On monday May 9, 2005 I have defended my thesis at the University of Utrecht, the Netherlands. The defense went very well (I thought so, at least :-), and according to the translation of the latin text by three experts present at dinner, I am now officially dr. ir. Zelle.
The title of the thesis is "On the evolution of sea surface temperature in the tropical Pacific", the topic is El Niño - Southern Oscillation. It consists of an extensive introduction of the El Niño phenomenon, and three chapters which have been submitted to / published in Journal of Physical Oceanography and Journal of Climate.
You may download my thesis to read it, but all copyrights apply. You may not distribute the manuscript in electronic or printed form without my explicit permission. Chapters 2, 3 and 4 are under copyright by the American Meteorological society as they have been / will be published in a journal. If you want a paper copy of the thesis for easier reading you can print it out (120 pp), or email me at email@example.com for a printed and bound copy.
