No. While you could make some vague predictions, you need a full set of temperature, pressure, humidity and wind speed and direction to make forecasts with any real degree of certainty.

Could a mercury barometer be used to measure the barometric pressure of the atmosphere on mars?
no it could not as the tempratues are very different
What tools do you use to to predict future climate changes?
You could use a sling psychrometer to get the relative humidity and predict tomarrows weather. You could use satilites to see what to atmosphere looks like and predict tomarrows weather.
How do weather tools help predict weather?
weather instruments are used to research the weather conditions. by looking at weather instruments, u can determine what the weather could be like. for ex., when the barometric pressure is dropping, it wil storm or rain. these tools are made to predict weather conditions
What day will it snow in springfield va?
The weather is hard to predict, check your local weather forecast. That is your best option, though they could be wrong.
What will the weather be when theres a low pressure trough?
Well it could be possible in fact the answer to the question is it is usually wet weather because the low pressure pulls high pressure towards the low pressure center where they make and create weather events.

What you conclude about the weather if the barometric pressure was dropping and you could see cumulonimbus clouds in the sky?
isss goneeee RAIN

How can a twelve year old predict weather?
A twelve year old might be able to predict weather by watching the news and weather stations on television. He or she could also use a small weather station that includes weather maps, precipitation monitors, wind monitors, and temperature monitors to predict weather.
Why can't my dog predict the weather?
This is probably because no dog can accurately predict the weather. Actually humans are only partially successful...Anyway, what do you mean? How could you tell if he were predicting the weather?

Does change in air pressure affect eyesight?
I've often noticed that my distance vision is slightly blurred only during stormy weather. Could this be caused by low air pressure (it seems like pressure would be equalized within and -out the eyeball faster than the barometric pressure outside changes !?) or refractive index of the air?

How do you use the Mitsubishi Pajero altimeter gauge?
An altimeter does not actually measure altitude directly, but rather just atmospheric pressure. So an altimeter is actually a barometer created for a specific purpose. The altimeter uses the changes in atmospheric pressure to determine the changes in altitude. Why does pressure change with altitude? Simply put, the pressure at any given point in the atmosphere around the earth is a result of the weight of the atmosphere above it (pulled down by gravity). For this reason, the higher in the atmosphere you are, the less atmosphere you have above, and the less pressure exerted on you. Measuring altitude with barometric pressure is not free from difficulties, however. Atmospheric pressure can also change with changes in weather patterns. On an uneventful weather day it is not too unusual for an air pressure change of 1 mbar, caused by temperature changes alone. This 1 mbar change in pressure could result in a skewed altitude reading of up to 26 feet (8 meters). But on an afternoon full of weather changes, like an approaching cold front, air pressure could change by as much as 5 mbar, or more. This could result in a skewed altitude reading of up to 130 feet (40 meters), or more. Typically, when bad weather is approaching, the pressure will be falling. And the altimeter thinks this decrease in pressure is due to an increase in altitude, so it will read higher than you really are. And the opposite is the case when the weather conditions are improving - the altimeter will read lower than you really are. In order to compensate for weather changes, an altimeter must be calibrated using a known altitude or a known pressure value. A known altitude can typically be taken from a specific landmark on a topographic map. But if you do not have a known altitude to use, you will need to use a known pressure value. This is typically done with a barometric pressure value. "Barometric Pressure" is the current air pressure at sea level, for a specific location. Barometric pressure is measured several times per day, and can usually be obtained from flight service stations or aviation weather reports. With all of the changes that affect an altimeter, your elevation can easily be skewed by a few hundred feet in as little as one day's time. You will want to calibrate your unit at least once per day, but for improved accuracy (especially in changing weather conditions), you may want to calibrate it every couple of hours at a known elevation.
Why does the weather cause a migraine?
A sudden rise and/or drop in barometric pressure could cause a migraine because or the fact that your body needs to adjust to the change and the faster the change - the faster your body needs to react. It is critical for people with migraine headaches to maintain a balance, and sometimes their bodies have a hard time adjusting to changes around them. It is also because a change in weather can cause allergies to flare up and trigger a migraine.
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.
