Second warning: Exam 3 Monday, April 9: end of volcanoes, tsunami, and weather through TORNADOES; review Thursday 5 PM, UPSTAIRS in Rm 223. NAU IS in session this Friday… ANNOUCEMENTS

Solomon Islands: April 2, 7.40 am (local time there); 2.40 pm April 1 here purple is subduction; red is transform

Homework! due Wednesday (remember this will all be on the website) Go to recenteqsww/Quakes/us2007aqbk.php#summary and any public news sources you chose (tell me which) recenteqsww/Quakes/us2007aqbk.php#summary Read the website summary, and follow the link to the Pacific Tsunami Warning Center. You are after event #1

Homework! due Wednesday Send me an that answers these questions: –what caused the tsunami (what tectonic activity in the area)? –when was the first warning sent out by the PTWC? where are the places the PTWC issued warnings for (where on Earth?)? what were the projected arrival times? what did the PTWC say by way of warning? –how long did it take before they expanded the warning? –when did they start getting arrival times (look carefully)? where were the first places to report arrival/wave height, etc.? –how are wave heights measured? –where were the biggest waves recorded? –when were warnings cancelled? –what damage/casualties occurred and where?

Homework! due Wednesday Send your work in an with > in the subject line. If you send an attachment, be sure the name of the attached file is >. (your name)

QUIZ (as promised) YOUR OWN WORK please, not with your neighbor close up books and notes please you need 1/2 piece of paper (tear carefully please…find to use a whole sheet) you have until 5 minutes for this when you’re done, turn it over and pass to the middle aisle

quiz 1.In what main part of the atmosphere does weather form? (1 point for where it is, 2 pts for name of the layer) 2.Is the ozone layer in this same part of the atmosphere? (yes or no, 1 point) 3.What kind of clouds build up to form thunderstorms (and tornadoes)? (1 point) 4.e.c. (1 point) what is the shape at the top of a “mature” thunderstorm cloud (draw or give name) PIN_________ (1 point)

Your attention please Some of your peers are getting very tired of the semi-constant chattering that goes on. This includes during clicker exercises, while I am talking, and while others are asking questions I will ask you to leave if it appears that you can’t respect your classmates

Hazardous weather/ tornadoes/hurricanes READ for Wednesday chapter 7: sec. 7.5, including the case study (I will ask about lightning on the exam). Read the survivor story (7.2) for Friday you will need to read 7.6/7.7/7.8. Be sure you can answer the “critical thinking questions” #3, 4, and 5

Clickers!

What is the issue with the name of NAU’s ‘Center for High Altitude Training’? 1.It should be High Elevation 2.Compared to other places with excellent training facilities, we’re not really at high altitude 3.It is named correctly

What is the relation between high- and low-pressure air masses and whether the air mass will rise or fall? 1.High-pressure air falls/low-pressure air rises 2.High-pressure air rises/low-pressure air falls 3.High- and low-pressure air can rise or fall 4.High pressure rises or falls, low pressure only falls

Why does a rain shadow form? Assume wind from the west. 1.Warm air carries little moisture and so the rain shadow is always warm and dry 2.Warm air carries moisture that is deposited on the west side of a mountain as it rises and cools off 3.Cool air carries moisture that is deposited on the west side of a mountain as it rises and warms up

South of Flagstaff is something called the Mogollon Rim -- the topography rises up from the desert and the Verde Valley to the Colorado Plateau Verde Valley Flagstaff Mogollon Rim

As air masses come up from the desert, where does the most moisture fall? Verde Valley A Flagstaff D Mogollon Rim C B

the Coriolis effect: moving air around the planet importance: air (clouds) move from high pressure to low pressure, but can’t get there in a straight line in the southern hemisphere, clouds turn west CLICKERS please! Cloud moving south turns west

Which hemisphere is this storm in? 1.northern 2.southern Picture from the international space station! N S

Fronts (the last jargon you need) Cold air meets warm (or vice versa) –one mass is moving more than the other –cold front = cold moving into warm –warm front = warm moving into cold –stationary front = neither is moving Which will move up/down when they meet?
