Air Pressure
What kind of weather is usually associated with a high pressure system?
Clear, sunny skies
What is a cold front? Give one example of weather that might happen when a cold front passes
A cold front is when a cold air mass slides underneath a warm air mass causing it to rise. When having a cold front you will see heavy precipitation and cooler weather AFTER the front
What is the Gulf Stream?
A warm ocean current that starts in the gulf and goes past the coast
List each step of the water cycle
Evaporation
Transpiration
Condensation
Precipitation
Runoff
Name two weather tools used to measure conditions and what each one measures
Answer could vary
Describes what a barometer measures and explain how its reading help meteorologist predict weather
A barometer measures air pressure. A barometer can help a meteorologist predict the weather by telling if there is a low or high pressure. If the barometer is low, there will be rainy weather. If the barometer is high, there will be clear and sunny skies.
What is a warm front? Give one example of the type of weather that might happen when a warm front passes
A warm front is when a warm air mass goes over a cold air mass causing it to sink. A warm front brings light precipitation and warmer weather AFTER the front.
Explain how warm ocean water like the Gulf Stream can change air temperature along the coast
The warm air from sea or coast will rise and push towards the land which will cause an increase in temperatures that inland will be not receive.
Explain how heat energy causes evaporation
When heat is added to a liquid it causes the liquid to get very very hot and become a gas.
What does an anemometer measure? Why is it important for predicting severe weather?
It measures wind speed. It can help tell the level of the severe storm. Higher winds= greater damage
Explain why a low pressure system often bring clouds and precipitation.
A low pressure system brings clouds and precipitation because it causes more evaporation to take place in the water cycle.
Describe what happens when a cold front meets a warm front
When a cold front and a warm front meet they collide with each other. This causes light rain showers at a constant rate.
Why does the Coast of NC have milder winters than inland of NC?
The coast will hold more heat from the sea. Inland does not have that source of heat during the winter months.
Describe the difference in evaporation and condensation
Evaporation: Heat is added to water. This causes the water to become a gas.
Condensation: Heat is taken away from gas. This causes the gas to become a liquid.
Explain how to use a rain gauge over a period of a week
When rain falls, the rain gauge will catch it. When you want to monitor rain fall for multiply days, you empty it out and restart.
Compare and contrast how temperature and humidity can change air pressure in an area
*Hint: don't forget about the word dense
Higher temperatures bring less dense air. When moisture is added it causes more dense air which then cause low pressure system.
Explain how the movement of a warm front can change daily temperatures and clouds over a costal town
When the warm front moves in you will see warmer weather and an increase in cloud coverage.
Describe one way the ocean's influence can influence the amount of precipitation in coastal NC during cooler months
During the cooler months, the gulf stream will bring heat which adds moisture in the air. When there is moisture in the air, there is a greater chance of precipitation happening.
Describe how a glass of water creates water droplets on the outside of the glass
Water vapor from the surrounding air condenses to form water droplets on the cold glass
Which tool would be best to use to measure a sudden change in weather conditions?
If a barometer at 8:00AM reads falling pressure and the temperature is rising, what weather would you predict later that day
I would predict a low pressure system. This will bring storms and rainy weather.
Describe all fronts and what weather comes with each front
Cold Front: a cold air mass goes underneath warm air mass causing it to rise. You will see warmer weather before the front. Heavy rainy weather during the front, and cooler weather after the front.
Stationary Front: a cold air mass and warm air mass collide. You will see light rain showers throughout the front.
Warm Front: A warm air mass goes over a cold air mass causing it to sink. You will see cooler weather before. During the front you will see rain showers. After the front you will see an increase in temperatures
How might a warmer-than-normal Gulf Stream affect hurricane development?
If the Gulf Stream is warmer than normal, this can cause more power to a hurricane if the hurricane reaches the gulf stream
If a plant does not have enough water, what is a good word to describe how the plant may look?
Wilted
Thermometer = Rising temperature
Wind Vane = winds shifting from north to south
Pressure = quickly falling
What could meteorologist expect next?
Increase in clouds, wind, and precipitation, low pressure system
