Weather Questions The video segment and reading gave us some things to think about and may have raised some questions. You might have some other questions about weather that we experience where we live. Everyone will write 3 or 4 questions you have about weather.

Weather Questions Share your questions with your group. Each group will share ONE question with the class.

METEOROLOGY The word meteorology literally means the study of meteors. That may sound like it doesn’t have much to do with weather, but in ancient Greece, anything that fell from the sky was considered a meteor, whether it was what we know as a meteor today, rain, snow, or hail.

METEOROLOGY The scientific study of Earth’s weather is called meteorology. A person who studies the causes and effects of Earth’s weather is a meteorologist.

METEOROLOGY Today meteorology includes only the study of weather. Planetary scientists study meteors. Some meteorologists study weather in order to make predictions or forecasts to let people know what kind of weather to expect the next day or the next week.

FORECASTS Who would use a weather forecast and what decisions might they make based on them? –How people dress for the day –Travel plans (air travel) –Health issues (allergies, colds) –Business people (umbrellas, snow gear, swimsuits) –Vacation or recreation plans (camping, sailing, picnics, mini-golf ) –Gardening, Farming (spring planting, harvesting)
