Windspeed and direction map

Wind is shown in two forms: 
1) as Wind arrows - the head of the arrow shows the direction in which the wind is blowing and the 'feathers' the strength; a short feather is 5 knots, a long feather is 10 knots and a triangle is 50 knots - add   the feathers to get the wind speed.
2) as warning regions where speeds above 22 knots are coloured; the colour bands correspond with Beaufort Force 6 and higher - Met Eireann.

 
Current Jet Stream Analysis - When the Jet stream is not over Ireland,  "seeing" is usually improved.
Bad "seeing" makes the stars twinkle more and reduces details visible on the planets through telescopes.
