Artists may carry sketch pads or painting equipment to the field to record weather events. Others jot down poems or impressions of a scene. I like a camera around for capturing that special sunset or magnificent cloud formation. Some folks, mostly storm chasers, prefer to carry a video camera to capture the event. Some weather watchers, such as storm chasers, want to have some idea of what type of weather is pending and where it may occur so they can plan their weather watching activity.
Weather radio can be a help as well.
In fact, a simple portable AM radio makes a good thunderstorm indicator. Tune it to a frequency away from local stations and listen for the static. Lightning, miles away from view, will reveal itself as static bursts. Wind Chimes can aid weatherwatching and add the enjoyment of hearing the wind.
