earth science quiz weather maps

what information is shown on a station model?

it shows temperature, wind speed and direction, air pressure, cloud cover, and precipitation

how is a climate map different from a weather map?

weather map show cold front and warm front by using lines and specific patterns on them to tell you what a cold or warm front is climate map show air pressure temperature dewpoint, and pressure.

continental

dry - forms over land

maritime

humid - forms over water

polar

cold

tropical

warm

arctic

extremely cold

what two characteristics defined in air mass?

temperature and humidity

what type of air mask causes hot in human summer whether in Texas?

maritime tropical

what kind of air mass brings cold dry air from Canada?

Continental polar

what is the difference between Maritime and Continental air masses?

Continental forms overland with a dry sensation, and Maritime forms over water with humidity

why do Maritime polar air masses bring lots of rain to Seattle?

it brings in cold humidity to Seattle, which causes it to rain

cold front

cold air pushed warmed air up quickly - thunderstorms and heavy rain - blue triangle as symbol

warm front

warm air slide over cold air - light rain and warmer after - red semicircles as symbol

stationary front

Air masses don’t move - long periods of rain in a clouds - red and blue is the symbol

occluded front

cold front overtakes warmer after front - clouds, steady rain and or snow - purple alternating is the symbol

what happens when a cold front passes through an area?

Cold air will push up very quickly also causing heavy rain and storms

how does weather change after a warm front moves in?

The weather goes from hard rain and thunderstorms to light rain with a warm temp

which front causes a long periods of steady rain?

occluded front

what does inoculated front mean on a weather map?

it shows a cold front overtaking a warmer after front

high pressure

air sinks - clear and calm - clockwise and outwards direction

low pressure

air rises - cloudy and stormy - counterclockwise and inward direction

what type of weather is linked to low pressure systems?

Stormy with clouds

what direction do winds move around a high pressure system?

The winds move clockwise in outward

which system brings fair sunny weather?

High-pressure

What is happening to air (rising or sinking) in a low pressure system?

Rising

coriolis effect

caused by earth’s rotation - makes winds and currents move

• moves right for Northern

• moves left for Southern

what causes the coriolis effect?

something caused by Earth’s rotation

how does it affect the movement of air in the northern hemisphere?

Causes the northern hemisphere to move to the right

how does it differ in the southern hemisphere?

It causes a southern hemisphere to move to the left

isobars

lines on a map connecting equal air pressure

• close together = strong winds

• far apart = calm winds

weather maps use front symbols like triangles and simmer circle to show boundaries

what do isobars represent on a weather map?

They represent air pressure connecting

what does it mean when isobars are close together?

There are strong winds

what front symbol shows warm air advocating?

A triangle

to form precipitation there are three things that are needed:

moisture - lift (air rising and cooling) - concrete station nuclei (dust particles)

why does lifting air cause rain?

Because of the air rising and cooling

west wind

blows from the west to the east

east wind

blows from the east to the west

why do we name wins by where they come from?

Helps us understand whether patterns

which pressure systems is associated with clods and precipitation?

low pressure

maritime air masses originate over what?

oceans

which air mass originate in the southwest desert of the US?

Continental tropical

what happens when a cold air mass rapidly takes over a warm front?

occluded front forms

an at mass tears on its source region’s what?

temp and humidity

in a low pressure system, air flows where?

towards the center

which pressure system is associated with fair weather?

High pressure

lines on a map that connect points of equal pressure are called what?

isobars

A record of weather data for a particular site at a particular time is a what?

Station model
