36. Reviewing Main Ideas 1
What is weather?
Factors that determine weather include air pressure, wind, temperature, and the amount of moisture in the air.
More water vapor can be present in warm air than in cold air. Water vapor condenses when the dew point is reached. Clouds are formed when warm, moist air rises and cools to its dew point.

37. Reviewing Main Ideas 1
What is weather?
Rain, hail, sleet, and snow are types of precipitation.

38. Reviewing Main Ideas 2
Weather Patterns
Fronts form when air masses with different characteristics meet. Types of fronts include cold, warm, occluded, and stationary fronts.
High atmospheric pressure at Earth’s surface usually means good weather. Cloudy and stormy weather occurs under low pressure.
Tornadoes, thunderstorms, hurricanes, and blizzards are examples of severe weather.

39. Reviewing Main Ideas 3
Weather Forecasts
Meteorologists use information from radar, satellites, computers, and other weather instruments to forecast the weather.
Weather maps include information about temperature and air pressure. Station models indicate weather at a particular location.
