A barometer is a scientific instrument that is used to measure air pressure. Pressure tendency, which is derived from barometric readings, can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.
The analysis highlights History, Applications, Measurement and Science as prominent areas in the source structure around Barometer.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
