If you managed to successfully disarm the ultrasonic sensors but the alarm still keeps going off you can rule out the sensors, and the high winds. Yes, the high winds/buffetting can cause false alarms by fooling the sensors.

It sounds like a dorr/boot/bonnet sensor is playing up.

As far as I know there is no way of adjusting the alarm settings yourself.

After the alarm has gone off, when you unlock the car you should hear a series of "quiet" beeps - the number of beeps should tell you what triggered the alarm.

I don't know what the sequence is, but if you count the beeps and then phone a Renault garage they should be able to tell you - al least you could then narrow it down to boo, bonnet, or doors - hopefully it will reveal a boot or bonnet problem, otherwise you would need to check all four doors!
