Weather is the day-to-day or hour-to-hour change in the atmosphere. Weather includes wind, lightning, storms, hurricanes, tornadoes (also known as twisters), rain, hail, snow, and lots more. Energy from the Sun affects the weather too. Climate tells us what kinds of weather usually happen in an area at different times of the year. Changes in weather can affect our mood and life. We wear different clothes and do different things in different weather conditions. We choose different foods in different seasons.
