clouds then produce rain.\n\nThat rain changes temperatures, more air masses are drawn into contact, and the cycle repeats.

Weather affects air pressure.  This affects man.  Some are sensitive to the change in air pressure and can result in headache and knee pain and more.

I have similar problem myself.  I have breathing difficulty when the weather change slightly, even more accurate than the weather forecast.\n\nThis is rather common, similar to a lot of immunological reaction, such as hay fever and asthma.  The immunological response in your body is suppose to fight the attack of any foreign infection.  However, sometime, some seemingly harmless particles such as dust or nut protein could trigger a massive reaction which results in fever, imflammation, swollen blood vessel and high blood pressure.

Why do people ask such questions?\n\nIf there is an obstacle to the flow of the air, of course it's gonna change the climate and temperatures because the air flow cannot go through mountains barriers, it will clash against it and part of it will go over it.\n\nBut the point is, if it was a cool air flow in hot summer ( happens sometimes but you'll have to ask another question on this subject), the sky will get all the cool air but because of the mountains barriers the lower part of the flow will not go through, that is how we get rain on hot days!

Pressure changes affect the wind.  Temperature change determines whether it will rain or snow.

The atmosphere modulates the amount of temperature change that can occur.  Clouds block some radiation from reaching the earth's surface during the day, and hold in heat escaping into space during night time.  The moon, lacking an atmosphere but orbiting at the same distance from the sun, experiences much larger temperature swings during the lunar day/night cycle.

wind has entirely everything to do with pressure, not so much temperature..but since temperature differences causes pressure differences, i'll let it slide\n\nWind always flows from High to Low...and as you see on weather maps, meterologists give these highs and lows numbers..corresponding to the pressure on a barometric scale\n\nso if you have a high pressure system of 31.15" of Mercury..and a low pressure of 28.45" of Hg then you have whats called a pressure gradient\n\nas this pressure gradient increases (the high gets higher and the low gets lower) the wind strength increases...\n\nSo the strength and direction of wind is created by the pressure gradient..but its also influenced by teh earths rotation..this is called the coriolis force...the fact of the matter is, is that the air is moving over a rotating surface..so in the Northern Hemisphere, the wind is seemingly deflected to the right..because the earth is spinning

Smog wasn't so bad, so it wasn't so hot.

Low pressure is related with storms\nHigh pressure is related with good weather\n\nThe way i understood is... that is a measure of air pressure\nif its sunny then all the air above is pushing down\n\nif there are storms there is water and stuff in the air taking up space therefore less air pushing down \n\ndoes that make sense

Interesting question.\nWe know from statistics that voter turnout is heavily influenced by the weather.\nAnd we know that God controls the weather. \n\nSpeaking to Pontius Pilate, Jesus said, \nJohn 19:11  "Thou couldest have no power at all against me, except it were given thee from above:"
