Performance Indicator 6.E.2B.1 – Weather Patterns and Conditions
Analyze and interpret data from weather conditions (including wind speed and direction, air temperature,
humidity, cloud types, and air pressure), weather maps, satellites, and radar to predict local weather patterns and
conditions.
Meteorologists can predict the weather by analyzing and interpreting data from observations and tools such as
current weather conditions, weather maps, satellites, and radar images.
Changes in the following weather conditions can indicate a change in the pattern of weather.
1. Wind _______________ is
measure of the percentage of water vapor in the air.
measured using an anemometer
Increased levels of humidity can be associated with
and indicates a change in
a high probability of precipitation.
atmospheric flow patterns.
2. Wind _______________ is
measured using a wind vane (also
known as a weather vane) and
indicates the direction of advancing
air masses.
3. _______________ is measured using a
thermometer. Changes in the air masses result in
changes in the temperature.
4. _______________ can be measured with sling
psychrometers or hygrometers. Humidity is a
5. ______________ is
measured with a barometer. A
rise in air pressure indicates fair
weather while a fall in pressure
indicates stormy weather
conditions advancing.
Basic shapes of clouds are associated with weather patterns.
6. _______________ clouds are high and wispy and signal fair weather or an approaching warm
front
7. _______________ clouds are puffy with flat bottoms and signal fair weather. However, when
they are darker, they may signal rain or thunderstorms, as they develop into _______________
clouds (thunderheads).
8. _______________ clouds are spread over a large area and are layered. As these clouds thicken
long periods of precipitation can occur over the area where the clouds are located.
Weather Maps
10. _______________ maps can help
predict weather patterns by indicating high or
low pressure systems (isobars), movement of
air masses and fronts, or temperature ranges
(isotherms).

11.
_______________ images are used for
seeing cloud patterns and movements.
a. For example, hurricane clouds and movement can be
observed using satellite images.
Radar
12. Radar
a. _______________ images can be used to detect cloud cover, rainfall, storm location or intensity, and
cloud movement, as well as the potential for severe weather (for example, hurricanes or tornadoes).
Extended Knowledge
_______________ models from specific locations provide information that can also be used to predict
weather patterns. Information found on a station model can include cloud cover, temperature (85°F), wind
direction and speed, precipitation (* - snow, ● – rain), or barometric pressure (1002 mb).
Meteorology is based on _______________ . Therefore, predictions are not always accurate.
The basic shape name of a cloud can be combined with the appropriate prefix or suffix listed below as clues to
the weather conditions that may result.
 Combinations of those shapes can be used with nimbus, which means “rain”, for example, cumulonimbus
or nimbostratus.
 A cumulonimbus cloud, also called a _______________ , is often part of thunderstorm conditions that
may accompany a _______________ front.
 The prefix alto- may also be used to indicate _______________ clouds formed at about 2-6
kilometers up into the atmosphere, for example, altocumulus or altostratus.
