What Barometers Measure
Comparing Barometer Changes
Once you know what the average atmospheric pressure should be, following weather is one step closer. Barometers measure pressure in several units, usually inches or millibars. For the sake of efficient demonstration, let's assume the average pressure of a given area is 29 inches. Here's what can happen to that barometer reading:
Some barometers have weather indications inscribed on the meter face. This excellent tool for explaining readings make barometers more accessible to the general public.
Keep in mind that there are exceptions to reading barometers. Develop skills through daily comparisons of barometer readings and observed weather. Keep a log of barometer readings and refer to it frequently. Over time, experience in forecasting weather can make anyone a decent amateur (perhaps professional) meteorologist.
