High pressure: The isobars will be far apart. Low pressure: The isobars will be very close together.

How do you know if the air pressure is the same or different in different places?
Atmospheric pressure is measured by weather stations in many areas, using devices called barometers to monitor the changing pressure. Air pressure varies within weather systems and by altitude (elevation).
How do you determine the atmospheric pressure using Boyle's law?
Actually , the atmospheric pressure is constant i.e 1 atmosphere. So, it's already determined....
What is the barometer used for and how does it work?
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries.
What is the difference between a high pressure geyser and a low pressure geyser?
A low pressure system is a weather system surrounding an area of low pressure (low mass of air above) that is surrounded by air moving inwards and counter-clockwise. Low pressure systems are usually characterized by clouds and precipitation. High pressure systems are the opposite. Air flow is outwards and clockwise and usually clear weather.
How global weather is monitored?
By using a thermometer and the barometer.=)
How do you use a geostrophic-wind scale?
A geostrophic wind scale is a graphical device printed in synoptic weather charts available on weather fax or on the internet, like the ones compiled by Bracknell and other weather services. It enables estimation of the geostrophic wind velocity by measuring the distance between the isobars (lines of constant pressure) in the weather chart and plotting this against the geographic latitude in the wind scale. step 1: determine the geographic latitude of the position you want to estimate the geostrophic wind speed for. step 2: measure the distance between the pressure lines (isobars) shown on either side of that position. step 3: choose the correct latitude line in the geostrophic wind scale or interpolate in the scale, using the result of step 1. step 4: plot the distance measured in step 2 on that line. step 5: read the estimated wind speed from the scale, using the curved lines. NOTE that the geostrophic wind is only a theoretical wind flowing parallel to the isobars in the chart. The true wind always is reduced by friction against the earth or sea surface and will be deflected towards the centre of the low pressure system which is circled by the isobars you used.
What is a sentence using air pressure weather and wind?
As the air pressure dropped, the winds picked up and the weather turned foul.
Why are streamlines rather than isobars used on surface weather maps in the tropics?
Streamlines are used on surface weather maps in the tropics because they better represent the flow of winds and illustrate the dynamic patterns in the region. Isobars, which connect points of equal pressure, may not accurately capture the complex wind patterns that are prevalent in the tropics due to various factors such as local terrain, convection, and tropical cyclones. Streamlines provide a more detailed and accurate representation of wind direction and flow in these areas.
How would you determine the maximum inflation point when taking blood pressure?
you can determine the maximum inflation point when taking blood pressure by using palpation.
What are the lines on a map that connect points of equal pressure called?
The isolines that connect the points of equal atmospheric pressure are called iseidomal. These terms are common when using the barometer.
How do you know if the air pressure is the same or different in different places?
Atmospheric pressure is measured by weather stations in many areas, using devices called barometers to monitor the changing pressure. Air pressure varies within weather systems and by altitude (elevation).
Can you make a meaningful sentence using the word air pressure?
Different levels of atmospheric air pressure affect our weather every day.
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.

Why is using a weather map important?
weather map is so important for us.with the help of weather map we can determine the average temperature and mean rainfall,climatic condition,movement of wind and the vegetation of a particular region
What are some things that can be measured using an automated weather station?
temperature, pressure, humidity, cloud ceiling, rainfall...
Where did we get the pictures of weather systems we see on television weather reports?
They are created by weather forecasters using a lot of data sources. There are weather stations that collect data and satellites that do so too. All of this data is put together and then they can work out where the weather systems are and the areas of pressure, what level the pressure is and so on. When they have this data they can create the maps and pictures by hand or computer.
