Weather forecasting and Maps Edhead stuff we learned
100
What layer of the atmosphere do we live
troposphere
100
Name 2 ways to prove that air is a substance
fanning myself, pushing air out of a syringe, taking up space in the syringe, smell it if there is an odor
100
Definition for the word Front
the area where 2 large air masses meet and do not mix
100
definition of an air mass
large body of air with similar temperature humidity and pressure IF formed over the poles the air mass will be colder than if it forms over the equator
100
How do weather patterns generally move in the US
from west to east
200
layer that we find Ozone in and why is ozone so important
the stratosphere and it protects us from UV radiation
200
2 Main gases of the atmosphere
Nitrogen and Oxygen
200
How does a warm front form
warm air collides with cold air mass and gets pushed up.
light rain or drizzle no severe weather
200
tropical air masses are (give temp and pressure info)
Polar air masses are (give the temp and pressure info)
tropical air masses are warm and low pressure
Polar air masses are cold and high pressure
200
H on a weather map (explain what type of weather and what the H stands for
High pressure and clear skies or sunny----
High pressure does not necessarily mean warm
300
What does the mesosphere protect us from
meteoroids from crashing into earth
300
What is the definition of wind
The horizontal movement of air
300
How does a cold front form and what type of weather does it bring?
cold air hits warm air and warm air is pushed up fast
severe weather may occur thunderstorms, snow storms tornadoes
300
Maritime air masses form over the ____________
Continental air masses form over the _____________
Maritime over the oceans
Continental over land
300
L on a weather map= what type of weather and what does the L stand for
Low pressure and cloudy and rain
Low pressure does not mean warm
400
How are layers of the atmosphere divided?
by the temperature differences look at the temp line on your poster
400
Air moves from areas of high pressure to low pressure. Give one example from my demonstrations and one from what happens in nature
the candle "burns" up air in the glass and looses pressure: outside pressure pushes water into the glass
Cold air=high pressure sinks toward the equator
Warm air=low pressure rises towards the poles
400
stationary front how does it form
cold and warm air meet but neither can overpower the other both stay around for a while
bring days of clouds and precipitation
400
For each of the air masses tell the temperature and if it is dry or moist air
mP
cP
mT
mP=cool temp and very moist or wet
cP=cold and dry
mT= warm and wet
400
How do you calculate how far a warm or cold front will move in a particular time
multiply speed of the front in miles per hour, by time in hours
500
Why does most weather occur in the troposphere
because there are convection currents in this layer that move air from one place to the other
500
How does the atmosphere keep our planet warm
by trapping warm air acts like a blanket
500
cold front symbol
warm front symbol
cold front blue line with triangles
warm front red line with semicircles
500
the reason why warm air rises and cold air sinks
warm air molecules are more spread out weighs less and can rise
cold air molecules are less spread out more tightly packed so cold air tends to sink
500
Name some things you need to predict the weather
front speed and direction
how far the front is from the location you are forecasting
type of front (warm. cold stationary)
current weather conditions for the location you are forecasting
High or Low pressure
