A day in the life of clouds

[fractonimbus]

Made a time lapse movie of my webcam images today. It's amazing how many different directions clouds can move in a short time.

The movie is here: http://www.dcnicholls.com/wx/temp.html (really crappy page - I will recode it and it may get a more permanent URL in due course).

It's a large file - 11Mb - and as the server is in Oz, it may be jerky and take a while to download the first time for some of you. But it will run at full speed when you replay it.

I used Yawcam to generate the images every 30 seconds. The only quirk is that the Logitech drivers sometimes oscillate in gain at certain combinations of contrast and light level. The brief green flash near the end is the stupid "I'm on" LED on the camera (now masked). The camera (a Quickcam Communicate STX) does quite a good job considering it's taped to the inside of a double glazed window!

Good one

Exceptionally good video of clouds!

Mind if I use it for a nautical meteorology course? I'll be happy to provide credits and the like.

[fractonimbus]

Yes, by all means use it. Glad you find it useful.

GDay all

Finally, another user trying their hand at timelapse.
I have been trying to get it right for a while now.
The camera is Olympus and I have Still - previous 4hr and yesterday 24hr.
The images and timelapse all happen without my doing anything which is a good thing
as I would probably get it screwed up.
I like them now and hope my visitors will too.

Love the timelapse images.

How about one of you smart people adding timelapse wind direction, temperature and barometric pressure etc. to the image?

That would be interesting but I already have too many projects on the go

We had a weather front come over us a few days ago. You could see it coming by the change in cloud formation. As it arrived there were huge changes in wind direction, temperature and humidity.

[Gina]

Yes, I've seen that sort of thing too. And you can see when a front has passed through in the night by a sudden change in temperature.

Something similar to what can be seen on this [link removed]...

Something similar to what can be seen on this page...

Very nice.... and it worked using IE

Ray, very nice but can I have it graphically please ??

Sorry but I do not understand what you mean by 'graphically'?

Additional information should have been provided...

First, the 500+ sequential images needed to produce the one day movie (at 1 minute interval) and the weather data (appearing on each images) are captured and saved by ImageSalsa (shareware) onto one of my computers.

Second, all the images are sequentially read and processed once a day by MovieSalsa (shareware) - the resulting movie or 'swf' file is then uploaded to my online server.

I probably could have used Windows scheduler to activate MovieSalsa and to upload the movie, but I have been using JP Software Take Command to do the work through the use of a powerful batch file - it gives me incredible control that Windows 'cmd' does not have, such as checks for errors, creates 2 types of movie formats ('SWF' and 'DivX'), FTP uploads the files to the server, moves the files on my computer (backup), deletes the processed files once the movies have been created, etc. - I had been using '4DOS' (also by JP Software but now deprecated) since my early years with Windows...

As for the web page display, I use two small inexpensive shareware scripts from TUFaT

Hi Ray, your images are very impressive.

What I was suggesting was for the data for say, wind speed, to be viewed as a graph the same way that Cumulus does but with a moving vertical line. The vertical line follows the time from the webcam image.

Not really my images, but the images from the webcam...

Dave, you asking for a lot are you not???

I still not too sure what you are hinting at...

You are now writing about gauges whereas before we were writing about webcam images...

If you are indeed writing about the graphic images produced by Cumulus, it is probably possible... The graph images produced by Cumulus would first have to be sequentially saved. Then that sequence of images compiled into a video file. The only situation would be to add a red vertical line to follow the time...
