By . Ruchita. . Aggarwal. . Meteorologist . A meteorologist is a person who studies meteorology. Meteorology is the study of the changes in temperature, air pressure, moisture, and wind direction in the troposphere. It is basically the science of the atmosphere. It gives us the basic idea of the forces that cause weather and climate. As well as how human activities can affect climate, for example pollutants in the atmosphere.
