Apologia Physical Science, Module 8, Weather and Its Prediction

Play  Quizlet.  Just scroll down and find the Module you want.  
►How each of these are formed:
hurricanes, thunderstorms, tornadoes, lightning, blizzards.
►Tips for predicting the weather.
►A recipe for weather. (At the bottom, click on each of the ingredients to learn more.)


1) p. 183, Thunderstorm animation - He goes through it a little fast, but very good.
Watch twice.


2) p. 185, Dew Point and Relative Humidity
"...whenever you see clouds, you know the temperature inside of them and dew point are equal."


3) p. 185, Weather Barometer - high and low pressure
The higher the pressure and humidity, the higher the dew point.


4) p. 186, How to Predict the Weather - from a veteran fisherman and sailor, Jeff Spira. See more videos, some about building boats, at SpiraInternational.com


5) p. 186, Predicting Weather - NASA


6) p. 188, Science Explains Lightning - how the negative charge builds


8) p. 188 - What is lightning? - stepped leaders, return stroke.
Good, but doesn't show the negative and positive charges that are both in the cloud and on land.  See previous video.


9) p. 188, How Lightning Works - Unable to chop at TubeChop, but content relative to Module 8 is from 1:12-3:40.


10) p. 192, Hurricane Ike Forecast
with Joe Bastardi (Bu-STAR-dee)
He talks about where the hurricane may hit.  Around 2:05 minutes, you will see three arrows pointing toward the coast of Texas.  He mentions Corpus Cristi (about where the bottom yellow arrow is) and Brownsville (the very tip of Texas), and that there were fewer people in an area between there.  Hurricane Ike actually ended up hitting at the top green arrow, in Galveston, Tx as you can see in the next video via satellite.


11) p. 192, Hurricane Ike via Satellite, hits Galveston, Texas.
Slow time-lapse video of 4 days.  I recommend hitting play, letting it download while you do something else for a few minutes (watch a video!), then slowly dragging the button across.  You will see that Joe was right about it slowing down. In the warmer waters the hurricane did gain back strength that was lost down to a Category 1 after hitting Cuba.  According to Wikipedia, Hurricane Ike hit land "as a strong Category 2 hurricane, with Category 5 equivalent storm surge."


11) p. 195, Hurricanes and Meteorologists - from NASA

Full Video of the above, plus 2 more:
Ahead Above the Clouds, Part 1, Part 2, Part 3

12) p. 195, Hurricane Hunters - NASA.  At 2:40, note the "eye wall" that is mentioned on p. 194 of the text.
My class had to draw and label the graph as it appears around 3:40.
