A wind shift is accompanied by a cold frontal passage that began 30 minutes after the hour. How would this be coded?

The correct coding for a wind shift accompanied by a cold frontal passage that began 30 minutes after the hour is "WSHFT 30 FROPA." This code effectively communicates the occurrence of a wind shift (indicated by "WSHFT") followed by the time frame of 30 minutes after the hour (denoted by "30"), and then states the occurrence of the frontal passage ("FROPA").

The precedence of terms is important in weather reporting coding to ensure clarity and accurate interpretation. In this format, the wind shift is prioritized and immediately linked to the specific timing of the cold frontal passage, which helps meteorologists and other weather observers understand the sequence of changes in weather conditions.

Achieving clear communication in meteorological reporting is vital, as misinterpretation of coded messages can lead to confusion during critical weather monitoring and response actions. Thus, the arrangement in this choice efficiently conveys important timing and events in a standard format that is widely recognized in the field.
