HOW TO READ A WIND BARB		ABOUT WEATHERZONE STORMTRACKER

	A wind barb is a compact means of representing both wind speed and direction graphically.	Weatherzone Stormtracker allows you to view different elements of current weather on the one display.

	Each full-barb represents 10 knots (nautical miles per hour), a half-barb 5 knots and a flag 50 knots. Calm conditions are indicated by a dot only. 1 knot is equal to around 1.9km/h.		Lightning strikes are displayed as crosses and fade from white (current) to red (30 minutes ago) to blue (60 minutes ago).

	In the examples to the left the first indicates a 5 knot wind from the south-west, the second a 15 knot wind from the west-north-west, the third a 45 knot easterly and the fourth a 65 knot northerly.			Surface observations are displayed as a 'rose' with temperature, dew point and relative humidity down the left-hand side and rainfall since 9am, pressure and location name displayed down the right-hand side.

		Temperatures fade in colour from blue (cold) to red (warm) and dew points fade in colour from blue (moist) to red (dry).
