Meteorologist
Meteorologists can predict the weather by analyzing and
interpreting data
from observations and tools: Current weather conditionsWeather mapsSatellitesRadar images. Changes in weather conditions can indicate a change in the pattern of weather. Slide3
Changes in Weather Conditions
Wind speed is measured using an
anemometer
and indicates a change in atmospheric flow patterns Wind direction is measured using a wind vane (also known as a weather vane) and indicates the direction of advancing air masses. Temperature is measured using a thermometer. Changes in the air masses result in changes in the temperature. Slide4
Changes in Weather Conditions
Humidity
can be measured with sling
psychrometers or hygrometers. Humidity is a measure of the percentage of water vapor in the air. Increased levels of humidity can be associated with a high probability of precipitation. Air pressure is measured with a barometer. A rise in air pressure indicates fair weather while a fall in pressure indicates stormy weather conditions advancing Slide5
Clouds
Basic
shapes of clouds
are associated with weather patterns. Types of clouds:CirrusCumulusStratusSlide6
Cirrus Clouds
Cirrus clouds are
high and wispy
and signal fair weather or an approaching warm front Slide7
Cumulus Clouds
Cumulus clouds are
puffy with flat
bottoms and signal fair weather. When they are darker, they may signal rain or thunderstorms, as they develop into cumulonimbus clouds (thunderheads). Slide8
Stratus Clouds
Stratus 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. Slide9
Weather Maps
Weather maps can help predict weather patterns
by:
indicating high or low pressure systems (isobars) movement of air masses and frontstemperature ranges (isotherms). Slide10
Satellite
Satellite images are used for
seeing cloud patterns
and movements. For example, hurricane clouds and movement can be observed using satellite images. Slide11
Radar
Radar
images can be used to
detect: cloud coverRainfallstorm location or intensitycloud movementthe potential for severe weather (for example, hurricanes or tornadoes).
