Meteorology opens up a lot of career options. The most obvious is probably a weatherperson on television, but you could also work for national weather services, become a storm chaser, cover weather-related articles for newspapers and magazines, write books about weather, become a professor who teaches meteorology, and so on.
There are several fields in meteorology. Atmospheric physics that studies physics as it relates to atmospheric conditions. The scientific discipline that deals with the chemical make up and properties of the atmosphere is atmospheric chemistry. Hydrology deals with the water and moisture aspects of the air in the atmosphere and what it affects.
Not only can a person with a meteorology degree become a meteorologist, someone who announces the weather on local or national news, but in today's society someone with a degree in meteorology can work in the military predicting the weather before operations ensue. Meteorologists can also trace and track natural disasters, like tornadoes and hurricanes.
Many meteorologists work in airline central-command posts and assist the airline in making short-term plans. Some work for agri-businesses to time the harvest so that the crop is the safest from rain or cold. Others forecast local weather and advise cities. A few chase tornadoes on TV and a few are on the news every night.
