Koppen Climate In Class Exercise
This exercise can either be done in MICRODEM or with Google Earth.
- Perform a complete install
- Replace the EXE and help files, and insure you are running a
version dated 2012.10.3 or later
- Follow directions in the help file. You want "Climates
lab", under Tutorials and labs, Physical Geography.
- If you filter the database, you can display just the climate category
you want. CLASS=D* will show all the D's.
- If you right click on a map or the graph, you can copy it to the
clipboard and then straight into PowerPoint.
Download the following data sets:
- If you do not have Google Earth, perform a
Earth download and install the program on your computer. If
you have done this, clicking on the links below will download the files from
the internet and open then in Google Earth.
- Download data files, either of the following:
- Climate_stations.kmz: This has 2482
climate stations from "National Climatic Data Center and World
Meteorological Organization, 1998, 1961-1990 global climate normals CD-ROM, Version 1.0".
For each station, we have computed the Koppen classification. The KMZ
file has the station data, and a climograph. The are voids in
countries that do not share their data, and in regions where recording data
has not been a priority. With this version you can turn on/off
- KOPPEN_GRID.kmz: this is a
½º by ½º grid with the Koppen climate class at
each point on land, for the time period 1976 to 2000. This will be a
point data file, and you can see the individual points as you zoom in. You can turn on/off individual categories.
Data originally from
the University of Vienna.:
Google Earth hints:
- On startup, it is a good idea to clean out any extraneous layers which
will be in "My places" or "Temporary Places". You can right click on
either an individual layer, or the highest level "My places" or "Temporary
Places" and then select either "Delete" or "Delete contents".
- In Layers, there is an option for photos. This will let you get
pictures nearly anywhere on earth, and many are very appropriate for
- Use the checkboxes in the table of contents to hide and show layers.
You might want to limit what appears from Layers, since it is easy to
clutter the map and not be able to see what you want. You can also
show just a single climate category.
- Extracting graphics: To copy the current map on screen in Google Earth, go to Edit, Copy
- To copy a climograph, click on the colored square marking the station to
bring up its data table and climograph, and then right click on the
climograph and pick "copy image".
We will break the class into groups, each of which will prepare a Power Point
discussion of a single climate category in the Koppen classification. Your
presentation will include:
- A map showing the location of the category in the world. You might
need separate views of two hemispheres.
- One representative climograph from North America, showing what conditions are
like, and additional climographs from both the northern and southern
hemispheres (unless that category does not occur there).
- A representative picture of the landscape with the climate.
- A listing of the rules that determine this category. You might get
this from either the textbook appendix or Wikipedia.
- A discussion of why this climate occurs where it does, and what it means
for those areas.
||Section 1001 Number
|A climates (3 categories)
|B climates (4 categories)
|Cf climates (3 categories)
|Cs and Cw climates (4 categories)
|Df climates (4 categories)
|Ds and Dw climates (5 categories)
|E climates (2 categories)
Ultimate learning goal:, upon which you will be tested on both the next test
and the final exam:
- General characteristics of each major category
- Way that temperature and precipitation combine to produce the categories
- General understanding of how the different categories are distributed
over the earth
- Ability to look at a climograph and visualize what conditions at that
location would be like, and where it could be located.
You will turn in the PPT next Friday. The presentation will run a
maximum of 3 minutes; and someone else might present it, so insure there is
enough on the slides for a reasonable person to do the presentation instead of
you (or for you classmates to view the show on their own, and learn enough for
what will be on the exam and final).
