Explain why barometric pressure usually falls with the approach of a cold front or occluded front?
falling down
What happens to a barometer when a cold front comes in?
decreasing
How are the spacing of isobars and wind speed related?
Distribution of isobars on a map is connected with the direction and speed of the wind. As the isobars grow closer together it shows a rapid change in barometric pressure, which can indicate a storm front approaching - and that usually means increased winds.
What will be the millibars and barometric pressure formed by the combination of the Canadian cold front meeting Hurricane Sandy in western Pennsylvania and Ohio?
A barometer reading of 30.71 (1040 millibars) is a typical winter reading for a high-pressure, cold-air cell moving out of northern Canada. Generally, in Ohio, a cold front doesn't force the barometer below about 29.8. Sandy is predicted to create a very low millibars (barometric) reading, lower than 960 millibars. Currently approximately 300 miles offshore at 8am Monday Oct 29th 2012, Hurricane Sandy is at 946 millibars. The two massive storms will likely drop the barometric pressure into the 29-plus range, but how far it will drop is not yet known. However, a 29-plus barometer reading along with the cold, wet weather is certainly apt to increase the pain of chronic pain sufferers, along with devastating damage for people along the coast with power outages, trees toppled, etc.
What is the zone where high pressure areas and low pressure areas meet?
The zone is called a front. There are a few types of fronts. They are: cold front, warm front, occluded front & stationary front.
Explain why barometric pressure usually falls with the approach of a cold front or occluded front?
falling down
As a cold front passes barometric pressure should?
It will rise after the front passes.
If the temperature increases and the barometric pressure falls then what is likely occurring?
Warm, moist air mass is approaching as a warm front
Barometric pressure tends to be higher when air is what?
cold. Low pressure indicates hot air. Rapidly dropping pressure indicates high winds and a possible storm front.
How does barometric pressure affect gauge pressure?
Assuming we are using a pressure transducer to measure barometric pressure, I understand that a gauge type transducer would be used. The internal diaphragm would have a fixed pressure behind it (at a guess would be at standard temp/pressure, STP, ie 20 deg C @ 1013mb), so the transducer has a reference to work against. The front of the diaphragm would be exposed to atmosphere. I would assume the reference (gauge) pressure would vary as the barometric pressure varies, as the diaphragm would move towards the side with least pressure, or at 1013mb the diapragm would be in the centre (which could be used as the null output voltage), higher than 1013mb could produce a positive voltage swing, less than 1013mb could go negative. This is all I can think of, please let me know if on the right track.

Do you measure from the front of the board or the back of the board for your approach for the long jump?
back of the board for your approach and front for the jump
What does the scientific saying When grandmas bones and bunions ache expect the clouds to fill the lake mean?
It means that there is a storm coming. When a cold front comes in and you have arthritis, your bones will ache. As people age, their joints get looser and these pockets of less tight tissue can detect changes in barometric pressure and let people know of approaching rain. People who have had joint surgury know the experience as well. When a storm approaches, the barometric pressure changes as the storm front either moves a cold or warm front out of the way. This change can be felt hours or even days ahead of an approaching storm system.

Is high pressure warm front or cold front?
warm front is low pressure , cold front high pressure . because it pushes down on the surface (because cold air sinks) it makes high pressure .
Why does Aneroid barometer 2 pointers?
The pointer that does not move except by a knob, usually on the front, is just for comparing the movement of the pointer which reads barometric pressure. By lining them up, you are able to detect slight movements easier. I think that's the only reason for that other pointer. Hope this helps.
What is frontal pressure?
It is a pressure which comes from the front
