TEACHING MOMENT: Detecting Weather Patterns

We have recently observed the movement, intensity and paths of a few 2018 hurricanes.  Ground motion, which is measured by a seismograph, can be detected as a storm approaches land fall and then moves across the States.  (See TXESP’s example from 2017 Hurricane’s Season —>>click HERE).

When the air pressure, wind speed and temperatures changes, we can observe the combined affect on the ground measurements in a seismogram.  Look at this snapshot from Station E1TX, recorded on an EQ1 educational seismograph, can you estimate what time the cold front blew into Houston??
