Re: Some Department of Commerce weather alert systems use Fortran
There aren't that many COBOL and Fortran programmers left, and no one is learning those languages these days
Also worth noting that Fortran tends to be taught as the programming language of choice to physics undergraduates - apparently it's quite popular in that area - it has an international standards body and is targeted at scientists. It is also pretty damn fast (http://www.hindawi.com/journals/sp/2014/870146/abs/) and, to emphasise a point made above, it is used for large numerical calculations (http://www.moreisdifferent.com/2015/07/16/why-physicsts-still-use-fortran/)
In the field of high performance computing (HPC), of which large scale numerical simulation is a subset, there are only two languages in use today — C/C++ and “modern Fortran” (Fortran 90/95/03/08).
