Estimate the Environmental Lapse Rate (ELR) by using linear regression (to 4 significant figures). To copy the table above into Excel, you will need to copy all the data above excluding the headers, select a 13Rx3C region in Excel and do a paste special -> unicode text. This calculation assumes the temperature of running water in this tropical alpine environment approximates ambient air temperature.

[FONT=&quot]How does this lapse rate compare with the global mean lapse rate of 6.5 oC/km?

Select one:
a. It's pretty much the same
b. It is orders of magnitude lower than average
c. It is orders of magnitude higher than average
d. It is a degree or two per km lower than average
e. It is a degree or two per km higher than average

[h=4]Question text[/h]Estimate the 0oC elevation (i.e. elevation where the mean air temperature is 0oC) using your locally determined ELR. Note: this estimation assumes that rises in air temperature are constant throughout the troposphere

[h=4]Question text[/h]By how much has the 0oC elevation risen (in metres) since the 1960s when the observed mean air temperature near the base of the Rwenzori Mountains (1101 mamsl) was 17.4oC rather than 18.1oC?

[h=4]Question text[/h]The main icefields of the Rwenzori Mountains terminate below the peak elevation of approximately 4900 masml. By how much will surface water temperatures need to rise near the base of the mountains for the 0oC elevation to reach these last remaining icefields.

This is your 3rd. post without providing us any of your thought. When you receive a response, you do not let us know whether you succeeded or not.
 
Sorry

Hi, I completed the previous questions well and managed to plug the numbers into my seawater density equation to get the right answers, thanks! It really helped! Took a while but I got there. I then worked on the following questions and got them right too. This is my new struggle because I am unsure how to answer this linear regression question. If you could answer it for me then I will be able to see how you got there and hopefully understand the concept a little better. Thanks a lot!
