Half the chapter concerns water vapour itself and half is on the tropical dynamics of the atmosphere. There is material on the determination of relative humidity, tropical scaling, convection, quasi-equilibrium, radiative-convective equilibrium etc. I have tried to treat these topics in a similar style to the other topics in my book, so it is not a conventional 'tropical meteorology' chapter. The chapter is not finished, and I would like to include more material on large-scale tropical circulation, but it is readable. I will likely make additional changes and additions in the weeks ahead. The link also contains chapters on the stratosphere, gravity waves, equatorial waves and the equatorial ocean circulation, etc.</div><div class="" style="font-family: Menlo-Regular;"><br class=""></div><div class="" style="font-family: Menlo-Regular;">I would be most grateful if you would pass this message on to anyone who may be interested, especially postdocs and students. I would be even more grateful to receive comments on any and all aspects of the work, from both experts and beginners alike. </div><div class="" style="font-family: Menlo-Regular;">The material can be downloaded from this page:</div><div class="" style="font-family: Menlo-Regular;"> <a href="http://tiny.cc/Vallis/aofd" class="">http://tiny.cc/Vallis/</a><a href="http://empslocal.ex.ac.uk/people/staff/gv219/aofd/" class="">aofd/</a></div><div class="" style="font-family: Menlo-Regular;">or</div><div class="" style="font-family: Menlo-Regular;"> <a href="http://empslocal.ex.ac.uk/people/staff/gv219/aofd/" class="">http://empslocal.ex.ac.uk/people/staff/gv219/aofd/</a></div><div class="" style="font-family: Menlo-Regular;"><br class=""></div><div class="" style="font-family: Menlo-Regular;"><br class=""></div><div class="" style="font-family: Menlo-Regular;">Apologies if you receive more than one copy of this email.</div><div class="" style="font-family: Menlo-Regular;">Many thanks</div><div class="" style="font-family: Menlo-Regular;">Geoff</div><div class="" style="font-family: Menlo-Regular;"><br class=""></div><div class="" style="font-family: Menlo-Regular;"><br class=""></div><div apple-content-edited="true" class="" style="font-family: Menlo-Regular;">–––<br class=""><br class="">Prof. Geoffrey Vallis<br class="">University of Exeter<br class=""><a href="http://tiny.cc/Vallis" class="">http://tiny.cc/Vallis</a></div></body></html>
