Encarta® Encyclopedia defines weather
as the state of the atmosphere at a particular time and place. The elements
of weather include temperature, humidity, cloudiness, precipitation, wind
and pressure. These elements coalesce into various weather systems such
as hurricanes, high and low pressure, thunderstorms, etc. All weather systems
have well-defined cycles and structural features and are governed by the
laws of heat and motion.
Essential Understandings:
-
Weather differs from climate.
Climate is the weather that a particular region experiences over a long
period of time; it includes the averages and variations of all weather
elements.
-
Temperature is a measure of the
degree of hotness of air.
-
Humidity is a measure of the
amount of water vapor in the air.
-
Most clouds and almost all precipitation
are produced by the cooling of air as it rises.
-
Precipitation is produced when
the droplets and crystals in clouds grow large enough to fall to the ground.
-
Wind is the horizontal movement
of air. It is named for the direction from which it comes.
-
Pressure is the force of the
air on a given surface divided by the area of that surface.
