After a long struggle to find the best software to make these animations, DivX won the battle (by far!). The image quality is not as good as jpg, but still fair, and even large files will run smoothly. You'll need the DivX codec to view the movies; it is free and can be downloaded here.


June 18 2004: Lee wave activity. A strong flow from the south is forced over the Alaska Range, giving lots of lee wave activity. The time lapse is from 8 pm in the evening till 2 am - that's as dark as it gets up here this time of year. 20 sec. between frames, 1080 frames (6 hours), 720x480, 5305KB.


June 18 2004: A crop of the above movie, showing some detail in the flow. I especially noticed how clearly you can see the air flowing 'downhill' from the wavecrests due to the perspective. 20 sec. between frames, 300 frames (1 hour 40 min.), 600x400, 1472KB.



July 4 2004: Dense morning fog looks uniformly grey and boring when you're standing in the middle of it. It's more fun to watch after speeding things up a little. 20 sec. between frames, 720 frames (3 hours), 720x480, 4682KB.



July 21 2004: This summer was poor for doing cloud movies here in Alaska where we had a record fire season. Over 6.7 million acres went up in flames, and Fairbanks was shrouded in smoke for weeks. In this movie the wind was favorable for visibility in Fairbanks, and we could see the smoke plume from one of the smaller fires southwest of town. 10 sec. between frames, 1080 frames (3 hours), 720x480, 6221KB.


September 14 2004: Low clouds forming and drifting over the valley. Fall colors are out and would have looked nice with some sunshine, but not this morning. 15 sec. between frames, 1080 frames (4 hours 30 min.), 720x480, 8080KB.



September 24 2004: Fall colors were still out, and since it was clear before sunrise I hoped to catch them this time. It proved to be the last chance; the very next day most leaves were on the ground! Low clouds rolled in and mostly spoiled it, but the sun peaks through some holes towards the end and gives you a glimpse. It also shines at Ester Dome for a while, revealing that there's already snow on the ground up there. 15 sec. between frames, 960 frames, (4 hours), 720x480, 6270KB.


September 24 2004: In the afternoon light snow showers started rolling in, and here you can see why there's snow on Ester Dome (but not here). Whereas only one shower makes it here to campus, you'll see something like 10 showers sweeping across Ester Dome. I don't quite understand how that works, but see for yourself.  10 sec. between frames, 1543 frames (~4 hours 15 min.), 720x480, 9730KB.



November 17 2004: We've sure seen a lot of clouds this fall, more than I like. They've shed a bit of snow now and then, and here it clears (somewhat) after a new dusting. Since there's no wind, every branch is covered with snow which does look nice. The clouds display lots of wave activity. 15 sec. between frames, 1055 frames (~4 hours 30 min.), 720x480, 6539KB.
