Look like a carrier modulated by a harmonically rich waveform, which
reduces in frequency...... 


then after a time the carrier is modulated by a harmonically rich
waveform that now increases in frequency......

Not too difficult to imagine?

What's the time scale on the spectrogram?

A motor that slows down, stops and then speeds up?
