Q

Anemometer

A

Measures wind speed

24
Q

What is atmospheric temperature caused by

A

The absorption of heat from earth and from the sun

25
Q

Weather conditions change due to

A

The movement of air masses

26
Q

Air mass forms when

A

A body of air remains nearly stationary over a large section of earths surface

27
Q

If an air mass forms Over water it will

A

Be moist and low pressure

28
Q

If an air mass forms over land

A

It will be dry with high pressure

29
Q

Continental tropical

A

Hot land
cT
Hot dry air

30
Q

Continental polor

A

cP
Cold land
Cold dry air

31
Q

Maritime polor

A

mP
Cool ocean
Cool moist air

32
Q

Maritime tropical

A

mT
Warm ocean
Warm moist air

33
Q

Prevailing winds and upper air currents

A

Determine the movement of air masses

34
Q

Fronts

A

Boundaries between air masses

35
Q

Cold fronts

A

Leading edge of cooler air

36
Q

Warm fronts

A

The leading edge of warmer air

37
Q

Precipitation is likely to occur at front boundary’s when

A

Warm moist air rises above the cooler air

38
Q

What happens when a front passes

A

There is a change in the weather

It causes cloud formation, winds, precipitation, and air pressure and temperature changes

39
Q

Thermometer

A

Measures air temperature

40
Q

Barometer

A

Air pressure

41
Q

Psychrometer

A

Humidity, dew point

42
Q

Anemometer

A

Wind speed

43
Q

Wind vane

A

Wind direction

44
Q

Rain gauge

A

Amount of precipitation

45
Q

What is weather monitored by

A

Weather balloons that send data to weather stations

46
Q

Doppler radar

A

Detects

Tornados

47
Q

Radar

A

Gives information about the intensity and speed of approaching storms

48
Q

Satellite photographs

A

Show cloud cover

49
Q

Computers

A

Collect and store large amounts of data and compare present weather data to past

50
Q

Tornados

A

Rapidly rotating extreme low pressure storms. Extends down from a thunderstorm cloud. Made when cold air meets warm air. Hazardous winds with flying debris

People should seek low shelter or go under a sturdy structure

51
Q

Thunderstorms

A

Form along a cold front
Lightning and heavy rain
Strong wind hail deadly lightning and the danger of flash floods

People should shelter indoors stay off electronics and stay away from flood areas

52
Q

Ice storms/ blizzards

A

Heavy snow and winds
Can disrupt electric and phone services
Rainfall might freeze danger to frostbite and hypothermia

Stay indoors don’t drive have heat and food and water and medical supplies available

53
Q

Hurricanes

A

Low pressure systems
Form over warm tropical oceans winds are greater than 74 mph
High winds high waves flooding from rain

Have food water and all necessary supplies and stay indoors go to emergency shelter if in a flood prone zone

54
Q

Cold front

A

Mass of cold dense air moves in. Warmer air is pushed up (less dense) and forming precipitation

At the boundary heavy storms occur
Clouds at the front are cumulonimbus
Cool and clear skies come after

When occurring: heavy storms occur
Temperatures drop
Barometric pressure drops

55
Q

Warm front

A

Mass of warm air moves in warm air moves above (less dense) moisture in warm air produces cloud covered skies

Weather that occurs at the bouncy is hours of rain or snow
Cirrus and stratus are formed at the front
After you will find warm weather
Front occurring: steady rain occurs
Temperature increases
Barometric pressure drops

56
Q

Stationary front

A

Occurs when air masses meet and stop moving the air moves sideways whatever front advances first decides which it will be

Cirrus and stratus occur at the front
Weather you will find after is either a warm front of a cold front
