This portion of my site features algorithms in a format for those writing weather programs. The algorithms are presented in Javascript source code, but if you know Java, C++, Pascal, or other similiar programming languages, you should be able to understand and adapt the code. Since this part is new, there may be some errors. I'll do my best to find them, but if you think you spot one please let me know.
