I'm going to move this forward here to about 2005, beginning of 2005, and then I'm gonna press plus, plus, plus. I'm going to slide this back a little bit further to 2008. So here I am, I'm going to slide it back to start in 2005. Now the critical thing here is, remember that you're looking in 2005, so you've got to arrange this historical imagery thing - slider not a thing - to show 2005 in detail. Sometimes I don't know which is which, but you just have to click back and forth. Okay, my historical imagery is on and I can turn it off with this little globe here, it's actually a clock. And this part of the lab is all about your historical imagery, which is up here. And I'm gonna look at this general vicinity for the storm, which was called Katrina, most of you probably remember Hurricane Katrina. So in we go towards North Claiborne Avenue. Let me go to North Claiborne Avenue in New Orleans, which is one of your locations. So let's say I'm gonna go to New Orleans. And then we're going to start looking at historical imagery for the labs.

Okay, so that's the first control that you're gonna need to know how to do for the first part of the lab. Click on this point here, I get 95 miles per house wind speed, 938 pressure. So if I go back out aways again and I look at Hurrican Irma when it came into Florida. You click on the point, the wind speed is 115, the pressure is 938 millibars, and the precipitation is 60.6 inches. And I'm going to zoom in on the Texas coast and you can see these points, which provide the actual data for landfall, and you can see this point here is Harvey 10, which is very close to the landfall. Okay, so I'm going to start off by looking at meteorological data for Hurricane Harvey, for example, which will show you the sorts of controls you need. So if anything goes wrong with this lab, with the Google Earth buzzes lab, please look at your historical imagery to make sure you're in the right time window. Okay, so here I'm showing all data between 20. The problem was that I didn't have the right time window in my historical imagery.
And why don't these all three occur? The problem is here I've got my historical imagery up on the left, which we're going to use for later on, and I'm gonna back this out a little bit, and I'm gonna go forward a little bit, and you can see them all come on. And here you can see the tracks for these three storms - Harvey, Maria, and Irma. Here are my three recent hurricanes - Maria, Irma, and Harvey. These hurricanes are grouped by decades and you can see here 2015's, which is 2015 to 2017. Click on the triangle to open up the different decades. And I'm gonna start by showing you hurricane track controls. And I have two files that I've opened over here at the KMZ files - temperature anomalies and hurricane tracks, on the left side here. So today I'm going to show you the controls for the module 2 lab. We HIGHLY recommend you watch it to learn exactly how to manipulate the files and use the historical imagery. The video below will help you with operations in Google Earth. Remember, you only get one attempt at the graded assignment. If you have any questions about the practice questions, please let us know. Once you feel good about these questions, move on to the graded assignment. Note also, we break up the 17 decades.Īs in the lab for Module 1, we begin with some practice questions that you can take in the Lab 2 practice submission, where you will receive the answers to the questions. Also, there are a few storms including Betsy whose names do not show unless you zoom in close.
Please make sure that the slider at the top left has the relevant range of dates on it, otherwise, you will not be able to view tracks for the desired storm. We definitely recommend that you don’t try to look at the storms all at once or you will see a maze of lines. The storm tracks have points that show the wind speed and pressure at different stages in its development. Both maps have sliders at the top left of the screen that allow you to look at storms as well as temperature over time. You can switch back and forth between maps. The second, Temperature Anomalies kmz file, shows average August temperatures for each year calculated relative to the average temperature between 19. There are two Google Earth maps to load, the first, Hurricane Tracks kmz file, shows tracks of storms from 1900 to 2017. to observe the relationship between storm intensity and warming.to determine the main causes of damage from storms including wind, rainfall and flooding, and storm surge.In this lab, we will observe the tracks of the largest storms of the last century, and learn about the impacts of those storms on land.
