Air Masses
Equatorial air masses develop near the Equator, and are warm
air mass
What is a fact about weather fronts?
What are 7 things that weather maps show?
temperature, dewpoint, wind, cloud cover, air pressure, pressure tendency, and precipitation.
What can affect surface ocean currents?
global wind systems that are fueled by energy from the Sun
What affects deep ocean currents?
differences in the water's density, which is controlled by temperature (thermo) and salinity (haline)
What causes air masses to move
Differences in air pressure
What creates a weather front?
the boundary between two different air masses,
What are weather maps made of?
ground-based weather stations
What is the strongest surface ocean current?
Antarctic Circumpolar Current
Do ocean currents change?
because of the climate crisis, these currents may be weakening and slowing down,
What are 5 examples of air mass?
continental polar, continental arctic, continental tropical, maritime polar, and maritime tropical.
Do weather fronts cause rain?
What are the two types of weather map?
the surface map and the upper-air maps.
Are ocean currents slow in surface?
slow-surface
Why are deep ocean currents important?
they redistribute water, heat, nutrients, and oxygen about the ocean.
What is it called when air masses meet?
Weather fronts
How fast do weather fronts move?
30 to 80 km/h.
How do you predict weather on a weather map?
which direction fronts are moving and which way the wind is blowing in a certain area.
How do surface currents affect weather?
currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Do tides affect deep ocean currents?
Tides create a current in the oceans, near the shore, and in bays and estuaries along the coast.
What is it called when air masses meet?
weather fronts
How can fronts affect humans?
change the air pressure.
What type of data do weather maps display?
the current state of the atmosphere over a larger area.
Does temperature affect ocean surface currents?
Warming temperatures result in weakened currents.
What are the two types of deep ocean currents?
currents driven mainly by wind and currents mainly driven by density differences
