A Windy Day

Many thanks to Kilchoan Early Bird for these pictures from the windswept bay to the northeast of Ardnamurchan Point lighthouse.  As promised, the winds were strong during the night and through the day.  A bit of blustery weather makes a nice change from the dead grey days we've had recently.

Kilchoan Early Bird found this washed up on the beach.  From the size of the barnacles that have grown on it, the device has been in the sea for some time.

This is a close-up of the top of the box.  To the left is the word 'Radiosonde' and to the right 'VAISALA' and the address www.vaisala.com

The Diary has been on the Vaisala website, here, and can't find a maritime product that looks like this, so has now written to Vaisala.  Does anyone know what it is?

Many thanks to Kilchoan Early Bird for all the pictures

    Is it the bit that hangs under a weather balloon?

    The radiosonde is the part of a weather balloon that takes measurements. You can report finding it here:

    On their web site are some weather monitoring devices that look a good match, so Dufffish maybe correct.

    If you look on their website under meteorology it's listed under upper atmosphere instruments, so probably part of a weather balloon.

    Yes definitely a probe from a weather balloon. See another one here: http://en.wikipedia.org/wiki/File:GPS_sonde_ready.jpg

    There is a Wkipedia article here too: http://en.wikipedia.org/wiki/Radiosonde
