    Sign for wind speed

    請問風速快慢的符號是怎樣畫的?

    要圖+注釋(如5m/s等)

    Wind speed symbols are wind barbs which show both speed and direction on Weather Station Models as in the diagram below.

    Wind speed is in units of knots ( 1knot=1.15miles/hour)

    圖片參考:http://z.about.com/d/weather/1/5/m/-/-/-/windbarbs...

    (Alternatively :Wind = The air is nearly always in motion, and this is felt as wind.Units: Meter per second for wind)

    Visibility 的單位是什麼?

    Visibility is the greatest distance at which prominent objects, such as buildings, mountains, trees, and other objects are clearly seen and identified by unaided, normal eyes. It is also called horizontal visibility.

    Units: Kilometer
