Lab 4: Climate Variables and the Change in Western United States’ Levels Abstract:
The purpose of the lab was to determine the outcome of the daily time steps from 1958-2062 of the Western United States and compare them. That was done by using three factors in three different time periods; was placed in a global change model simulation of complex models and were then compared to determine the outcome of the experiment. What all these graphs meant was that the overall Ocean Mixed-Layer Temperature went up and this of course affected the Precipitation and Snowfall levels directly. Background/Introduction:
The objective of the assignment was to find out the comparisons of fluctuating levels from the years 1958 to 2062 in the Western United States and compare them to see if there was any change. The factors used for comparison were Precipitation, and Ocean Mixed-Layer Temperature. Problem:
1) What are the future Changes predicted by the model for at least three climatic variables? 2) How does future predicted climate for the western United States differ from current or past ones? Methods and Materials:
What was needed was the global change model called EdGCM (http://edgcm.columbia.edu/). In EdGCM, Snowfall, Precipitation, and Ocean Mixed- Layer Temperature were used to see different outcomes of North America’s change in climate. Then, three different time periods were run through the program to project the results. The time periods were: 1958-1962, 2008-2012, and 2058-2062. The time periods were then compared with their respective data. Precipitation and Ocean Mixed-Layer Temperature were compared in dates 1958-1962 versus 2008-2012 and 2008-2012 versus 2058-2062. Once the maps and the data was collected and compared, the change over time was apparent.
These graphs show the affect the climate had/has/will have on Precipitation, Snowfall, and Ocean Mixed- Temperature overall years. As shown, Ocean Mixed- Temperature had a slight...
