Instruments/etc.
Which weather instrument is used to measure air pressure?
barometer
What two types of weather do cirrus clouds bring?
fair weather or an approaching warm front
What type of weather does a warm front bring?
long periods of precipitation and increasing temperatures
What type of weather is associated with areas of low pressure?
counterclockwise circulating winds that often result in rainy and/or stormy weather conditions
What are the 3 climate zones in order from the equator moving towards the poles?
tropical zone, temperate zone, and polar zone
Which weather instrument is used to measure wind speed?
anemometer
What type of weather would you predict to experience soon if you looked outside and observed stratus clouds low in the sky?
long periods of precipitation
What type of weather does a cold front bring?
thunderstorms (sometimes tornadoes) and cooler temperatures
What type of weather is usually associated with areas of high pressure?
more fair weather with winds circulating around the system in a clockwise direction
Which climate zone experiences consistently warm temperatures year round?
tropical zone
What is the driving force behind all of Earth's weather?
the Sun
What type of weather would you predict if you viewed white cumulus clouds in the sky?
Fair weather
What type of weather does a stationary front bring?
a long period of precipitation
Temperatures in locations above the Jet Stream are generally ________ compared to the temperature in locations below the Jet Stream.
colder or lower
Which climate zone experiences 4 seasons?
temperate
What are 2 places or aspects of weather where convection currents can be seen at work?
global winds
ocean currents
What type of weather would you predict if you viewed dark cumulus clouds in the sky?
rain or thunderstorms
Describe the symbols for a cold front and a warm front.
cold front- blue triangles pointing in the direction it is moving
warm front- red semicircles pointing in the direction it is moving
The closer an area is to the Jet Stream, the greater the chance of __________ is.
precipitation or thunderstorms
Name at least 4 factors that influence climate in local regions:
latitude
elevation
shape of land (topography)
distance from water
global winds
ocean currents
Which TWO instruments measure humidity?
hygrometer and sling psychrometer
In a convection current, why does warm air or water rise and cold air or water sink?
Cold air is more dense, so when it sinks it pushes the warm air that is less dense up. OR Warm air is less dense, so it rises, and cold air is less dense, so it sinks.
Describe the symbols for stationary and occluded fronts.
stationary- red semicircles and blue triangles on opposite sides
occluded- red semicircles and blue triangles on the same side
In which direction does the Jet Stream flow? (west to east or east to west?)
west to east
What is the difference between the California Current and the Gulf Stream?
The California Current flows north to south on the West Coast and carries cold water that brings cold, moist air to the surrounding area, while the Gulf Stream flows south to north on the East Coast and carries warm water that brings warm, moist air to the surrounding area.
