Why does a change in air pressure tell you about the weather?
because the hot air push up and the cold air go in that area
What does a change in air pressure tell you about the weather?
Rising air pressure would tell us that the air is being compressed downwards and is being warmed therefore causing clouds to disapear and more sun to prevail. Hope this helps! :)
What do close isobar lines represent?
Weather Maps: An isobar that is a closed circle indicates an area of high ("H") or low ("L") pressure center. Geographic Maps: An elevation on the map you are looking at. Sometimes numbers accompany the ring, to tell the elevation. Some times there are no numbers.
Why is a Baromerter used?
it is used to measure the air pressure which is useful for the meteorologists to tell the weather, the air pressure is measured in millibars!
What the basic instrument for measuring atmospheric pressure?
This would be a barometer. When the air pressure drops, you can expect rain or other bad weather like thunderstorms. On the other hand, when the air pressure rise, you can expect better weather. You can tell by using a barometer.
How can you tell that the weather will be fine?
high pressure usually means good weather
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.
If the weather forecaster tells you that the pressure is falling what is the air density doing?
They tell you exactly the pressure is falling when the density of the air around us gets less, this means that air from other area's will be moving toward us to fill the air pressure up, air always moves from a high pressure area to a lower pressure area
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.
Why is the weather difficult to predict with 100 percent accuracy?
Weather is an extremely unpredictable system. One moment meteorologists may be able to tell a low pressure is in the area when a quick change in temperature changes that low pressure to a high pressure. Meteorology, like many other sciences, are not always straight forward and accurate.
Why does a change in air pressure tell you about the weather?
because the hot air push up and the cold air go in that area
What does a rising barometer tell you?
Mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir. High atmospheric pressure places more force on the reservoir, forcing mercury higher in the column.
What does a change in air pressure tell you about the weather?
Rising air pressure would tell us that the air is being compressed downwards and is being warmed therefore causing clouds to disapear and more sun to prevail. Hope this helps! :)
How can you tell when bad weather is coming?
Your can tell by looking outside when determine if its low pressure or high pressure.If you have low pressure then its ever going to have precipitation or bad weather.High pressure means sunny and humid outside.You can also look at the cloud,if its stratus then it means bad weather.There are differenet type of cloud.Good luck!

How can you tell you have preclamsia?
If you have this disorder you will have high blood pressure. If you are pregnant with high blood pressure this can be dangerous. Your doctor will help you lower your blood pressure.
