The Nikolai\nDotzek Award goes to three meteorologists with focus on satellite studies. The most prestigious award in the\nglobal severe weather research community is presented every second year in the\nmemory of ESSL\u2019s founding father, Dr. Nikolai Dotzek, for an outstanding\ncontribution to the science of severe storms. <\/strong><\/p>\n\n\n\n

As the new generation of satellites in Europe, the United States, and Japan have been launched, their increased capabilities in terms of available channels and resolution will allow for better nowcasting of severe convective storms. It is a good time to acknowledge those who have contributed significantly to our understanding of the processes that occur on top of the convective storms, how they relate to storm severity, and how they can be operationally detected. ESSL presents the 2023 Nikolai Dotzek Award to three scientists who have strongly pushed satellite meteorology forward. <\/p>\n\n\n\n

Pao Wang<\/strong><\/p>\n\n\n\n

The first awardee\nis Prof. Pao-Kuan Wang, who has used very high-resolution cloud models to\nsimulate the processes at the top of convective storms. Simulations showed that\novershooting tops act as obstacles to the anvil-relative wind. Thus, most of\nthe storm top features that we observe from a satellite, such as cold rings,\ncold-Us, above-anvil cirrus plumes, storm-top gravity waves or ship wave\npatterns result from the interaction between overshooting tops and the ambient\nflow. Wang has also shown that some of these features result from internal\ngravity wave breaking processes, consequently contributing to lower\nstratospheric moistening. Wang was, until recently, director of the Research\nCenter for Environmental Changes of the Academia Sinica and formerly professor\nat the University of Wisconsin in Madison. <\/p>\n\n\n\n

Martin Setv\u00e1k<\/strong><\/p>\n\n\n\n

The second awardee is Dr. Martin Setv\u00e1k, who in the late 1980’s described various forms of increased 3.7 micron cloud top reflectivity of convective storms and discussed its possible link to storm severity and updraft strength. Later he elaborated this concept with Dr. Charles A. Doswell. Together with Dr. Vincenzo Levizanni, Setv\u00e1k formulated a concept of above-anvil cirrus plumes above convective storms on satellite imagery. He also contributed to the categorization of various storm-top phenomena, such as cold rings, closely collaborating on these topics with Prof. Pao K. Wang. Setv\u00e1k is the father of the so-called \u201csandwich imagery\u201d, a combination of infrared and visible channels, which is now in widespread use across the world. Martin Setv\u00e1k has formally retired but still works part-time at the Czech Hydrometeorological Institute (CHMI).<\/p>\n\n\n\n

Kris Bedka<\/strong> <\/p>\n\n\n\n

The third awardee is Kristopher Bedka, who together with his team made significant strides toward the automation of the detection of both overshooting tops and above-anvil cirrus plumes. Using large records of these phenomena and their properties, Bedka investigated their statistical relationships with severe weather beneath them. His recent work concentrated on the automatic detection of high ice water content in deep convective storms, adversely impacting aircraft engine and air probe performance. He demonstrated the utility of 1-min super rapid scanning for analysis of satellite-observed cloud properties. His ongoing work expands towards wind profiling with an airborne doppler aerosol lidar – to only mention one of several fields of activity – and offers great promises for nowcasting and improving severe storms climatologies. Kris Bedka is affiliated with the NASA Langley Research Center. <\/p>\n\n\n\n

The Nikolai Dotzek\nAward trophy represents a massive hailstone. The prize money is 1000 EUR\ntogether with an invitation to the European Conference on Severe Storms (ECSS).\nThe award was instigated by the European Severe Storms Laboratory (ESSL) in\n2011. The handing over of the award trophy usually crowns the dinner of the\nECSS conference and will take place this year in Bucharest, Romania, on the\n10th of May.  <\/p>\n\n\n\n

The ESSL aims to contribute to the preparedness of European society for the impacts of severe storms by advancing scientific understanding, building human capacity, and fostering cooperation within Europe in this field. <\/p>\n\n\n\n

ESSL provides training to forecasters, scientists, and policymakers on topics related to convective weather. ESSL participates in research projects and organizes the European Conference on Severe Storms to improve and stimulate the exchange of knowledge on severe convection. ESSL aims to establish and maintain close relationships with national weather services and research institutes to strengthen pan-European collaborations. ESSL maintains the European Severe Weather Database, to support research based on observations of severe convective weather or any related impact. <\/p>\n\n\n\n
