Radar/Satellite Animator Symbols
Rainfall Intensity
light | heavy |
The intensity of rainfall detected by weather radars is indicated using the above scale.
Doppler Wind
90km/h towards | 90km/h away |
On Doppler radar images the radial component of the movement of particles in the air is indicated using the above scale.
Lightning Events
Lightning strikes are displayed as crosses (ground events) or squares (cloud events) and fade from white (current) to red (30 minutes ago) to blue (60 minutes ago). Positive strikes appear as diagonal crosses.
Accumulated Rainfall (since 9am)
Rainfall since 9am local time is displayed with coloured dots.
Observations Rose
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).
How to Read a Wind Barb
A wind barb is a compact means of representing both wind speed and direction graphically.
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.
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.
