Dust fall in some patchy light rain on the morning of 30th here in Penzance. There was also a brief light shower around 18:00 which appeared to drop more dust, though it may have just been re-arranging the earlier fall.

I've seen dust reports coming from Falmouth, Okehampton and Exeter too. On the basis of trajectory analysis, the source was certainly north Africa, western Libya and possibly Tunisia: not a particularly common source (most of the dust reaching the British Isles comes from the western Sahara).

There was also a minor dustfall here (Berkshire) today - a few spots of rain, probably late morning, contained dust sufficient to mark car windows and paintwork. Consistent with white 'dusty' skies and reduced surface visibilities too, and of course high temperatures in the south-easterly flow from north Africa.

Any additional dustfall reports welcome, on this forum or in your monthly COL notes - I'll prepare a short analysis of the event for April's COL bulletin.

Dust fall here too in north Lancashire. Seemed to build up during the day. A light coating was visible this morning,, but after a little (a trace) of rain more dust had been deposited. The deposits continued this evening too as there were further very light accumulations on my car after coming out of a meeting at 1900 BST.

As ab addendum to the dust of yesterday I noticed that the rainwater in my 5" manual gauge was a little cloudy when I took the reading this morning.

I too noticed a light coating of dust on my van this morning after a wet day yesterday. Have not noticed anything cloudy in the rain gauge though.

Fairly heavy deposits of red dust here at Arnold, Nottinghamshire on 2nd and 3rd April. Light rain turned the contents of the raingauge to reddish sludge. I washed my brand new car yesterday to get it looking nice to take my girl friend out for lunch today. By 08.00 this morning it was covered in red splodges again! Used the wipers so I could see through the windscreen and the screen wash produced a layer of sludge. Obviously, one of the most useful instruments for meteorological observers is a freshly washed, gleaming, new car.

Regards to all

Even a sightly worn car works well! I've attached 2 pics of my car covered in dust. The red car on 20th June 1998, the white on 19th April 2010.

On the same dusty topic I've added a photo of Mount's Bay taken on 8th April 2011. On this occasion the dust was reasonably high, and visibility at sea level was good, but despite there being no virtually no cloud it was incredibly dim, the sun just a faint glow. My solar panels which would normally produce around 1.5kw in the sun late morning in early April were producing barely half of that. I've never known daylight reduced anything like that in a largely cloud free sky.

Nothing like that today, absolutely glorious http://www.sennen-cove.com/4apr14.htm .
