Meteorologists need to use the Meteorologists need to use the same time everywhere since we same time everywhere since we exchange data globally exchange data globally
Meteorologists use the local standard time at the Meteorologists use the local standard time at the Greenwich Meridian (0 Greenwich Meridian (0 longitude, near London). longitude, near London). Many Names Many Names Greenwich Mean Time (GMT) Universal Coordinated Time (UTC) Zula Time (Z) Generally, UTC is used today, but some groups (like the NWS) often use Z and GMT.
How to convert. UTC is LATER than Pacific time How to convert. UTC is LATER than Pacific time since the Greenwich Meridian is to our east since the Greenwich Meridian is to our east UTC = PST + 8 hr UTC = PDT + 7 hr Uses a 24 hr clock First, convert our time to 24 hr clock Then, add 7 or 8 hr depending on whether we are in daylight or standard times. If the sum is equal to or greater than 24 hr, subtract 24h and add one day.
Examples 4 AM PDT 1 October: 4 AM become O4 Add 7 hr = 11 UTC 1 October 4 PM PDT 1 October 4 PM become 16 Add 7 hr = 23 UTC 1 October 6 PM PDT 1 October 6 PM becomes 18 18 + 7= 25 UTC. Need to subtract 24 and becomes 01 UTC 2 October Your test: 10 PM PDT 1 October is what in UTC? You need to be able to do this conversion or you won t be able to understand weather maps.
