The BBC regional forecast often discribes the sea state as wavelets, I have never heard this discription before so does anybody know what wavelets mean?
Thanks Mike

Little waves. There's probably a definition of them being <0.5 metres, or something.

A wave from the wrist, not moving the forearm. Like the queen does.

BBC couldn't give a proper weather forcast if it was spelt out to them.

The BBC don't give weather forecasts. All their Broadcast Meteorologists are employed by the Met Office.

Ooooohh, where's my handbag, ahh, here it is. By "Give" I suspect he meant "Present". But now I'm a little pedant too, Doh!! /forums/images/graemlins/confused.gif

Can you be a little pregnant? Swiss viewers have complained about pregnant weather girls have the wavelets arrived since ours became pregnant?
Its become a worldwide phenomenon

I think you will find I have posted this pic in the past.
Ha!
I don't know where the 'l' comes from . Small maps are mapettes so it should be wavettes.
We get a specific forecast for the Lake District which is extremely accurate Weatherline

Despite the scoffing above, "wavelets" is a genuine meteorological term going back at least to the 1930s.
A liitle bit of history:
The Beaufort Scale originally defined the wind force in terms of the canvas that a full-rigged sailing frigate would carry. In 1939, the International Meteorological Organisation finally put their heads above the parapet and decided this was out of date, and decided that (bearing in mind most vessels did not have anemometers) it would be better judge wind force from the appearance of the sea surface. The specification which they came up with:
Force 0: Sea like a mirror
Force 1: Ripples (height <0.1m), with the appearance of scales.
Force 2: Small WAVELETS (ht 0.2m), short but pronounced, crests have glassy appearance.
Force 3: Large WAVELETS (ht 0.6m), crests begin to break, perhaps scattered white horses.
Force 4: Small waves (ht 1.0m), becoming longer,; fairly frequent light horses.
....and so on. So, when they say "wavelets", it should coincide with forecast winds of about 4-10kts.
However, having trained as a meteorolgist, and therefore expert in the use of seaweed, chicken bones and fiction-writing, I could be just making this all up.....
