Snowfall measurements are not always accurate because
Depths change once know something wind can blow the snow into drifts????
25
The Kinds of clouds are
Cirrus Cumulus Stratus Cumulonimbus
26
Levels where clouds form at
Cirrus clouds form at the highest altitude Cumulus clouds form at middle altitude Stratus clouds form at low altitudes
27
Appearance of clouds (what they look like)
Cirrus clouds appear wispy and feathery (malls tell)?? Cumulous clouds appear puffy Stratus clouds appear like a flat and gray blanket
28
The kinds of precipitation are
Liquid precipitation or rain | Solid precipitation which comes in many forms
29
The kinds of solid precipitation are
Hail, sleet, and snow
30
Draw a cold front, warm front, and stationary front
Good job
31
Occluded front
When cold air runs into warm air, it pushes up as it rises, it condenses. Clouds form and storms may follow
32
Cold front
Warm air rises over cold air flows underneath
33
Warm front
Front row on the air moves against cold with steady rain
34
Stationary front
Stays in one place and looks like Cold air is on one side and warm air is on the other side in a strait vertical (up and down) line
35
The weather in an area is affected by
The air mass that is passing
36
The front happens when
One air mass meets a different air mass
37
Kinds of fronts
Cold front Warm front Stationary front
38
When a cold air mass moves into an area where the Air mass is warm
Dence heavy a cold air mass pushes up the lighter warm air
39
A stationary front is
A boundary by which two different air masses and whether moves
40
A stationary front forms when
The time the temperature and humidity of the air masses moved behind the front
41
The jetstream is
A high altitude wind caused by large temperature differences in air masses
42
The jetstream moves
Air masses
43
Over North America the jetstream moves from
West to east
44
High and lows what are the systems?
Low pressure system | High pressure system
45
Knowing the location of low pressure system and high-pressure systems and tell you about
Local weather conditions
46
A low-pressure system is
A large air mass with low pressure in the air
47
Since warm humid air has low-pressure, it usually brings weather that is
Warm and stormy
48
high-pressure system is
A large air mass with the highest air pressure in the center
49
Since cool, dry air has high pressure, this system usually brings
Dry, clear weather
50
On a weather map, symbols represent different variables like
Cold friends and warm fronts
51
Cold fronts are shown by
Bluelines with blue triangles
52
Warm fronts are shown by
Red line of half circle
53
Meteorologists are
Scientists who study Earth's atmosphere and weather
54
Meteorologists predict whether by
Measuring variables
55
Are meteorologists predictions always accurate, why or why not?
No because sudden changes in one variable can change the weather
56
How is technology used to study weather
Weather balloons, radar and satellite
57
Weather balloons
Measuring height in the atmosphere
58
Radar provides information about
Precipitation and wind
59
Satellites provide information about
Temperature, wind, moisture, clouds and cloud cover
