    Hi guys

    what i am looking for is "wikipedia or anything else" type of site that gives a description of all the little signs that appear on a weather chart in a "universal standard"

    I dont quite know what to call the little inverted "f" with three legs that shows wind direction and speed AND why are they in different colours on

    http://grib.us/

    i cant find descriptions on Grib either - their help menu is poor and nothing on the site. The download works pretty OK

    i would like to have a printout on my boat of all the meanings of all little "signs" etc.

    the best i found was on the map included but it is not quite the same - it is 3 MB chart but rather nice to have in your collection of weather data

    so what are the standard weather chart signs to be used?

    the little lines indicating wind direction (no head to the arrow) but the "tailfeathers" mark wind-speed in knots 5 knots = half length and 10 knots = "full size" and 25knots = 2 full size and 1 of half size and so on... can't recall seeing more than 45knots (full gale?) as expectation of gusts at +40% I think...

    The met office still uses the little circle for wind speed and not the "tailfeathers"

    please see if you guys come across a tailfeathers page:idea:

    anyway thanks for the input so far:D

    Eh Manie,

    Want to know things about the weather ? Here's a neat guideline for you.

    Easy to impliment on any boat.

    Manie, a KISS way to remember which is left and which is on the right, all the words in pairs and the ones with less letters go together "left", "red" & "port" and then the others must be on the other side "right", starboard" & "green" - so how do you determine which is "left"? well - guess, then on probabilities you will be correct, or, (right?) 100% of the time?:D:D:D:D

    I like determining the weather by the testicles method - humidity can also be evaluated, amongst other things (if there is a bucksom naked lady nearby?) - like blood pressure and testosterone levels... and if you are alive?......
