Here's why:
* Barometers are ground-based instruments: They measure the weight of the air column above them, reflecting the pressure at that specific point.
* Storms are complex, multi-layered systems: They have varying pressure gradients and wind patterns at different altitudes.
* Pressure variations within a storm: The pressure within a storm changes dramatically from the surface to the upper levels. A single barometer reading cannot capture this variation.
To track storms at different altitudes, we need specialized instruments like:
* Weather balloons: These release sensors that measure pressure, temperature, humidity, and wind speed as they ascend through the atmosphere.
* Radar systems: These use radio waves to detect precipitation and wind patterns, providing information about storms at various altitudes.
* Satellites: These provide wide-area coverage, capturing images and data from different altitudes and measuring atmospheric pressure.
So, while a barometer is useful for observing local pressure changes, it cannot provide information about the internal workings of storms at different altitudes.
