Where does Klystron 9 come from?

In 2009, Bay News 9 unveiled Klystron 9. Folks who were hoping it was the name of a laser-shooting mega-robot or home planet to advanced alien life forms were sorely disappointed. No, it was an updated version of their current Doppler radar, used by meteorologists to predict and analyze weather patterns, such as storms or temperature fronts.

At its debut, the network boasted the Klystron 9 as “the most advanced, most powerful, highest resolution broadcast weather radar in the world.”

The name Klystron 9 is derived from radar’s klystron tube, a special kind of electron vacuum tube that amplifies radio frequencies, and the 9 in Bay News 9.

Klystron 9 is well known in Florida, even in areas further removed from the Tampa Bay area where the radar is based. It is also notable for the jingle that plays to introduce images or information from Klystron 9.

Although there tends to be better coverage during the afternoon, keep a close eye on Klystron 9 if you have outdoor plans.

Storms are possible early in the Gulf and at the coast, with the onshore wind pattern. So, if your plans include a morning walk on the beach, keep a close eye on Klystron 9 early today.
