On February 16th we received the sad news that Prof. Sergej Sergeevich Zilitinkevich passed away. Sergej was a giant in the field of boundary-layer meteorology, turbulence, fluid dynamics, in science at its highest level. We owe him many among the most brilliant ideas and developments in atmospheric scientific fields. Sergej was a leader, a maestro forever young, an enthusiastic researcher, a friend, a person really listening, a real scientist. His work and his smart smile will remain forever in our memory.
