Interpreting METAR and TAF Reports
METAR Reports
METAR (Meteorological Terminal Aviation Routine Weather Report) reports provide current weather conditions at an airport. They include information on wind, visibility, temperature, dew point, pressure, clouds, and precipitation.
TAF Reports
TAF (Terminal Aerodrome Forecast) reports predict weather conditions for the next 24 to 30 hours. They include similar information as METAR reports, but with a focus on expected changes.
Understanding METAR and TAF Codes
METAR and TAF reports use coded abbreviations to convey a wealth of information. Understanding these codes is crucial for interpreting the reports accurately.
Location and Time
The first part of a METAR or TAF report identifies the airport location and the time of observation or forecast issuance.
Wind
Wind information includes the direction, speed, and any gusts. Wind direction is reported in degrees relative to true north, while speed is reported in knots.
Visibility
Visibility refers to the distance at which objects can be clearly seen. It is reported in statute miles or kilometers.
Clouds
Cloud information includes the type, altitude, and amount of clouds present. Cloud types are classified according to their appearance, while altitude is reported in feet above ground level. The amount of clouds is expressed in oktas (eighths of the sky covered).
| Cloud Type | Abbreviation |
|---|---|
| Clear | CLR |
| Scattered | SCT |
| Broken | BKN |
| Overcast | OVC |
Precipitation
Precipitation information includes the type and intensity of any precipitation occurring. The type of precipitation can be rain, snow, hail, or a combination of these. The intensity can be light, moderate, or heavy.
Temperature and Dew Point
Temperature and dew point are reported in degrees Celsius or Fahrenheit. Temperature measures the actual air temperature, while dew point indicates the temperature at which water vapor in the air condenses.
Pressure
Pressure is reported in inches of mercury (inHg) or millibars (mb). It is an indicator of atmospheric weight and can affect aircraft performance.
Understanding Regional Reports
Regional reports provide a comprehensive overview of weather conditions within specific regions. Here’s how to interpret and use them:
1. **Location:** The report includes the location name and its associated Regional Forecast Center (RFC).
2. **Period Covered:** The report covers a period of 24 to 72 hours, depending on the region.
3. **Weather Type:** Regional reports describe the dominant weather types expected, such as rain, snow, or clear skies.
4. **Temperature and Wind:** The report provides the expected temperature range and wind conditions, including speed and direction.
5. **Precipitation and Fog:** Information on precipitation type, intensity, and duration is included, along with visibility conditions due to fog.
6. **Specific Details:** Regional reports often include additional details tailored to the local area or aviation operations. This section may provide:
| Specific Details | |
