CHARTING WEATHER PATTERNS
Weather is a very personal phenomenon. We want to
know if it is rainy or sunny to help us decide what to wear. A farmer or
fisherman needs to know if a storm will influence their decision to
harvest or fish. Before a plane goes into the air, the pilot must check
to see if the weather conditions could prevent his flight from
continuing. Problems in communication, especially wireless transmission,
can also be caused by weather patterns.
Do not confuse weather with the climate.
Climates can be considered the average weather conditions over a long
period of time. The climate is influenced by latitude, land and water
distribution, altitude, land barrier, air movement, ocean currents,
permanent storm areas, temperature, humidity, precipitation, cloud
cover, high and low pressure centers, and other weather phenomena.
Climate defines the seasons for each geographic region. For example,
spring in the mid latitudes brings mild climate, but in the low
latitudes spring brings little change in the weather.
