BR - Mist VRB = variable. AO1 - Automated Observation without precipitation discriminator (rain/snow) 1: Light Air: 1 to 3 mph: Direction of wind shown by smoke drift, not by wind vanes. If you don’t see any numbers it means the winds are calm. 08:13 AM Central | If it were AO1, there would be no precip sensor. NSW - No Significant Weather Little if any movement with flags. Air Dwpt M - In RVR listing indicates visibility less than lowest reportable sensor value (eg. Telling TAF Time The wind barbs types are shown in Fig. GR - Hail 20015KT 180V260 - If you see a report like this one, with the normal winds reported in the beginning and then 2 numbers separated by a "V" it means the winds are variable.

The RVR is the actual distance that you can see looking down the runway. Cloud height is measured in hundreds of feet ABOVE GROUND LEVEL or "AGL", so when we see in the example: This signifies that there is a scattered layer at 10,000 ft. Keep in mind that only these last two cloud designations (BKN and OVC) constitute ceiling. When no motion of air is detected, the wind shall be reported as calm. Leaves rustle and small twigs move. A02 means that the site is automated and HAS a precipitation sensor. Saratoga-Weather.org. A variable wind direction is.

This remark will contain the extremes of the wind directions, separated by “V.” In this example, 210V290 are reads, “wind direction varying between 210 and 290.” 7 METAR Wind Variability RMK - Remark 1 METAR. In section four we see that the visibility is greater than 10 km. Dec 21, 0752Z. Figure 2: Wind Barb Sample There are 19 regions plus a CONUS view. VRB - Variable wind direction when speed is less than or equal to 6 knots The wind speed data for the most recent 10 minutes shall be examined to evaluate the occurrence of gusts. 4 METAR. SM - Statute mile(s) The direction of the wind is variable from 180 to 260 degrees. SN - Snow A full list of special weather codes is available at the end of the page. In the third section we see that the winds are coming from 200 degrees and that the winds velocity is sustained at 13 knots, with gusts to 23 knots. In this tutorial we will cover the many aspects of disseminating the information contained in coded weather reports. The abbreviation "OVX" is unofficial but ADDS uses it here to indicate the sky is obscured which is the case when a METAR reports vertical visibility and no cloud information. The intensity of certain weather phenomena are reported by using the signs: "+","-", and by the absence of a sign. Wind speed (Knots) Label Effect on sea Effects on land; 1: Calm: Sea like a mirror: Calm. The direction of the wind is variable from 180 to 260 degrees. Date/ Time.

TKOF - Takeoff The first three digits 310 is the direction of the wind in degrees. For speeds equal to or greater than 100 KTS, 3 digits are used. Winds 190 at 18 knots, gusting to 33 knots. The first 3 digits of this number will always represent the heading that the wind is blowing from.
