WORDS FOR JOHN

1. WORDS FOR JOHN

2. John Lumley I am so sorry that I cannot be present for this celebration of John Wyngaard’s career. John was one of my earliest students. He was not quite finished when I went on my first sabbatical, and Henk Tennekes supervised his final year; I am happy to share him with Henk. Since I went to Penn State in 1959 and collaborated with Hans Panofsky, small scale meteorology had been one of Henk’s and my major interests. It was natural that John would gravitate to that field, where he has spent the best part of his career. Meteorology is a small and somewhat hermetic field. It requires not only talent, but hard work and application to gain the trust and attention of the meteorologists. I think John has been one of the most influential and trusted people working in fluid-mechanical meteorology. As a meticulous and creative experimentalist, he has been directly or indirectly responsible for much of the small-scale data on which the modern field is based. At the same time he has contributed great insight to the interpretation of this data. This combination of expertise and insight is extraordinarily rare. John has been a splendid colleague, and I wish him all the best in the coming years. With best regards, John L. Lumley Cornell University

3. Henk Tennekes … One of the highlights of our intertwined careers was the 1972 AMS Workshop on Micrometeorology, which was organized by Duane Haugen. Both of us were much impressed by the fact that Duane had invited us, youngsters compared to Hans Panofsky and Coleman duPont Donaldson. Those were great years, which I remember with gratitude. Best,  Henk

4. Duane Haugen and Chandran Kaimal Dear John, Forty-three years ago you joined our group at the Air Force Cambridge Research Laboratories as we were preparing for the 1968 Kansas Experiment. A fresh Ph.D. from Penn State, you started contributing to the preparations with ideas for hot-wire measurements of energy dissipation rate. The experiment is memorable for many reasons. The flat terrain and sleepless nights are hard to forget, and so is the image of you and Owen Cote balancing on a tall ladder to reach your probes on a 4-m mast. Most satisfying for us were the three years we had to analyze and make sense of the data. Many people were involved, but your contribution stand out for its breadth and significance. It was an extraordinary productive period. The 1973 Minnesota Boundary Layer Experiment also yielded important papers. Our scientific interestes eventually took us to different places, NOAA and NCAR, but we stayed in touch. As we wish you the very best on your retirement, we remember happily the eight years we shared as colleagues and friends. With warmest regards, Duane Haugen, Chandran Kaimal Boulder Colorado, Hamilton, New York

5. Peter Bradshaw John - I'm sorry not to be here in person, but Jim Brasseur suggested I should send you greetings from the sunny, beautiful and bankrupt State of California. I forget where we first met face to face. Doubtless at a conference. I first met you on paper when your thesis work on a curved mixing layer was published in 1968, and since then I have logged about 15 of your papers, which I'm sure is a small fraction of your output. I haven't been a very faithful admirer because I'm not directly involved in meteorology as such: to me it's just one of many reasons to study turbulence. Like almost everybody in the room I have studied atmospheric turbulence....from the inside of an airplane. John, about 25 years ago you chaired a panel to explore whether NASA Ames' work on turbulence should be centralized, in preference to having the work done in several different branches. I was worried that the long-haired turbulence would be stuck in an ivory tower without much interaction with the rest of Ames. Fortunately I was either ignored or shouted down, and the panel recommended the establishment of what is now the Ames/Stanford Center for Turbulence Research. John, you did a good day's work. Best wishes for a happy retirement - like all retirees you'll find there still aren't enough hours in the day to do everything you want to. I hope the Nittany Lion gives a friendly roar when you leave. - Peter Stanford University

6. Monique Leclerc John, Evaluating the impact that every action, every word has on the life of budding scientists is unlikely, even for someone like you. I will always treasure the time Chandran Kaimal took me into your office as I had just taken my first job at Utah State. You and I had a vivacious discussion on canopy flows and this, in turn, led to my six-month visit at NCAR in MMM under Don Lenschow's group. I treasure this memory because it is at NCAR that I met with scientists who, in a myriad of forms, had a lasting impact on my career. As you have opened the door to me, I cannot help but wonder to how many other scientists you have done that to. It is as if, through that brief contact, I was allowed to get a glimpse of who you are, John, and that is so much more than  'just' a bright scientist. With my kindest, warmest, most heartfelt wishes, Monique Y. Leclerc University of Georgia

7. Bill Easterling Jose, I am honored to receive your invitation to speak at John Wyngaard's symposium.  Unfortunately, I have an out-of-town commitment that day and therefore cannot attend and speak.  I hope that my deepest apology for missing this event is conveyed to John and the attendees.  William E. Easterling, DeanCollege of Earth and Mineral Sciences Penn State University

8. Sergej Zilitinkevich … I am very sorry for missing this great event. John Wyngaard is the key name in boundary-layer meteorology and geophysical turbulence. I admire his ground-breaking ideas and his clear and elegant way of presentation. … Please convey my congratulations, admiration and  best wishes to John, Yours Sergej University of Helsinki Brian Sawford Unfortunately I am committed … What a shame - I would certainly have enjoyed participating. I hope that the Symposium is a great success. Please pass on my best wishes to John. Regards, Brian Monash University

9. Branko Kosovic Dear John, I would like to join, in spirit, if not in person, your colleagues who gathered in State College this week, in celebrating your seminal contributions to the field of atmospheric turbulence. Personally, I will be always in debt to you for introducing me to this fascinating field, selflessly sharing your knowledge and scientific insight, and setting me on the path of scientific research. Your insight, clarity of exposition, rigor, and excellence will always be beacons to those who embark on scientific exploration of atmospheric turbulence. Thank you and best wishes, Branko NCAR

10. Mike Raupach Thank you very much for the honour of this invitation.  I regret that I won't be able to participate… Please convey my very best wishes to John Wyngaard for the occasion, and for his retirement.  His career has been inspirational to many, including me. With best regards  Mike Raupach CSIRO, Australia Chris Bretherton Thanks very much for your generous invitation, and I certainly hold John Wyngaard's contributions to the field in high esteem.  Unfortunately, I … will not be able to come.Chris Bretherton  University of Washington

11. Robert Wood … I greatly admire Dr. Wyngaard's contributions to the field of boundary layer meteorology which have helped me in my own research to understand cloudy boundary layers. Unfortunately, … it will not be possible for me to attend …  RegardsRobert Wood University of Washington Fontina Chow …I wish I could attend, as John Wyngaard's work has inspired and set a framework for my LES turbulence modeling approaches. … I think Bob Street will attend, so I will ask him to convey my best wishes to John… Best regards,Tina University of California, Berkeley

12. William R. Stockwell Dear John,I will never forget how deeply you contributed to my early career development and how much I appreciate it.  There were three things in particular.1)  Your leadership in the founding of the Acid Deposition Modeling Project (ADMP) at NCAR critically shaped my lifetime career path.2) Our discussions on the role of sub-grid scale processes andatmospheric chemistry lead to my lifelong interests and has shapedmany of my papers.3) Your student, Richard A. Brost, became one of my closestcollaborators and friends in the development of new science.For all of this I publicly thank John Wyngaard for his inspiration andhis mentorship to a (then) young scientist at NCAR.Bill Stockwell Howard University

13. Joseph Klewicki James McWilliams I had heard via Peter about John's retirement, and I'm glad you're organizing a symposium. Over the years I've greatly enjoyed John as a colleague. Unfortunately I … will not be able to participate in the symposium. … Jim UCLA … I am sorry to miss this, as John’s impact on the field has been very significant and certainly worth honoring. Best Regards, Joe University of New Hampshire
