Sea squall
Sitting on the beach listening to the muffled sound of waves gently lapping the seashore... what could go wrong? Suddenly, a squall whips up out of nowhere, swaying the palm tree, which yields to this force of nature - the wind sock tells of gale force winds of 15 knots or more. An intrepid seagull seizes the moment and flies headlong into the strong wind ... as the lone eyewitness takes it all in.
So what exactly does the windsock tell us?
- The shape of the windsock is designed to catch the wind, and as it fills, the sock will point directly away from the wind source. In the artwork, the wind is blowing from right to left
- The greater the wind speed, the more the sock will fill out and stretch. This amount of inflation gives a visual cue not only of the direction of the wind but also of the wind’s strength.
- For example, for winds of a strong or severe gale (15+ knots or 30+ mph or 48+ km/h) force: The windsock will extend fully, even nearly horizontal, indicating very strong winds.
Comments
0 (Calm) – Wind speed less than 1 knot (0–1 mph); smoke rises vertically.
1 (Light Air) – 1-3 knots (1-3 mph); smoke drifts but wind is not felt.
2 (Light Breeze) – 4-6 knots (4-7 mph); wind felt on face, rustles leaves.
3 (Gentle Breeze) – 7-10 knots (8-12 mph); leaves and small twigs in motion.
4 (Moderate Breeze) – 11-16 knots (13-18 mph); small branches move, raises dust.
5 (Fresh Breeze) – 17-21 knots (19-24 mph); small trees sway, waves form on water.
6 (Strong Breeze) – 22-27 knots (25-31 mph); large branches sway, umbrellas hard to use.
7 (Near Gale) – 28-33 knots (32-38 mph); whole trees sway, walking against wind is difficult.
8 (Gale) – 34-40 knots (39-46 mph); twigs break, difficult to walk.
9 (Strong Gale) – 41-47 knots (47-54 mph); minor structural damage, shingles blown off roofs.
10 (Storm) – 48-55 knots (55-63 mph); trees uprooted, structural damage.
11 (Violent Storm) – 56-63 knots (64-72 mph); widespread damage, rare inland.
12 (Hurricane) – 64+ knots (73+ mph); extreme destruction, large waves at sea.
This scale is still widely used in meteorology, marine navigation, and weather forecasting
The tree looks like a flamenco dancer when she throws her head back...the kind of honest pride in her art form which runs in her blood...
