As a WEATHER OBSERVER, you can either measure weather elements directly
or use Internet resources to acquire information collected by other observers.
Several sites on the Internet contain daily measurements which you can
print out for your records. One of the most useful types of information
is pictures
of cloud cover all over the world. These pictures enable you to see weather
patterns travel across the globe.
Local weather information
is important to every one and is up-dated frequently as conditions change.
Everyone is interested in the weather ! In addition to up-to-date pictures
of cloud cover, beautiful pictures of all different kinds and types of
weather
phenomena are available:
tornados
, hurricanes,
thunderstorms,
lightning,
snow
levels, rainfall amounts, cloud
types, and other
exciting weather elements. Much of the change in our
weather comes about as a result of the sun's influence on the earth's
upper
atmosphere. Energy from the sun arrives in the atmosphere
and changes its properties . The sun influences both weather here on earth
and space weather
between here and the sun. Visit the Internet to see where the energy comes
from to make changes in our atmosphere, when these changes happen and what
happens when the sun's energy reaches the Earth. See if, through daily
observations of Earth weather and space weather, you can make a connection
between the two! Welcome to the world of our Earth's WEATHER!
