There are a lot of variables involved in what a meteorologist gets paid. Markets are a major factor, as the larger the size of the area the television station covers the more viewers a station potentially has. More viewers will allow a station to charge more for advertising, and can then offer higher meteorologist salaries. Experience also plays a part. A meteorologist just getting out of university will not make the same salary as a meteorologist that has ten years of experience, even if the job is the same.
Once a meteorologist gets a few years of experience under their belt, they'll get opportunities to either move up in position or market size. That is when a meteorologist's salary starts to increase. However, the number of higher paying spots is much less than the number of lower paying spots, since everyone wants them.
