Know the conditions for tornadoes to form? See if you can make your own…
Check out the video weather 101 from the link below. Nat Geo comes through again
Quizlet flash cards to keep you fresh on air masses names and descriptions
Here is a practice test
AND ENTER THIS TEACHER CODE:
with the same temperature and moisture throughout!
Air Masses March
Part I Moisture Content:
Mar-i-time Air Mass forms over the sea
Holds moisture or HUMIDITY
Con-ti-nen-tal Air Mass forms over land
The Air is dry, please understand!
Part II Air Temperature:
I don’t know but I’ve been told,
TROPICAL is warm and POLAR is Cold
I don’t know but Limpert said,
ARCTIC air will freeze your head
Continental-dry land; Maritime -moist sea
Tropical- warm air, Polar cold- no heat
Unit Test Review: Start NOW
But the good news is that pressure always moves from high to low. Below are some flash cards on winds to help you prepare
Ode to Local Winds
- If someone ever asked you, how to draw a local wind,
what would be the very first step ,and how would they all end?
Earth heats up unequally, good scientists would say,
land heats up much faster, all throughout the day.
Land warms the air by conduction ,so the air becomes less dense,
The Warm air spreads and rises, it’s now making perfect sense?!
But over the sea, air is colder on a bright and sunny day,
the waters cooler than the land ,so we jump in and play!
Cold air creates more dense ,and hence, high pressure air,
pressure is higher over water,than land, right over there.
Differences in air pressure, makes breezes that will blow,
high to low, is the only direction that all air pressure can go.
Wind begins wherever air tem-pera-ture is the least,
all day long from the ocean, the wind blows towards the beach.
winds are named from the place where cold, high pressure air is found,
In the night, air is coolest up above the cold cold ground.
At night land cools quickly, losing most of its heat
So nighttime local winds, flow from land out to the sea.
Folks, if you can remember, where the coolest air will be
You’ll always know ,right where to start
And that they all end in breeze!
