Station Model - Present Weather and Visibility

Present Weather and Visibility

To the left of the cloud shape in the center of the station model is the symbol depicting present weather. The present weather symbol depicts the current weather which normally is obstructing the visibility at the time of observation. The visibility itself is shown as a number, in statute miles in the United States and meters elsewhere, describing how far the observer can see at that time. This number is located to the left of the present weather symbol. For pilots, knowledge of the horizontal visibility helps determine if they are flying through instrument meteorological conditions, such as foggy or smokey conditions, as well as areas of intense precipitation. Present weather depicted with the station model can include:

  • Dust
  • Fog
  • Haze
  • Ocean spray
  • Precipitation
  • Sand
  • Smoke
  • Thunderstorms
  • Volcanic ash

Famous quotes containing the words present, weather and/or visibility:

    The new man is born too old to tolerate the new world. The present conditions of life have not yet erased the traces of the past. We run too fast, but we still do not move enough.... He looks but he does not contemplate, he sees but he does not think. He runs away from time, which is made of thought, and yet all he can feel is his own time, the present.
    Eugenio Montale (1896–1981)

    When the weather suits you not,
    Try smiling;
    When your coffee isn’t hot,
    Try smiling;
    Unknown. Try Smiling (l. 1–4)

    My children have taught me things. Things I thought I knew. The most profound wisdom they have given me is a respect for human vulnerability. I have known that people are resilient, but I didn’t appreciate how fragile they are. Until children learn to hide their feelings, you read them in their faces, gestures, and postures. The sheer visibility of shyness, pain, and rejection let me recognize and remember them.
    Shirley Nelson Garner (20th century)
