Do you have a school report coming up and feel like this:
instead of like this:
Not to worry. That Internet search engine, Google,™ has come up with a new way to list information at different reading levels.
Let's say you're a super genius expert on tornadoes. Tell Google™ to list advanced articles:
What Causes Tornadoes:
Tornadoes
form in unusually violent thunderstorms when there is sufficient (1) instability and (2)
wind shear present in the lower atmosphere.
Instability refers to unusually warm and humid conditions in the lower atmosphere,
and possibly cooler than usual conditions in the upper atmosphere. Wind shear in this case refers to the wind direction changing, and the wind speed
increasing, with height. An example would be a southerly wind of 15 mph at the
surface, changing to a southwesterly or westerly wind of 50 mph at 5,000 feet
altitude.
This kind of wind shear and instability usually exists only ahead
of a cold front and low pressure system.
If you're a tornado newbie, ask Google™ to list basic articles first:
How do tornadoes form?
Most tornadoes form from
thunderstorms. You need warm, moist air from the Gulf of Mexico and cool, dry
air from Canada. When these two air masses meet, they create instability in the
atmosphere. A change in wind direction and an increase in wind speed with
increasing height creates an invisible, horizontal spinning effect in the lower
atmosphere. Rising air within the updraft tilts the rotating air from
horizontal to vertical.
And if your report needs a little something extra, and you're sending it to your teacher through a computer, then your go-to search engine is the free Microsoft™ Clipart files:
