Weather
What is the conditions of the atmosphere for a location called?
Weather
High pressure days will lead to what type of weather?
Clear, sunny skies
Stratus Clouds
Which front is attached to the boundary of a High pressure system?
Cold Front which comes in quickly and is STORMY!
What event/phenomenon can affect weather around the globe and causes wet and cooler weather in North Carolina?
El Nino which is identified by the warmer than normal water in the Pacific Ocean
What are three of the six factors that are used to describe weather?
Temperature, sky conditions, Wind, Precipitation, Barometric Pressure, Humidity
What type of Air Mass (air pressure system) follows a Cold Front?
A high pressure air mass.
These clouds are puffy and have flat bottoms.
Cumulus clouds
What air pressure system is following a Warm front (which consists of some precipitation from the warm air rising)?
A low pressure system.
What moves air masses and fluctuates between them across the United States?
Which factor describes how warm or cold it is?
Temperature
When we have rainy weather, what type of air pressure are we experiencing (low or high)?
Low Pressure
How do you describe cirrus clouds and where are they generally found?
Thin and wispy or feather-like and are found at the high elevations
Where would a continental polar air mass originate?
Over land from the one of the poles. In the U.S. it would be from the North Pole. It would be associated with a High pressure system because the air would be cool and dry.
How does air move between pressure systems?
From High to Low
How do we describe wind?
A) by it's speed
B) by the direction from where it originates
C) by the direction it is going
D) Both A and B
Wind is described by its speed and the direction from which it originates (Answer D)
Ex. NE 7 MPH means the wind is blowing from the North East at 7 miles per hour
What type of air is associated with a High Pressure system?
Cold and Dry Air
Why are clouds important to study?
They help us predict weather.
What would an air mass that originates over water near the equator be called?
A maritime tropical air mass. (which would have warm, moist air so would be a low pressure system)
The cool, dry air of the high pressure system is heavy because it is denser
More Info: (denser particles are packed closely together whereas the wet, warm air particles of a low pressure system are further apart and float up until they condense and become heavy enough to fall as precipitation.)
How does generally Weather move across the United States?
From West to East
A low pressure system.
Which clouds are associated with thunderstorms?
Cumulonimbus cloud. (Additional information: These are classified as vertical clouds.)
How would a barometer tell you if a high pressure or low pressure air mass was coming into your area?
If the air pressure is dropping (getting lower) then that tells you a Low pressure system is coming--potential for rainy days ahead.
Why does the wind at the beach blows from the sea to the land during the daytime but blows from the land during the nighttime?
During the day, the land heats up faster than the water, therefore the air above the land is hot, humid and rises causing low pressure over land. Remember wind moves from H to L.
At night, the land cools off quicker than the water, therefore the air above the land is cooler (H pressure), therefore the wind blows toward the water (where the pressure is L).
