Beaufort Javascript

[Admin]

This Javascript displays the description of the wind using Beaufort Force nomenclature. As written, it utilizes Miles Per Hour. It can be easily modified for other units by changing the threshhold criteria for those units, which are widely published.


<SCRIPT LANGUAGE="javascript">

var force = Math.max(<!--windSpeed-->,<!--wind10avg-->)

if (force <= 1.0)
 {beau = "Calm; smoke rises vertically"}
if (force >= 1.0)
 {beau = "Smoke drift indicates wind direction; vanes do not move."}
if (force >= 4.0)
 {beau = "Wind felt on face; leaves rustle; wind vanes begin to move."}
if (force >= 8)
 {beau = "Leaves, small twigs in constant motion; light flags extended."}
if (force >= 13)
 {beau = "Dust, leaves, and loose paper raised up; small branches move; flags flap."}
if (force >= 19)
 {beau = "Small trees in leaf begin to sway"}
if (force >= 25)
 {beau = "Large tree branches bend; whistling in power lines; umbrella unwieldy."}
if (force >= 32)
 {beau = "Whole trees in motion; resistance felt in walking against wind."}
if (force >= 39)
 {beau = "Twigs and small branches broken off trees; walking into wind difficult; cars veer on road."}
if (force >= 47)
 {beau = "Slight structural damage occurs; slate blown from roofs; signs and antennae blow down."}
if (force >= 55)
 {beau = "Trees broken and uprooted; structural damage."}
if (force >= 64)
 {beau = "Widespread damage."}
if (force >= 75)
 {beau = "Severe and extensive damage; violence and destruction."}
