You can't get on ubuntu. That's and .iso file, and it won't work yet.
It's a large file, because it is an OS.
It only runs in a Linux environment. If you want you can try cygwin, but idk how to do that.
That's why I said, get VirtualBox, it gives a separate environment for side OSs.
So you must install VirtualBox first, then download Ubuntu (don't do it while you are installing, it cuts you form the internet), then you create an OS, and then select it, and click Start. It will ask you to create a hard drive (choose dynamically expanding and the default values), and where you want the disk from (iso is a disk image file, but you don't need a disk) so click the folder thing that you use to browse. Then select where you downloaded Ubuntu. Some other stuff will happen, and then it will ask you if you want to try or install. Click install.
That'll take about 15-30 mins.
Then it will ask if you want to restart. Do that.
Let it do it's thing, and open VirtualBox again (most likely it's just minimized), and click settings (next to Start). Then click system. Under "Boot Order" select "Hard Disk" and move it to the top using the arrows next to the box, or unselect the other options.
Go back to Ubuntu (should already be open), and click the power looking button in the top right corner of Ubuntu itself, not the red x
Then re-open ubuntu in VirtualBox (green start arrow if you don't remember), if it prompts you to Try or install = again, then go up to the (1) and try the option you didn't do.
The rest of the tutorial will be typed when I get back from school. This should occupy 1 hour out of your day or so. You can explore on Firefox, download a few things, go on the forums, try it out a bit, get familiar.
If you DO want to continue, and you feel you can do this on your own, you can go here: http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Tropical_cyclones/Tracks
NOTE: YOU CAN'T COPY FROM WINDOWS TO UBUNTU: OPEN THIS PAGE IN UBUNTU IF YOU ARE GOING TO DO THE ABOVE.
It's mostly self explanatory, but a few things aren't.
