The sunroof is manufactured exactly the same way as a caravan window which is an inner and outer layer. The bonding that permanently secures the two halves has delaminated which the high winds are forcing rain water through the offending area. The repair would be identical to that of window delamination but you may have to remove the sunroof to undertake the repair.

You can do it yourself but you would have to remove the two support struts inside the caravan first then get on the roof and remove the complete sunroof via the three hinges and under take the repair the same as treating for a delaminated window. However, the nature of the task would be best done under cover either in a workshop or similar or on a dry day (no rain).
The basic tools required are a type of glue specially for bonding acrylic plastics, G clamps and white spirit. You will have to find where the delamination has occured, clean the surrounding area with white spirit, apply the adhesive at the required area and then clamp the two halves of the window together with the G clamps and leave over night for the adshesive to cure. However, with the shape of the window perimeter contour won't be flat so you may need to make some corresponding fixtures out of small pieces of wood which is easy to do if you have knowledge and experience with DIY tasks. If the hinges are removed from the roof then they will need to be re-sealed as well with the appropriate waterproof sealing agent.
If the task is deemed to be too difficult then it may need wise to have it done professionally but they may well say that it requires a new sunroof as many companies are reluctant to repair components due to the labour costs involved so it works out cheaper to remove and replace.

Also have a look if there are any screw/fitting seals that attach the roof to the opening/support mechanism, they may have perished allowing water ingress.
