How would a temperature of 10 degrees Celsius with a missing dew point be transmitted?

In aviation weather reporting, particularly within the Limited Aviation Weather Reporting System (LAWRS), temperatures are usually expressed in degrees Celsius. When a dew point is missing from the report, specific conventions are used to indicate this absence.

The correct representation for a temperature of 10 degrees Celsius with a missing dew point is shown as "10/." This format designates the temperature followed by a forward slash, which signifies that no dew point data is available. The convention is important for ensuring that pilots and meteorologists can correctly interpret weather data, as the dew point is crucial for understanding humidity and potential weather conditions.

The other variations presented, while they might seem relevant, do not conform to the established reporting standards. The use of double slashes or terms like "Nil" or "0" could lead to confusion and misinterpretation, as they do not accurately communicate the lack of dew point information in a standard way. Proper formatting is essential for clear communication of weather reports, especially in aviation, where precise data can significantly impact flight safety.
