Lewis Fry Richardson was a scientist who studied how to predict the weather. He came up with a way to measure the temperature and pressure of the air and how it changed over time. He looked at charts of the changes in temperature, pressure, and wind speed to help him predict the weather. He used math and a lot of calculations to come up with the best way to predict the weather. Today, many scientists and meteorologists use Richardson's discoveries and ideas to help them predict the weather.
