2023年6月13日 · Time zone offsets are identified as -12 UTC through 0 to +12 UTC, with the minus values signifying time "before" or ahead of prime meridian (which is the Western Hemisphere). At the meeting of the -12 and +12 time zones is the International Date Line.

The most common Z times you will come across are 0Z (late afternoon in US), 18Z (near noon in US), 12Z (morning in US) and 6Z (near midnight in US). It is a wise habit to look at the time stamp first on an image before interpretation. This prevents the unwanted task of interpreting old data.

This time is significant because it represents the start of a new forecast cycle, providing meteorologists with fresh data for analysis and forecasting purposes.

The 12z maps are produced at 13z using the 06z NAM 6-hour forecast as a first guess for the objective analysis. If the 18z or 06z NAM runs are unavailable, a first guess from the 12-hour foreacst of the 00z or 12z NAM is used.
