Well the first problem is that those spells in the Fantasy section here on SOM do not work and will not work no matter how often you do them. That's why they are in the Fantasy section...because they aren't real.
Nor is it possible to control the weather, although there are ways to work with the weather to achieve some small results.
You might want to do some reading on how and why magic works and what is and is not possible. I'd suggest the book "Spells and How They Work" by Janet and Stewart Farrar and "Modern Magick" by Donald Kraig.
