METEOROLOGY
How has technology
improved our ability to
predict weather
In earlier times, weather observations from
faraway places could not be collected in one place
soon after they were made. The only way of
predicting the weather was observation, and local
experiences. In 1870 the weather surface used the
telegraph to gather weather observations from
weather stations. Through the 20th century,
meteorologist developed even better tools for
observing and predicting weather. Special
instruments measure weather in the atmosphere
far above the ground. Satellites send back
images. Computers handle enormous amounts of
observational data and make billions of
computations quickly. Also, meteorologist use
instruments carried by balloons, satellites, and
weather stations around the world.
Why is weather
Weather is important in our life. It affects what
prediction important
clothes we wear, our choices of activities, and it
can also affect our moods. Weather is due to 4
atmospheric factors: heat energy, air pressure,
winds, and moisture. Changes in these factors
determine the kind of weather you experience,
from fierce winds to blinding snow, to calm of a
warm summer day.
What is the difference Weather is the condition of the atmosphere at a
between weather and
particular time and place. Climate is the average
climate
weather conditions in a certain area over a long
period of time.
Where do meteorologist Meteorologist get weather information from local
get weather information weather observers, instruments carried by
balloons, satellites, and weather stations around
the world.
What is a weather map A weather map is a snapshot of conditions at a
particular time over a large area. They utilize
standard symbols to show fronts, areas of high
and low pressure, types of precipitation and
temperatures.
