Today, meteorologists use complicated mathematical equations to help predict the weather as part of a process known as numerical forecasting. Numerical forecasting requires powerful supercomputers and tons of observational data from land, sea, and air weather stations around the world.

What do meteorologists do?

Meteorologists are observers and researchers. They note the physical conditions of the atmosphere above them, and they study maps, satellite data, and radar information. They also compare various kinds of weather data from local, regional, and global sources.

How do meteorologist determine the weather?

Meteorologists are able to predict the changes in weather patterns by using several different tools. ... For example, weather balloons are special balloons that have a weather pack on them that measures temperature, air pressure, wind speed, and wind direction in all the layers of the troposphere.
