Latest Event Updates
This map (like GIS Map #11) shows the mean centers of population for three racial minority groups…this time in the City of Seattle. In addition, it also displays the standard deviational ellipse for each population. This gives us a sense of the spatial concentration vs. dispersion of the population from the mean, as well as the the amount of integration of the populations with respect to each other. A technical report, detailing my methodology and analysis, accompanies the map I’m turning in. I’m sure the map isn’t perfect (at least I feel I can never get them perfect, regardless of my excellent grades on these maps). But I’m just going to say I’m happy that I even know how to use this amazing software at all. This is my final map of the semester and for my undergraduate time at South Dakota State University.
Sorry for the long hiatus from posting. I’ve had a lot of things happening lately, keeping me busy. However, I finally have some time open to post, so here’s some updates:
-I’ve just completed my final regular class meeting of my undergraduate career. I formally graduate on December 18th (next Wednesday) as will be noted on my final transcript. I’ll receive my degree diploma sometime in March or April. I’m planning on traveling back to Seattle on the 18th and staying through Christmas Day.
-As far as finals…I have a total of 3 final projects and one final. One project I completed yesterday, leaving the other three. I have to complete a Speech final (Thursday), group project for Wildlife and Fisheries (next Tuesday), and a GIS Final Project (next Wednesday). The GIS project I will complete this week along with the Speech Final, leaving the weekend to deal with the group project.
-My GIS project will be similar to GIS Class Map #11, except it will be dealing with the City of Seattle. I’ll be mapping out the mean centers of minority population as well as standard deviational ellipses in order to visually understand the level of concentration or dispersal of the minority groups in the city. I have to create the map of Seattle on my own, using US Census GIS data (which will include of course the demographic information), do the calculations, and construct a good map. Then I have to write a brief report detailing my methods, procedures, and reasoning behind what the map is explaining.
-I’m still planning on attending Mississippi State University online for the graduate meteorology program. I accepted federal aid which was offered to me to pay for college, making the plans officially set. I’ll be starting classes on January 13th. In addition, my fiance and I are planning on moving back to Lincoln, NE at the beginning of February.
That’s about all I can think of right now!

This map depicts the the rates of child hospitalization for asthma per 10,000 children in the designated communities of Chicago as well as the amount of particulate pollution emitted (in tons) by industrial facilities; both during the year of 2002. This map is of course based on the premise that emitted pollution may be a causative agent for child asthma attacks within the metro area.
Today is GIS Day. GIS stands for “Geographic Information System” and can be used to store, interpret, manipulate, and analyze geographic data as well as create useful maps. GIS is used in all sorts of fields which acquire and must interpret geographic data, including meteorology. It can be used to reveal spatial relationships, study changes in geographic features over time, and study how different variables interact with each other. Unlike a static map, layers of data can be added or removed, merged, clipped out in a GIS. Statistical calculations can be made. It really is an amazing technology which continues to grow in popularity. Meteorology has seen a big spur in it’s application in recent years.

Here are a couple of examples of maps I’ve created using a GIS:
The verification of severe weather events superimposed on the 13 UTC (7am CST) Sunday Nov. 17th outlook map. Meteorologists get things wrong sometimes…but they work their butts off to get things right when it matters the most. Yesterday’s severe weather outbreak as a perfect example of that. To see the animation of the previous forecast outlook days, see the previous post HERE.
They did a damn good job of forecasting today’s tornado outbreak. This animation shows the previous forecast severe weather outlooks issued by the National Weather Service Storm Prediction Center in Norman Oklahoma beginning Wednesday into Sunday morning. Note, the NWS began mentioning the possibility of a regional severe outbreak on TUESDAY, however, because of computer model inconsistencies, it was declared that predictability was too low to delineate a threat area (defined in the extended outlooks as a 30% chance of any type of severe weather within 25 miles of a point). So there was at least 5 days advanced notice of something cooking which meteorologists could convey to the public, with some honing in of the threat on Wednesday, with a clearer picture of what region was under threat by Thursday and Friday. By Friday, a large slight risk area was drawn out, with a moderate risk area added by Saturday and a high risk by Sunday as confidence became very high of a tornado outbreak. The high risk was specifically related to the tornado and high wind threat, which was realized today.
