21. Natural Climate Processes

Version 1.02c of just this chapter was uploaded to the Practical Meteorology web page on 7 Sep 2018.  It replaced v1.02b (2017).   The main reason for this change was that readers expected and desired Fig 21.8 to be the accurate representation of the orbital and climate signals, not the crude approximation from the Sample Applications.   Similarly, Table 21-1b near the end of the chapter was expected to have all factors for all the terms, not just the first 10 factors.

p798-802.  Need to include all 20+ terms from the Laskar article, instead of just the first 4 or 5 terms.  Otherwise, the equations don't give the right answer for today.   (Laskar, J., Robutel, P., Joutel, F., Gastineau, M., Correia, A.C.M., Levrard, B. : 2004, A long term numerical solution for the insolation quantities of the Earth. A&A 428, 261-285 (2004), DOI: 10.1051/0004-6361:20041335). • Note: there is a nice website that calculates the orbital parameters using all the terms in Laskar et al.  See http://vo.imcce.fr/insola/earth/online/earth/online/ .  [thanks to Harald Pleym, Porsgrunn, Norway.]


CAUTION: The full-book pdf, as well as printed copies produced by authorized publishers, still have the 2017 old version 1.02b.  See v1.02b errata below.

p798, right column, Table 21-1.  In caption, mention that this table shows only the first 4 or 5 terms in the summation equations for use in the Sample Applications. Also mention that all the terms are in Table 21-1b at the end of the chapter.

p798, right column, section 21.2.1.1, in both of the last 2 paragraphs in that section, mention that all 20 factors are given in Table 21-1b at the end of the chapter, and that Fig. 21.8 shows the exact solution with all the terms.

p799.  Replace the top 4 graphs in that figure with the exact solutions, as provided the website http://vo.imcce.fr/insola/earth/online/earth/online/ .   Also, modify the caption to state that it shows the result of using all terms from Table 21-1b near the end of the chapter

p800, left column, Sample Application.  Add at the end of line 2 of the question "using N = 4."  Also, modify the Exposition to discuss how this answer almost agrees with the exact solution of 22.268 deg as found from Fig 21.8 based on all the terms in the series equation.

p800, right column, 2nd sentence after eq. (21.13), mention that Table 21-1 shows the first 4 terms of the series equation, and that all 23 terms on in Table 21-1b near the end of the chapter.

p801, right column, Sample Application.  In the question, state "for N = 5."

p801, right column, Sample Application.  Change the Check and Exposition to be: "Check: This value is smaller than the exact value of 0.01628 from the curve plotted in Fig. 21.8.   Exposition: The eccentricity at year 2000 (i.e., almost at present) causes medium climatic precession."

p802 left column, Sample Application.  At the end of the question, add "using the small number of N values given in Table 21-1."

p802, right column, last paragraph.  Change first sentence to be: "All the information above was used to solve eq. (21.16) for average daily insolation at latitude 65 degN during the summer solstice for 1 Myr in the past to 1 Myr in the future."

p829, right column, exercise E9(§):  Change to: " Table 21-1 shows only the first N = 4 or 5 terms for Earth’s orbital factors.   Use all the terms in Table 21-1b, on the next page to calculate and accurately reproduce the first 3 graphs in Fig. 21.8."

p830, expand Table 21-1b to include all the terms from the Laskar paper.

.


22. Atmospheric Optics

.

p841, left column, last sentence of section 22.2.3.  Add additional sentence at end of that section: "When the setting sun shines through large raindrops under a thunderstorm, zero-order glow can cause brilliant yellow-orange-red colors that seem to light up much of the sky."

.

.

Appendix C: Notation

.

pC881-C888.  This new appendix did not exist in the original PrMet v1.02b.  It was added in July 2018.  Page numbering is temporary.
