Key points to remember:
- The atmosphere is a layer of air around Earth. Changes in the air in the atmosphere determine our weather.
- Air takes up space. (We see it when a balloon inflates or a tire is filled with air.)
- Properties of air include temperature (how hot or cold the air is), humidity (the amount of moisture in the air), and air pressure (the force air puts on objects).
- Clouds form when warm, humid air cools and condenses into water droplets. These droplets attach to dust in the air.
- There are three main types of clouds: cirrus (thin, wispy clouds high in the atmosphere), cumulus (puffy clouds in the middle of the atmosphere)), stratus (gray clouds that are low in the atmosphere).
- Different types of clouds bring different types of weather.
- Meteorologists (scientists who study the weather) use tools to collect data about weather conditions. Thermometer - air temperature, barometer - air pressure, anemometer - wind speed, wind vane - wind direction, rain gauge - precipitation, hygrometer - humidity.
- By observing weather conditions we can identify patterns that help us to predict the weather.
- Wind or air pressure dropping are indicators that a storm is coming.
- Severe weather includes blizzards, hurricanes, thunderstorms, and tornadoes.
