air masses and fronts.
What do warm air masses bring?
clear,dry and hot weather
whats a weather map?
a map that shows the weather in different forms.
where are ocean currents?
on the surface of the ocean.
where are ocean currents?
deep in the ocean.
What is a front?
The place where 2 or more air masses meet.
why are weather maps useful?
how many factors cause surface currents?
3
how many factors cause deep ocean currents?
1
how do scientists classify air masses?
Temperature and air.
what does Mp represent on a weather map?
Maritime polar or hot and dry.
What are the 3 factors that cause surface currents?
global winds,the coriolis effect. Continental deflections.
what causes deep currents?
surface wind driven currents.
How are fronts and air masses related?
A front is a space between 2 air masses and air masses are on the surface
what does the big H on the weather map represent?
high pressure.
what are continental deflections?
When surface currents meet continents, the currents deflect, or change direction.
why are deep currents important?
They redistribute water, heat, nutrients, and oxygen about the ocean.
what happens to the warm air mass on a unclouded front?
The warm air rises as the air masses come together.
what are 3 types of weather maps?
temperature maps, pressure maps,streamline maps.
why are surface currents important?
they transfer heat from the tropics to the polar regions, influencing local and global climate.
what do deep currents carry?
heat,oxygen and nutrients.
