humidity. Meteorologists study weather by taking measurements of these conditions. The
National Weather Service collects the measurements and records them on maps using a
combination of symbols. These symbols form a station model which shows the weather
conditions at one specific location. Some conditions shown on a model are: wind speed and
direction, barometric pressure, change in barometric pressure in the last three hours, fraction of
sky covered by clouds, dew point temperature, type of precipitation and temperature.
With the information from a station model, meteorologist scan predict the weather. For
example, meteorologists know that high pressure is generally associated with fair weather and
low pressure is usually associated with cloudy weather. If the barometric pressure is rising,
weather is probably improving. The dew point indicates the temperature air is saturated and
condensation occurs. These measurements, along with others, help meteorologists predict what
kind of weather may be ahead.
In this lab you will explore weather data collected over several days at stations in a certain
region of the US. Then you will make a prediction about the weather at those stations. When
making your predictions, remember that weather systems generally move from west to east.
Use the data from the westernmost station model in a region to predict the weather for the
region’s other stations.
Be sure to be familiar with the
Station Model Key before
starting.
