How would you expect the reading on a barometer to change as a storm moves into your area?

Yes. You would expect the pressure to drop. A low pressure system consists of rising warm air that swirl around a center. Because the air is rising, it lowers the air pressure pressed on the ground. Because of this the pressure-sensing barometer will read that the air pressure is lower.
Lower pressure means rain because the warm rising air makes clouds. Expect the pressure to drop as a storm is a low pressure system. Note that cyclones/hurricanes have even lower pressure.

An instrument used to measure Stormy Rain Change Fair and Very Dry. Made in Western Germany. May have been used for boaters.?
Disregard the words Stormy, Rain, Change, Fair and Dry as these are onlytraditional zones on a barometer dial. Your barometer indicating hand willnever move all the way to Rain to predict rain or to Stormy to predictinclement weather. The normal operating range of movement for your barometerindicating hand is from 1000 to 1030 hPa. Your most extreme readings wouldoccur before a hurricane or tornado when barometers have dropped as low as970 hPa (28,5 inches of mercury); or, at the other extreme if very fair, dryweather is to come, your barometer may rise to 1050 hPa (30,9 inches ofmercury). The following procedure, if done every 12 hours, or morning andevening, should give you the best results.1. Tap the instrument lightly to release any latent action.2. Adjust set hand directly over the indicating hand. This is your momentaryreading. At a later period you will be able to notice in what direction theindicating hand has moved since the last setting.If it moves to the right you have a rising barometer which usually means achange for the better or continued good weather. If the reading is to theleft you have a falling barometer, which usually means a change for the worse.A steady barometer means no change. For accurate weather predictions, it ishighly important that your barometer be adjusted to sea level. The correctsea level reading can be obtained from your Weather Bureau or televisionweather forecasts. Readings obtained from your barometer indicate weatherconditions that may prevail within the next 24 to 48 hours, providing winddirection and velocity remain the same as when readings were obtained.
What are the uses of anaroid barometer?
A barometer is used to measure barometric pressure. An aneroid barometer has a sealed chamber with some air removed, creating a vacuum. A chain, lever, or spring connects a needle to a plastic disc covering the container. The pointer moves left to right as the air pressure increases or decreases.
When a substance moves from one state to another what kind of change occurs?
a phase change
How does a barometer work?
There are a couple of types. By far the most common is the aneroid barometer. The heart of an aneroid barometer is a sealed can. As the surrounding pressure rises and falls, the can shrinks and expands. A mechanical linkage translates the deflection into the movement of a dial. It could also be measured with a strain gauge, with the resistance translated into pressure.The Mercury barometer has a tube sealed at the top, full of mercury sitting in a cup full of mercury. A vacuum forms at the top because the exterior pressure can only support a column equal to the height times the density of mercury.Air pressure pushes on the mercury inside of the container, the mercury moves up the glass tube. The greater the air pressure the higher the mercury will rise.
What kinds of changes occur as an air mass moves over an area?
there could be a temperature change, or a physical change.
What is the change in temperature when the thermometer reading moves from -10 to 15?
It is a change of 25 units.
As warm dry air moves into an area the barometer will be?
increasing
When the moist humid air moves into an area the barometer will be?
decreasedecreasing
What does it mean when the straw moves up barometer air pressure?
If you have taped a straw to a balloon stretched over a jar top as a simple barometer, when the straw moves up, this is a sign of high pressure (atmosphere pressing down on the balloon). High pressure usually means fine weather.
How does the sensex moves up and down?
it is the barometer of the largest 30 companies, so the performance of these companies is depicted by the points.
