Arkan,
Welcome to ST. I am not a chase team member and cannot hook you up with one, but can you be more specific in your question? Are you seeking to travel with and film/photograph a chase expedition? Or are you wanting to examine data and collected imagery without being present on the chase itself?
If you are experiencing ST for the first time now, while convective activity is at a low point, you can look forward to checking out the Target Area section, within which March-into-July Forecasts & Nowcasts will buzz with a marvelous scale of items -- from suppositions to detailed pinpoint forecasts and real-time observations from lab and field -- all composed by a variety of weather observers who range from the purely intuitive to the highly educated. Mobile internet connectivity allows chasers to post photo and video captures while in pursuit, and later wrap up the experience in detailed report in the Post-Storm Discussion list.
Some of the best photographers and videographers anywhere are regular contributors here. We may argue amongst ourselves, especially in the offseason, but we are incredibly blessed with talent that knows what to do and when to do it. If you make ST part of your daily ritual for one year, you will have 'documented' a batch of experiences that will help prepare you for your own chases. We seem to be enjoying more significant reports and images from Canada in the last few years, so you will be reading and hopefully interacting with chasers familiar with areas close to you.
Of course, nothing compares to going out after a storm, but you can train your brain here to help prepare yourself for the mistakes everyone makes while starting out. I've been starting out for about thirty years...
I'm sure others will respond here -- good luck and enjoy.
