<div>Dear planetary community,</div>
<div><br>
</div>
<div>We are pleased to announce that our next MIT Planetary Lunch Seminar will be given by
<b>Prof Cheng Li</b>, University of Michigan (details below). <a href="https://chengcli.io">Cheng’s research</a> includes serving as a Co-I on the JUNO team, focusing on the microwave radiometer. His team has recently made new observations that allow them to
constrain the depth of the polar vortices. </div>
<div><b><br>
</b></div>
<div><b>Cheng is available to meet with people on Monday and Tuesday:</b> https://docs.google.com/spreadsheets/d/1GQVkzR0vY6DuYK6AKFgJ1bBUP_VLsGsz-veO_KXfuWk/edit?gid=0#gid=0</div>
<div><br>
</div>
<div><br>
</div>
<div>Cheers, </div>
<div>Wanying & Jason</div>
<div><br>
</div>
<div><br>
</div>
<div><b>Date</b>: Tuesday April 15th</div>
<div><br>
</div>
<div><b>Time</b>: 12:30 — 1:30 (arrive a few minutes early to serve lunch)</div>

<div><b>Title</b>: Vertical Structure of Polar Vortices on Jupiter</div>
<div><br>
</div>
<div><b>Abstract</b>: Jovian planets are fluid planets lacking a well-defined solid surface or an influential boundary layer. Their atmospheric dynamics are primarily driven by solar insolation, moist convection, and atmospheric waves. The ongoing Juno mission
has revolutionized our understanding of giant planet dynamics by providing three-dimensional observations of Jupiter’s weather layer, using spacecraft orbits for spatial coverage and spectral instruments to probe depth.</div>
<div>One of the most intriguing discoveries is the presence of stable, non-merging circumpolar cyclones at Jupiter’s poles. These features stand in contrast to predictions from many shallow water models. The Juno extended mission has provided further insight,
particularly through data from the microwave radiometer at the north pole, revealing new details about the vertical structure of these polar vortices.</div>
<div>In this talk, I will present recent Juno observations of Jupiter’s poles, discuss the structure of them and implications for their formation.</div>
