  11. ELO Interpret wind information

  12. METAR KOZR 121455Z 18005KT • SURFACE WIND • Wind direction in reference to TRUE north and is reported to the nearest 10°. • Wind speed is a 2 minute average reported to the nearest knot . VRB is used when speed is less than or equal to 6 knots. Example: VRB05KT • Calm wind is shown as 00000KT. Property of Lear Siegler

  13. METAR KOZR 121455Z 20015KT180V260 • SURFACE WIND • Gust - fluctuations in wind speed of 10kts or more between peaks and lulls. Example: 27015G25KT • Varying. A “V” is used when wind varies 60° or more and the wind is greater than 6KTS • Peak Wind. Peak wind is reported in remarks when instantaneous speed is greater than 25 knots. Example: PK WND 22030/15 Property of Lear Siegler

  16. ELO Interpret visibility information

  17. METAR KOZR 121455Z 18005KT 1/2SM • PREVAILING VISIBILITY • Visibility is the greatest horizontal distance specified objects can be seen and identified or its equivalent derived from instrumental measurements. Reported in miles and fractions of miles. • Prevailing visibility is the greatest horizontal distance that specified objects can be seen over at least one-half of the horizon, not necessarily continuous. • Variable visibility is explained in the remarks section • Automated stations use an “M” to indicate “less than.” For example, M 1/4SM means less than one-quarter statue mile visibility.
