cold. Low pressure indicates hot air. Rapidly dropping pressure indicates high winds and a possible storm front.

What causes barometric pressure?
Barometric pressure measures the weight of the air.
What is Air pressure on a station model?
the barometric pressure
Why is barometric trend important to know?
The Barometric Trend will tell you the air pressure. If the air pressure is high the weather will be clear and sunny, but if the air pressure is low the weather will be cloudy.
Why is the barometric trend important to know?
The Barometric Trend is important to know so as to be able to tell air pressure. If the air pressure is high, the weather will be sunny, but if the air pressure is low, the weather will be cloudy.
Is barometric pressure connected to the temperature?
Barometric pressure has everything to do with temperature. There is a simple way to understand the relationship... The higher the temperature is, the lower the pressure. The lower the temperature is, the higher the pressure. Reasoning: Barometric pressure is caused by expansion and contraction of gaseous molecules(the air we breathe). Heat causes the molecules to expand, and become less dense, causing the warm air to rise, and pressure to be dropped. Cold causes the molecules to contract, making the air become more dense, and fall closer to the ground. Heat is rapidly moving, generously spaced molecules. Cold is slower moving, closer spaced molecules.
What causes barometric pressure?
Barometric pressure measures the weight of the air.
What causes the winds to rush toward hurricane areas?
A hurricane is an area of low barometric pressure. This tends to pull air inward.
What is Air pressure on a station model?
the barometric pressure
Why is barometric trend important to know?
The Barometric Trend will tell you the air pressure. If the air pressure is high the weather will be clear and sunny, but if the air pressure is low the weather will be cloudy.
Why does wind occur when air tends to move from regions of higher to lower?
Pressure
How does barometric pressure influence weather?
High pressure situations are generally associated with fair, sunny weather. As high pressure is an area of sinking air, and air tends to dry out as it sinks, leaving sunny skies.
Why is the barometric trend important to know?
The Barometric Trend is important to know so as to be able to tell air pressure. If the air pressure is high, the weather will be sunny, but if the air pressure is low, the weather will be cloudy.
What air pressure do anticyclones have?
Anticyclones produce high barometric pressure.
When air expands and pushes it is called?
barometric pressure

What is atmospherical pressure at higher and lower altitude?
In general, barometric pressure, or atmospheric pressure, drops as you go up in elevation. For example, at 18,000 ft. above sea level, the average barometric pressure is about half the average pressure at sea level (see the related links for charts) However, barometric pressure also varies widely with the weather (weather charts almost always show the movement of low pressure and high pressure zones), so true barometric pressure cannot simply be calculated, but must be measured. In the United States, the National Oceanic and Atmospheric Administration provides hourly barometric readings for many locations across the country (see related National Weather Service measurement link)
What are the use of barometer?
A barometer is a instrument used to measure air pressure
