How to Predict the Weather Using a Barometer?

1 Answer

Answer :

Of all weather instruments essential to forecasting, thebarometer tops the list. Why? Because every weather change ispreceded by a rise or fall in air pressure, and air pressure isjust what the barometer measures.If you compare two barometer readings taken an hour or twoapart, you will know immediately if the air pressure is rising,falling, or staying the same. And as a result you will be able,with a fair amount of accuracy, to predict tomorrow’s weather.RISING BAROMETER: When the air pressure measures higher than itdid in your previous reading, the air is becoming denser, and thebarometer is said to be rising. This tells you that clearer, drier,cooler weather is on the way.If the barometer is rising very rapidly from a low position, theweather will clear up very soon, and it will probably
