what is the barometer (if that is spelled right) or pressure that I see in weather stuff?

A barometer measures current atmospheric air pressure. It literally measures the weight of the atmosphere where you're located. Generally, the higher the barometric pressure the better your weather will be.

Manometers are used to measure pressure. It's basically a u-shaped tube with a liquid in the bottom (usually water or mercury) and it is sealed on one end. As the pressure increases, the liquid is pushed up into the sealed end. By graduating the tube, you can use it to measure presure.

"compare"\n\nDewpoint and barometric pressure have no direct relationship.

Lower pressure is indicative of rain and higher indicative of fair weather.  Think about how low the pressure is in a tornado or hurricane, like they're sucking, which they are (like a vaccuum).  29.93 is likely fair weather unless the barometric pressure is falling.  You should have a needle you can adjust.  Put it on the current reading and check it again in a couple hours.  If it's falling then rain is likely coming.  If it rises, then clear.

Anywhere there is a difference in pressure. Examples:\nLow pressure in a vaccum cleaner, higher pressure outside pushes the air into the cleaner. Different pressure in a house compared to outside, when you open a window the higher pressure flows to the lower pressure. Remember that it is always a push and never a suck. Science never sucks!

doppler radar.  or just your ave thermometer.  elements? like rain thunder?  i would pick sun.  i like the sun baby.

An isobar shows regions of similar air pressure.\n\nAn isotherm shows regions of similar temperature.

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

Are you sure there is a relationship between these variables?  \n\nCan you define pressure tendency? Do they make a pressure tendency gauge?

There are several way in which a barometer work.  The most common is a needle attached to a spring and a tensioning device which expands and contracts based upon the amount of atmospheric pressure it is exposed to.  \nThe second type is what is called Galileo's barometer.  Globes are filled with a number of\nliquids of different specific gravities (this is the density of the liquid with respect to the density of water).  As the air pressure changes, these different globes will either float or sink based upon the changes in air pressure.   The third type is the electronic barometer.  It uses a pressure transducer, which causes changes in electric current bases upon changes in air pressure.  These changes are converted into either an analog (needle meter) or digital display of the value of the air pressure.

No, it means that you should take your umbrella with you, because the humidity in the air, and the pressure system suggest it could rain.  Weather prediction isn't exact science, so basically... they never KNOW for a fact if it is raining or not... no matter what percent they give.

this is a weather term - it means an area of high pressure, leading to little or no clouds in the sky (i.e. hot weather in the summer, or cold nights in the winter).

it is when 2 pressure systems meet, I think they just follow barometric pressures and estimate where they will meet

It has to do with high and low pressure systems. Wind moves from high-pressure areas to low-pressure areas.

A pressure system is a region of the Earth's atmosphere where air pressure is unusually high or low. High and low pressures form (and die) constantly due to thermodynamic interactions of the atmosphere and water in oceans, lakes, and other bodies of water.\n\nLow pressure systems are normally associated with storms unless they are tropical storms or cyclones in which case those symbols are used. High pressure symbols are often associated with fine weather although if the highs are from the arctic it can also be associated with cool weather. Low pressure systems are normally symbolised by L while high pressure systems are indicated by a H.
