and storms will result. A warm front
forms when a cold front retreats. The
less dense warm air rises over the cooler
air. A warm front generally produces
precipitation over a large area and may
cause violent weather.
20. Computer models show possible
weather conditions for several days.
Scientists can manipulate details such
as temperature and air pressure to show
possible weather forecasts. These models must be carefully interpreted then by
the meteorologists.
21. Weather stations around the world
gather data and send it to collection centers. Weather centers around the world
exchange this information.
22. Data from weather collection centers is
transferred onto weather maps. Weather
maps use colors and symbols that can
be understood in any language to communicate data.

When air pressure differences are
small, air remains relatively stationary or moves slowly over a uniform
region, and it takes on the characteristic temperature and humidity of the
region, thus creating an air mass.
18. Scientists use computers to solve
mathematical equations that describe
the behavior of the atmosphere, store
weather data, and store weather
records for quick retrieval.
19. When a cold air mass overtakes and lifts
a warm air mass, a cold front develops.
If the warm air is moist, clouds will form

24. Answers may vary. Sample answer:
Avoid touching metal. Stay low to the
ground, and avoid tall objects, such as
lone trees, that may attract lightning.
Get into a car or into another shelter, if
possible, to avoid being struck by winddriven objects.
25. Answers may vary. Sample answer: If
there is not enough water to use for irrigation, and if there are cumulus clouds,
then seeding the clouds might trigger
rain. This would be a possible short-term
solution until the drought breaks.
