A SPECI observation typically consists of how many sections?

A SPECI observation is a type of aviation weather report that is issued when there are significant changes in weather conditions at an airport or reporting station. The structure of a SPECI observation comprises two main sections: the header and the body.

The first section, or header, includes general information such as the location of the observation, time of observation, and the type of report. It essentially sets the stage for what follows. The second section, or body, provides detailed information about current weather conditions, including visibility, wind direction and speed, cloud cover, temperature, dew point, and significant weather phenomena.

This two-section format allows for clear and concise communication of critical weather information to pilots and air traffic controllers, which is essential for flight operations and safety. Understanding the structure of a SPECI observation helps surface weather observers effectively relay crucial meteorological data.
