fronts
what are the 2 types of front
cold front and warm front
define climate
climate is like weather but over a long period of time instead of day to day
define air mass
a large body of air that always has the same temperature and moisture level
define wind
the air in the atmosphere that is made by pressure
what are global winds created by?
Coriolis effect
explain what happens in a cold front
a cold front is where cold air mass pushes warm air mass up
how many different climates are there?
there are 5 different climate
how many different air mass did we talk about in class?
we talked about 4 different air masses
True or False - is hot air heavier than cold air?
False
which type of wind occurs north/south and blow away from them
polar Esterline's
explain what happens in a warm front
warm front happens when warm air mass stretches over cold air mass
name the 5 different climate
-tropical
-dry
-cold
-polar
-mild
how many are cold air masses?
how many are Hot air masses?
2 cold
2 hot
is hot air high pressure or low pressure
low pressure
where do the prevailing westerlies occur from?
occur from the west/east to the poles
define fronts
where 2 air masses (cold/hot) meet and weather happens.
what are the 2 cold air masses
maritime polar- cold and wet
continental polar- cold and dry
what does cold and hot air make when they meet?
wind
what type of winds occur near the equator and flow from north/south
trade winds
what are the 2 hot air mass
maritime tropical- hot and wet
continental tropical- hot and dry
is cold air or hot air, high pressure?
cold air
what is the Coriolis effect?
the spin of the earth and differences of temperature between the equator and polar areas.
