What does the abbreviation 2518+06 in a Winds Aloft Forecast indicate?

The abbreviation 2518+06 in a Winds Aloft Forecast breaks down into two key components: the wind direction and speed, followed by temperature information. The first part, 2518, indicates winds coming from a direction of 251 degrees at a speed of 18 knots. The “+” sign signifies that the temperature is above zero, and the “06” indicates that the temperature is 6 degrees Celsius.

Understanding these conventions is crucial for pilots when interpreting weather data, as they affect flight planning and in-flight performance. Knowing the wind direction helps pilots anticipate how it might affect their flight path, and wind speed informs them of potential turbulence. Additionally, recognizing temperature trends is important for understanding atmospheric conditions that can influence aircraft performance.

The other options introduce different interpretations of the wind direction and speed, as well as the temperature scale (Celsius vs. Fahrenheit), which do not align with the standard format of these forecasts. Thus, focusing on the proper interpretation of the abbreviation provides a clear understanding of the weather conditions being reported.
