What else can I help you with?
How would a barometer reading change with a cold front?
A barometer reading would change with a cold front because the density of mercury will change with temperature, so a reading must be adjusted for the temperature of the instrument. For this purpose a mercury thermometer is usually mounted on the instrument. Temperature compensation of an aneroid barometer is accomplished by including a bi-metal element in the mechanical linkages. Aneroid barometers sold for domestic use typically have no compensation.
Does precipitation come before or after a warm front?
Not normally before a warm front, precipitation comes before and after a cold front. When you have warm air and a cold front comes through, you mix warm with cold and that brings precipitation.
What happens to the temperature and humidity in a cold front?
Temperature is lowered. Humidity is increased in a cold front.
What kind of front occurs when a cold front moves over a warm front?
When a cold front overtakes a warm front, it forms an occluded front. This happens when the cold air mass catches up and lifts the warm air mass off the ground. An occluded front typically brings a mix of weather conditions, such as precipitation and strong winds.
What happens when Warm air mass and cold air mass meeting and no movement occurs?
Hiwhat happens when exposed air meets foodThank you.
When a cold front comes through what happens to the warm air?
When a cold front hits, usually the warm air rises.

What happens when a cold front comes in to a warm front?
It pretty much sits still as the Warm Front passes 'overhead'. It will get pushed back/up a bit.

Would it be hot or cold if a barometer was dropping?
A barometer does not measure temperature it measures pressure.
How does air mass effect cold front?
When the cold front comes, the air mass gets lighter and thinner.
What happened to a barometer levels when there you cold weather?
during cold weather like rain storms or snow storms the barometer goes down. During warm weather the barometer goes up.
What happens when a cold front bumps into a warm front that is not moving?
it gets destroyed
When a cold front runs into a warm front what happens?
it starts to get coldthunder and lightning
What happen in a cold front?
A cold air mass comes in under a warm air mass.
