A shower is named after the constellation from which the meteors appears to originate. New showers will be established as future cometary debris crosses Earth's orbit. Existing showers will eventually fade away as debris dissipates. The Perseids have been around for a thousand years, while there is no indication of the Quadrantids further back than 200 years. Shower intensity varies and cannot be predicted accurately from year to year.
Some forecasts are available in the popular monthly astronomy magazines.
I have never experienced a meteor storm. The last reported storm was associated with the Leonids in 1966. For a period of about an hour, more than a hundred thousand meteors pierced the sky. Storms result when the Earth hits pockets of concentrated silicate particles. The debris from future comets may also produce such displays.
