Instructions for Animations of Composite West Coast Overview Weather Maps
with Visible Images
- In the "SELECT" area, select the number of days to appear in the
animation (the default is highlighted in gray).
- Press the "Build Animation" button.
If it is still relatively early in the current day (Pacific time), so
that only one or at most two maps with visible satellite images have
become available, the animation doesn't count them as one full day.
Instead, they are added to the previous day's maps and the result
is counted as one day of animation.
Missing images are automatically skipped and up to three are listed.
To step through animations frame-by-frame, first press the
"Stop" button ("*"), then press the "Next" button ("|>")
repeatedly to advance frames one at a time. Similarly, press the
"Back" button ("|<") to step backward one frame at a time.
To restart the animation after stopping it, press the "Restart"
The WWWeb server (virga.sfsu.edu) receives data to construct a
sea-level composite West Coast overview weather maps every 3 hours, within
2 hours after the map analysis time (from the 00Z North American model
[NAM] runs) or within 1 hour (from the 15Z, 18Z, 21Z, and 03Z
Rapid Update Cycle [RUC] model runs).
To update an animation to add any newly created map(s), simply press
the "Build Animation" button again.
- If the animation does not seem to be working correctly, check
your computer's date/time--the animation depends on its
simpley "scripting" is enabled. (In Microsoft's Internet
Explorer, try looking in the "Web Browser" section of Preferences,
under "Web Content" or "Advanced".)
- If you resize the browser window you might need to press the
Reload button or choose Reload from the View menu.
