Signs and symptoms. Eye floaters are suspended in the vitreous humour, the thick fluid or gel that fills the eye. The vitreous humour, or vitreous body, is a jelly-like, transparent substance that fills a majority of the eye.

Wind speed is a measurement of the speed of movement of the air, and is typically reported in miles per hour (mph) or kilometers per hour (kph). Reports for maritime and aeronautical operations may use those or knots (nautical miles per hour).
The Beaufort scale /ËboÊfÉrt/ is an empirical measure that relates wind speed to observed conditions at sea or on land.Its full name is the Beaufort wind force scale, although it is a measure of wind speed and not of force in the scientific senses.here v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number.
