Do we get warmer & colder air from "elsewhere", or does our "local" air temperature simply rise & fall?

Question

Logic would have it that air travels all over, right along with the clouds & the rain: but what about smog, etc.? And why would one place be reputed to have "fresh air" over another place?

Answer 1

Actually, both of what you said is right. When warm air forms over another region, it usually is traveled by the winds and whatever direction the winds are bloing from will decide what type of air mass your region will receive. For example, if you lived in San Antonio and the Wind direction was from the NW, then your temps will be cooler because of what's left of the artic air leaving it's final marks (which isn't much at all) on san Antonio. However, if it was blowing from the SW, then expect Hot, Dry conditions courtesy of the wwind blowing the hot desert air over the area. Of course, the sun also decides the temps in given locations too. If one area is overcast but another is Sunny, although there receiving the same general air mass, courtesy of the Sun, the Sunny region would be warmer because they're receving a better source of heat energy besides the traveling of air masses.

Answer 2

Some weather comes from upper air currents and these always come from elsewhere. We also have local effects such as inversion layers which trap air pollutants in a given region, thus creating smog. Smog clears when upper air currents are strong enough to clear the local effects.

Answer 3

Both are possible.If you assume that there is no wind at all on a particular day over a particular place, then local air temperature only rises and falls.On the other hand if there is a strong wind thorought the day, warmer or colder air comes from elsewhere.

Answer 4

Air masses from different areas determine whether we have cool (or cold) dry air as opposed to more mild or warm humid air. For instance, in Ohio, we often get cold dry Canadian air masses that will give us below normal temperatures. We also get warm humid air masses from the Gulf region that give us above normal temperatures. The jet stream position determines what kind of air mass we will be in too. Less polluted areas will have more fresh air than others.

Answer 5

Actually, both can apply. In the Eastern US, weather systems move warm and cold air in and out of areas. However, the warm and cold air can be moderated over distances as they move, and there is a basic daytime heating and cooling impressed on them. In the summer, high pressure systems often slow down and pollutants build up as the air circulates around over the same area again and again.

Answer 6

it's necessary to realise that everything is connected with one another on this earth. It has to have an influence, there is no other possibility. The fresh air people talk about is that there are little pollutants in the air like dioxins, fine dust or other toxins. this in relation with the build and structure of this earth and is therefore subjected to all physical laws.

Answer 7

warm air would not upward thrust because of the fact it is warm, nor does chilly air sink because of the fact it is chilly. Denser air sinks, much less dense air rises. in case you bypass up interior the troposphere you will see that less warm air is overlying warmer air with the warmest air on the floor and the coldest on the tropopause. If the upward thrust and fall of air became via temperature, you will not discover that undertaking. even in spite of the undeniable fact that the air larger interior the troposphere is less warm than the air under it, it is way less dense because of the fact it has fewer molecules consistent with unit quantity. The densest air is on the floor. in case you heat the air on the brink of the floor so as that that is going to become much less dense than the air above it, that is going to upward thrust in spite of if it does so because of the fact of density no longer temperature.

Answer 8

constant motor velching in urban areas cloud the city with smog all day, as opposed to "fresher air" in the rurals or provinces.

Answer 9

smog can move too.
