Blue Sky,
Judging from your pictures I would speculate that you have pictures of trailing edge vortices. However, if it would be useful to you I will endeavor to review the records I have access to for region 9, Monterey Bay.

For your pictures it would be quite useful if you recorded the exact time the picture was taken; the orientation of the camera [both in a north / south fashion and angle of elevation with 90 being straight up and 0 being horizontal]; and the approximate altitude of the artifact [in meters].

Please reply if you would like me to look into this for you.
