CATEGORY 1: WEATHER TOOLS & FUNCTIONS
: This instrument measures how fast the wind is blowing
What is an anemometer?
This type of weather is typically associated with low pressure systems.
What is stormy/rainy/cloudy weather? (Accept: storms, rain, clouds, bad weather)
This front occurs when a cold air mass moves toward a warm air mass
What is a cold front?
This air mass is both moist and warm.
What is maritime tropical?
This instrument measures the amount of rain that falls.
What is a rain gauge?
A thermometer measures this form of energy in the atmosphere.
What is thermal energy?
Explain using the concept of density: Why does low pressure produce stormy weather?
What is: Low pressure means air is less dense, so air rises, cools, and water vapor condenses into clouds and precipitation?
A warm front is characterized by this air mass moving toward a cold air mass.
What is warm air? (Accept: "warm air moving toward cold air")
Continental polar air masses are characterized by these two properties.
What is dry and cold?
A weather balloon measures conditions at different levels of this
What is the atmosphere?
This tool uses a wet bulb and dry bulb to measure relative humidity
What is a sling psychrometer?
High pressure systems bring this type of weather, and it occurs because denser air sinks.
What is clear/sunny/fair weather?
This front occurs when two air masses don't have enough energy to replace each other.
What is a stationary front?
Name the air mass that is moist and cold.
What is maritime polar?
Explain the difference between a cold front and a warm front using air movement
What is: A cold front has cold air moving toward warm air, while a warm front has warm air moving toward cold air?
Name TWO instruments that measure moisture or humidity in the air.
What is a hygrometer and sling psychrometer? (Accept: weather balloon if they explain it measures atmospheric conditions)
Draw and label an air pressure station. Explain how the activity demonstrated the impact of air pressure on weather formation.
What is: (Answers vary—accept diagrams showing pressure differences, rising/sinking air, and connection to weather patterns)
Name the front that occurs when cold air overtakes warm air that was previously advancing
What is an occluded front?
This air mass forms over land in tropical regions, making it dry and warm
What is continental tropical?
Using air mass terminology, describe the conditions that would create a maritime tropical air mass and explain where it forms.
What is: Maritime tropical forms over warm ocean water (tropical), making it moist (maritime) and warm (tropical)?
