This storm rains cats and dogs - and lightening and thunder!
What is a thunderstorm?

When this is heated unevenly, it moves around causing winds and air currents.
What is air?
100
This measure of height above the Earth's surface affects air pressure
What is altitude?
100
As this increases, air pressure decreases because of the amount of water vapor in the air.
What is humidity?

A kind of current, this spark caused when electricity in a thunderhead discharges also graces the head of Harry Potter.
What is lightning (lightning bolt)?
200
"It's a twister! It's a twister!" This rotating funnel-shaped cloud contains winds that blow up to 480 km per hour.
What is a tornado?
200
This is the transfer of heat through the movement of a gas or a liquid. When it happens in the air, it forms winds.
What is convection?
200
This is a large region of air that has a similar temperature and humidity.
What is an air mass?
200
This storm has a low pressure closure that causes a circular pattern of winds to form. Hurricanes and tornadoes are actually types of these.
What is a cyclone?
300
These loops of air flow are caused by differences in temperature and pressure.
What are convection currents?
300
These intense seasonal winds bring a lot of rain, that can cause floods.
What is a monsoon?
300
This trade wind blows steadily in predictable directions and over long distances, almost circling the Earth.
What is a global wind?

What is the climate?
300
The layer of gases closest to the Earth's surface.
What is the troposphere?
400
These currents move heat and water around the world through water vapor and the seas. Just make sure not to swallow the salty water!
What are ocean currents?
400
This is a large swirling storm that has low pressure at it's center. Someone warn New Orleans!
What is a hurricane?
400
These scientists specialize in the study of the Earth's atmosphere and weather- and also help us choose what to wear!
What is a meteorologist?
400
These meeting places between air masses are never behind!
What is a front?
400
A tornado forms in two parts: a thunderhead and this.
What is a funnel cloud?
500
This is actually caused by a burst of heat - but it seems louder than hotter!
What is thunder?
500
This "baby" storm makes the temperature of the ocean rise and causes the air pressure to call over the water.
What is El Nino?
500
If the weather man is always wrong, why not shake things up a bit and make your own this? Just make sure to make your best prediction before the event happens!
What is a forecast?
500
These huge waves whipped up by hurricane winds create a bulge of water in the ocean known as this. It can cause water levels to rise or surge very suddenly!
What is a storm surge?
500
When an area of low pressure air is surrounded by higher pressure air, it is called this. Also a name for a calm business deal.
